BREAST TENDERNESS
Why are my breasts so tender?
Breast tenderness is a very common symptom. It is
rarely associated with breast cancer, but a thorough
exam by an experienced physician is important to be
sure.
Most women experience at least some increase in
sensitivity or tenderness in their breasts as their
menstrual cycle In some women this can become quite
severe. The tenderness may be diffuse, involving all
of the breast tissue, or it may be localized to one
breast, or one area of one breast. Though it usually
lessens after the menstrual period it may be constant.
It is clear that changing hormone levels in the blood
stream are the primary explanation, but there may be
other contributing factors. Certain medications may
increase tenderness, including birth control pills,
estrogen or progesterone (Premarin, Provera, Ogen,
Climara, Estratest, and others), and medications which
contain xanthines (Theodur, caffeine containing
stimulants). Caffeine seems to cause increased breast
tenderness for many women, though it seems to have no
effect in others. Marked breast tenderness frequently
occurs in the very early stage of pregnancy also.
Sometimes a cyst can develop and enlarge rapidly,
causing localized tenderness. Less commonly, an area of
infection may occur which can be extremely tender.
If you have recently noticed that your breasts are more
tender, you should be sure to do a good self-exam of
your breasts. See if can identify a specific area that
hurts, and feel for any lumps. Look for any visible
changes such as a visible lump, or a dimpling of the
skin, or redness. Schedule an appointment with your
physician, and take a list of your current medications.
Be aware of how much caffeine you are using, including
coffee, tea, sodas, chocolate, and any
caffeine-containing medications, such as diet pills or
stimulants. Be able to pinpoint when your last menstrual
period was, and whether is was normal or not. Ask your
physician's office if you should have a mammogram or
other studies before your appointment, and if you should
bring your mammograms with you.

Will I need a biopsy?
For
most women with breast tenderness, the physician's exam
will not identify any problem which needs a biopsy.
However, occasionally there is an associated lump, which
could be a fluid-filled cyst, an abscess, or a solid
growth of tissue. Such findings will likely require a
procedure, such as use of a needle, or other sort of
biopsy or removal. This may frequently be done at the
time of the initial visit. (Please note that some
insurance companies do not cover procedures to be done
on the same day as your exam. If not, you will be
scheduled to return for the procedure after your
insurance company has given authorization .)
Cysts can be treated simply with drainage of the fluid
through a needle. The pain from the fluid drainage is
similar to what you would feel if you have a blood test
done. The cyst fluid usually has a greenish, yellowish,
or brownish tint. There is usually no need to "test" the
fluid if it has this typical appearance.
Abscesses usually require a small incision to drain the
infection. For small abscesses, treatment can be done
immediately. The infection causes more surrounding
tenderness than a cyst, so the drainage procedure is
likely to be more painful, but brief. The advantage of
immediate treatment may outweigh the extra tenderness.
Larger abscesses may require drainage in a hospital
setting in order to provide adequate sedation and /or
anesthesia.
Solid growths of tissue may be biopsied with a needle
at the initial visit. Some anesthetic is injected
around the area to be biopsied. The needle is then
inserted into the lump to obtain a sample of tissue for
analysis. An ultrasound machine is frequently used to
place the needle precisely. Most women experience little
or no discomfort with the procedure.
Return to top of article
What can I do to decrease my breast tenderness?
Once
your physician has examined for any possible problems
such as a cyst, abscess or possible cancer, there are
several things you can do. If you are taking in any
caffeine on a daily basis, try cutting out all caffeine
products for a period of six weeks. This simple step
may be all that is necessary. If your tenderness goes
away, you may want to experiment by starting back on
caffeine to see if your tenderness cames back. You may
find that there is a certain amount of caffeine which
you can tolerate without the symptoms.
Both vitamin E and evening primrose oil have been found
to be helpful for many women. Though the exact mechanism
of action is not known, both supplements have been found
to be beneficial in decreasing tenderness. Recommended
dosages for vitamin E range from 400 U to 1000 U per
day. It is available at all drug stores and many
supermarkets without a prescription. As an added
benefit, there appears to be a decrease in riak of heart
disease in patients taking vitamin E on a regular basis.
Evening primrose oil is carried by many drug stores,
though it may be difficult to find than vitamin E. It is
more commonly recommended in England than here in the
United States . Recommended dosage is up to four
tablets per day. It can cause some gastrointestinal
side effects, such as bloating or gas, and changes in
your bowel movements. These side effects are less
likely at lower dosages.
There are many simple measures to try that may help.
If your tenderness is predictable with each menstrual
cycle, you may want to begin taking on over-the-counter
pain medicine, such as Tylenol, Advil, Alleve, or other,
for the week before your period. A good hot bath once
or twice a day can help. Changing to a different bra is
also occasionally beneficial.
Depending on the severity of your tenderness, you may
want to use some or all of these measures. Most women
will obtain sufficient relief with the steps described
above. For the small group of women with persistent
disabling tenderness despite all these measures, there
is a hormonal treatment which is very effective, but
which has a high likelihood of side effects. It
involves use of Danazol, a hormone used in treatment of
endometriosis. Side effects include changes in menstrual
cycle, voice changes, and body hair growth.

Fibrocystic Disease
Breast Pain.
Painful breast tissue is an exceedingly common symptom
but is usually of functional origin and very rarely a
symptom of breast cancer. Haagensen 24 carefully
recorded the symptoms of women presenting with breast
carcinoma and found pain as an unprompted symptom in
only 5.4% of patients. Although not a symptom of cancer,
breast pain is a common reason for patients to seek
medical attention. Breast pain appears to be aggravated
by abnormal menstrual cycles and may be seen in young
women with menstrual irregularity, as a premenstrual
symptom, or when exogenous ovarian hormones are
administered during and after the menopause. In
addition, fibrocystic change, in its severest forms, may
cause disabling breast pain. Although many observers
find painful cystic mastopathy is aggravated by
excessive intake of caffeine, nicotine, or commonly used
antihistamines, other investigators disagree.
Fibrocystic Change (Cystic Mastopathy, Cystic Mastitis).
Fibrocystic change, popularly referred to as fibrocystic
disease, represents a spectrum of clinical and
histologic findings and describes a loose association of
cyst formation, breast nodularity, stromal
proliferation, and epithelial hyperplasia. 34
Fibrocystic change appears to represent an exaggerated
response of breast stroma and epithelium to a variety of
circulating and locally produced hormones and growth
factors. Clinically, patients with fibrocystic change
have dense, firm breast tissue with palpable lumps and
frequently gross cysts. This condition is commonly
painful and tender to touch. Histologically, the lesion
recognized as fibrocystic complex contains macrocysts,
microcysts, stromal fibrosis, adenosis, and a variable
amount of epithelial metaplasia and hyperplasia. All
these changes can occur alone or in combination and to a
variable degree in the normal female breast. Autopsy
studies have questioned whether any of these changes,
except perhaps macrocysts, are abnormal. In fact, all of
these lesions occur commonly in the breasts of elderly
patients and appear to have no particular pathologic
potential. It appears preferable to describe each of the
lesions separately and comment about the extent and
severity of the process. The term fibrocystic disease
should be abandoned in the absence of any well-defined
clinical and pathologic syndrome.
As discussed later, there is no consistent association
between fibrocystic complex and breast cancer. It is
well established that women who have undergone breast
biopsy for any reason, regardless of the underlying
pathology, have a slightly higher risk of developing
subsequent breast cancer. Moreover, the incidence of
finding fibrocystic disease in autopsied breasts from
women dying of causes other than breast cancer exceeds
the incidence of these same changes in cancer-containing
breasts. For those patients with fibrocystic changes,
higher risk appears to concentrate in those whose biopsy
specimens show abnormal ductal and lobular hyperplasia
and, to a lesser extent, cyst formation. Therefore, the
fibrocystic complex appears to be an exaggerated or
abnormal response to otherwise physiologic stimuli in
most patients and represents a health risk only in
certain subsets.

BREAST LUMPS
I just found a lump in my breast. What should I do?
Any
lump in your breast should be checked by a qualified
physician to determine what it is. If you are not sure
whether it's really a "lump", or not, you may wish to
wait through a menstrual period to see if the new
finding is still present. But if it is a definite
lump, you should not delay.
A new lump may simply be a benign cyst, or it may be
the first sign of a breast cancer. In most cases,
additional studies will be done, such as a mammogram, or
ultrasound, and frequently some sort of biopsy is also
necessary. In some cases, where the new finding is not
a distinct lump, you may be asked to return for a
re-exam in a few weeks or months.
Return to top of article
I have a lump, but my mammogram is normal, so it's
not cancer, right?
You must understand that not all cancer shows up
on mammography. Any lump needs to be examined by a
qualified physician, whether it shows up on mammography
or not. If the lump is not seen on mammography, it may
be still need to be biopsied. An ultrasound may be
helpful.
I had a routine mammogram and it showed
"calcifications", or a "nodule". I have been referred
to a surgeon. Does this mean I have cancer?
Screening
mammograms have become an important method to screen for
breast cancer. We have learned that mammograms can
often detect the earliest signs of breast cancer, at a
point in time when it can not yet be felt. Early breast
cancer often shows up as a small cluster of
calcifications, which look like a small grouping of
tiny white flecks on the mammogram, or as a small
nodular area which is more white than the surrounding
breast tissue. But, these same abnormalities
can be caused by breast changes that are not
breast cancer as well. Only about one in six of these
abnormalities end up being cancer when they are
biopsied. But the only way to be sure is to sample the
tissue with some sort of biopsy. This means that most
of those who have a biopsy will find out that there is
no evidence of cancer.

I went for my routine screening mammogram, and I was
told to come back in 6 months for another mammogram. Is
it okay to wait that long if there’s an abnormality on
the mammogram now?
It’s good that you are having annual mammograms done.
Of course, every woman hopes that nothing abnormal will
be seen, and in fact about 90% of women do indeed have a
“normal” mammogram. And of the other 10%, even
though the mammogram may show something abnormal, most
of these women don’t have cancer.
Abnormalities seen on mammograms fall for the most part
into 2 categories; suspicious calcifications, or
densities. Not all calcifications are suspicious, and
it would be too complicated to go into all the subtle
distinctions that are considered in evaluating any
calcifications. Generally speaking, the
calcifications which are small, clustered (and
multiple), and variable in shape and size (this is
called pleomorphic), are the ones that should be
biopsied. Now if the radiologist sees just one or
two calcifications, or if they are not that variable in
size, or if for some other reason, they aren’t that
suspicious, he may recommend a “short term followup”,
which usually means, a repeat mammogram of just the
involved breast in 6 months. It doesn’t really make
sense to recommend a biopsy when the findings are not
that suspicious, since it would require doing biopsies
in 50 women to find the 1 of 50 who actually has a
cancer. As it stands, only about 15% of the abnormal
calcifications which are biopsied (BIRAD 4 cases) are
cancer; the other 85% of suspicious calcifications are
due to benign changes in the breast tissue.
It is important that the radiologist reviewing your
films has lots of experience reading mammograms. At
our institution, all the radiologists who read
mammograms are reading thousands of studies every year.
Our facility is accredited by the American College of
Radiology. We use the most up to date technology for
digital mammography, which provides high resolution
images, and with much less inconvenience for the patient
(rarely do the pictures need to be “done over”).
Those women who are requested to return for followup
films in 6 months in most cases will be given further
reassurance with the 6 month film and then return to an
annual schedule. A few women may be advised to have a
biopsy based on the followup. If you feel anxious
about being told to come back in 6 months, you should
ask your primary care physician for a referral to DeKalb
Surgical Associates for a breast consultation. We
are experienced in evaluating breast abnormalities and
will carefully review your specific case, including the
findings on physical exam, and on mammography. If
appropriate, ultrasound can be performed at the time of
your visit for additional information (though for
calcifications, ultrasound rarely is utilized).

I was told that my mammogram was read as a BIRAD 4.
What does that mean?
When your mammogram is read by the radiologist, he will
categorize the findings according to whether anything
looks suspicious or not. The American College of
Radiologists set up standards for rating mammograms,
which is called BIRADS (Breast Imaging Reporting
and Data System). Here is a table of the possible
designations.
|
Category |
Diagnosis |
Number of Criteria |
|
0 |
Incomplete |
Your mammogram or ultrasound didn't give the
radiologist enough information to make a
clear diagnosis; follow-up imaging is
necessary |
|
1 |
Negative |
There is nothing to comment on; routine
screening recommended |
|
2 |
Benign |
A definite benign finding; routine screening
recommended |
|
3 |
Probably Benign |
Findings that have a high probability of
being benign (>98%); six-month short
interval follow-up |
|
4 |
Suspicious Abnormality |
Not characteristic of breast cancer, but
reasonable probability of being malignant (3
to 94%); biopsy should be considered |
|
5 |
Highly Suspicious of Malignancy |
Lesion that has a high probability of being
malignant (>= 95%); take appropriate action |
|
6 |
Known Biopsy Proven Malignancy |
Lesions known to be malignant that are being
imaged prior to definitive treatment; assure
that treatment is completed |
You can see that the BIRAD 4 classification refers to
findings for which the radiologist feels biopsy should
be considered, even though it might not be cancer.
This designation covers a wide range of suspicious
findings, and for this reason, some radiologists will
further categorize the findings as 4a, 4b, or 4c,
indicating progressively higher suspicion. For example,
if he sees a group of three tiny calcifications, not
very tightly clustered, and all rounded, he may feel
biopsy is appropriate, even though these are most likely
benign, and so may designate this as a BIRAD 4a. If he
sees a “tight” cluster of numerous tiny calcifications
that are variable in shape and size, and perhaps showing
branching, he would predict that these are much more
likely to indicate cancer, and may designate these as
BIRAD 4c. In most cases, both of these situations
are going to require a biopsy, even though the level of
suspicion is quite different.
Return to top of article
I had an abnormal mammogram and have been told to
see a radiologist or surgeon to have a biopsy done.
What does that involve?
It is important that in addition to annual screening
mammograms after age 40, you should have an annual
breast exam by a physician who does a thorough physical
exam of your breasts. This is especially important if
your mammogram is abnormal. If you are referred for a
biopsy, and no breast exam is done beforehand, you might
not have the proper biopsy method, or there may be
findings missed that would alter the recommendations for
biopsy. The surgeons at DeKalb Surgical Associates
are highly trained and skilled in the assessment of
breast problems, particularly mammogram abnormalities.
In most cases of BIRAD 4 abnormalities, you would be
scheduled for a stereotactic biopsy. But if the
abnormality corresponds to something the surgeon can
feel, or can see on ultrasound, a core needle biopsy
with ultrasound guidance is usually a better option, and
this can usually be done on the same day as your first
visit.
A stereotactic biopsy is a clever method designed to
obtain a small but sufficient amount of tissue from the
breast for biopsy when the area of suspicion cannot be
felt, but is seen on the mammogram. It requires some
sophisticated equipment, and a skilled physician, but
usually is relatively easy for the patient. You will
lie on your stomach on a special flat table that can be
raised up; your breast drops through an opening in the
table. A mammogram plate holds your breast stationary
while digital images are taken at two slightly different
angles. This allows the physician to precisely localize
the abnormality in your breast, using a computer that is
hooked up to the table. After injecting some local
anesthesia in the skin of your breast, a core needle is
advanced through the skin to the target, and several
cores of tissue are removed. An x-ray of the removed
tissue will immediately confirm that the suspicious area
has been removed. The procedure usually only takes
about 20 minutes, and is usually painless after the
local anesthetic injection.
In most cases, the physician will place a small metal
marking clip in the area where the biopsy was taken.
This clip is about the size of a tooth filling, and will
not be felt, will not move around, and will not set off
any metal detectors. This marker is important whether
you have cancer or not. If the biopsy shows cancer
(results will usually be available in 2-3 days), your
surgeon will need to remove more tissue from around the
biopsy area. Since the original suspicious abnormality
may have been completely removed with the biopsy, the
marker will be a certain way of knowing precisely where
the biopsy was done. If you don’t have cancer, the
marker will remain permanently in your breast,
documenting that the suspicious area has been adequately
biopsied.

I was seen by a surgeon because of an abnormal
mammogram, and was scheduled to have surgery. They are
going to put a wire in my breast, and then take me to
the operating room for the biopsy. Is there a simpler
way to do the biopsy?
In most cases, the initial biopsy can be done without
placing a wire, and without having to go to the
operating room. Since most such abnormalities on
mammogram are benign, it’s usually better to do a less
invasive biopsy initially, rather than going to the
operating room for a surgical biopsy. There are
exceptions to this, but the surgeon should have given a
logical explanation for why a less invasive procedure
was not chosen. If you don’t feel comfortable with
the recommendation for an open surgical (excisional)
biopsy, you could always request a second opinion.
It is almost always best to know there is cancer present
BEFORE going to the operating room. If it is not yet
determined whether there is cancer, a less invasive core
needle biopsy (either a stereotactic biopsy or
ultrasound guided biopsy) is almost always preferred.
Return

I had a breast biopsy that showed some pre-cancerous
cells. What should be done now?
The term “pre-cancerous cells” might be used for
different situations. There are some benign cells that
are more heaped up and irregular than normal breast
cells, which are considered to be an indication that a
woman is at higher risk for developing a cancer.
There are 2 such categories, atypical ductal hyperplasia
(ADH), and atypical lobular hyperplasia (ALH) or lobular
carcinoma in situ (LCIS). Although these findings
are not cancerous, the possibility of finding a tiny
cancer nearby is high enough to consider a larger
surgical excision of surrounding breast tissue, if these
cell types are seen on a core needle biopsy. Though
estimates vary, the possibility of finding a nearby
hidden cancer in this case is probably about 10%.
I had a breast biopsy that showed ductal carcinoma in
situ (DCIS). What should be done now?
Although no one ever wants to be told that they have
cancer, the finding of ductal carcinoma in situ (DCIS)
is one of those situations where we truly have found a
cancer at a stage where it can be nipped in the bud.
The “in situ” phrase means that we can tell for sure
that these cells have the POTENTIAL to do their cancer
thing (which means, to invade into surrounding tissue
and eventually spread elsewhere), but that they have not
yet invaded even the tissue right around the DCIS
cells.
When DCIS is seen on a biopsy, you will need to have
more tissue removed from your breast
(usually the additional tissue removed is about the size
of an ice cream scoop). This is almost always done as
on open surgical excision in the operating room, either
with sedation or general anesthesia, though sometimes
under local anesthesia. This surgical excision is the
most important treatment, and it is necessary to remove
enough tissue so that none of the DCIS is seen along any
of the margins of the removed tissue.
This is not always as simple as it might seem, because
the DCIS can only be seen under the microscope, and the
tissue is not usually examined under the microscope
until after preserving the removed tissue in formalin
overnight. This method gives more reliable information
than trying to examine the tissue immediately (called a
frozen section). This means that there are some women
in whom the margins will show some more DCIS, and this
will require another trip to the operating room to
remove more tissue. This return to the operating
room is necessary more often than you might think, as
often as 50% of the time at some centers. At DeKalb
Surgical, this is only necessary about 12% of the time.
I wish it would never happen, but sometimes even the
non-invasive cancer cells can extend along the breast
ducts in various directions. Obtaining clear margins is
a matter of experience, compulsion with orientation of
the tissue for the pathologist, and to some extent, how
much additional breast tissue is removed. Our technique
involves the use of a customized surgical device that is
not yet available for general use, which helps to
minimize the likelihood that you would need a second
procedure.
Although surgical excision for clear margins is the most
important treatment, radiation therapy AND 5 years of
hormonal therapy (with tamoxifen) is fairly standard
additional treatment,
with the intention of minimizing the possibility that
you might ever develop another cancer in your breast.
Your surgeon should discuss these issues with you in
more detail. Probably the most important thing to
remember if you have DCIS is that almost all women are
cured of their cancer when it is found at this stage.
Return

I had a breast biopsy that showed invasive cancer. What
should be done now?
You will need to be evaluated to decide on an
individualized treatment plan, based on the specific
details of your case. Several factors must be
considered, including the type of breast cancer (ductal
is the most common subtype, and lobular is the other,
but there are even subtypes of the subtypes), your age
and menopausal status, the apparent size of the tumor,
your medical history, and any pertinent abnormalities
noted on a thorough physical exam, findings on mammogram
and possibly additional imaging studies, and some
molecular characteristics of the cancer (you might think
of these as the “fingerprint” of the cancer), primarily
the estrogen receptor (ER) and HER2 status. For some
women, an additional assay called the
OncotypeDX Recurrence Score
may be ordered as well.
All these elements should be considered by your
surgeon. At DeKalb Surgical, many patients are
offered a Roundtable Consultation as soon as the
diagnosis of cancer is made. At this unique
meeting, a multidisciplinary team of doctors and our
nurse navigator will all meet together with you
simultaneously, in order to come to a unified treatment
plan, customized to your specific situation, to offer
you the greatest likelihood of a cure. Since we have
developed a variety of effective weapons for breast
cancer, including surgery, radiation therapy, hormonal
treatments, and chemotherapy, we want the doctors who
specialize in each of the treatment modalities to meet
and work together to recommend the best sequence of
treatments. We don’t have to use all of these
modalities in every case, but it is best to decide up
front, what the best plan would be, with input from the
entire team, including you, the patient.
In some cases, it may be best to undergo chemotherapy
first, to shrink down the tumor,
and then follow with the surgery to remove any remaining
cancer cells. An advantage of this sequence is that we
can see that in your specific case, the selected
chemotherapy is effective, since we will be able to see
that the cancer, if it’s palpable, actually shrinks
during treatment. In some cases, we even may see that
the chemotherapy is so effective, that when the surgery
is done, ALL the remaining cancer has disappeared.
These patients have a particularly good prognosis.
At DeKalb Surgical, we have available many clinical
trials for patients with breast cancer. Clinical
trials allow us to offer tomorrow’s breast cancer
treatments today. These trials often include newly
approved drugs, which have shown benefit in more
advanced breast cancers, and now are being tested in
women with breast cancers that are more contained (ie, a
lower stage). Or they may be testing a less radical
method of giving the usual radiation therapy to the
breast after surgery. Other trials are proving that
hormonal treatment (which is much easier to tolerate
compared to chemotherapy) is effective in shrinking
tumors before surgery. Not all women are candidates for
clinical trials, but studies have shown that women who
participate in clinical trials tend to have better
outcomes than those who don’t go on a trial.

Is an MRI better than a mammogram for finding breast
cancer?
This
is one of those questions that has a very complex
answer, and the answer may change over the next few
years. MRI stands for “Magnetic Resonance Imaging”,
and is a very sophisticated method of viewing anatomy in
the body. It probably first found a valuable niche in
medicine for evaluating the back part of the brain,
where CAT scans sometimes were lacking in the desired
detail. As time has passed, MRI has been applied to
virtually all body parts, and now has many daily uses,
particularly in evaluating joints and other
musculoskeletal abnormalities, particularly the spine,
and the pelvis and back part of the abdomen. The breast
has been evaluated with MRI as well, and no doubt will
continue to have important applications. But doctors
are not yet agreed as to how best to utilize MRI for
breast problems.
The benefit of MRI in breast problems is its
extremely high sensitivity, which means that it
can show a very high level of detail, and some hidden
cancers (a very small percentage) will not be seen with
any other imaging study. The down side of MRI
has to do with its relatively low specificity,
meaning that not everything it “sees” is bad.
With screening mammograms, less than 10% of women will
have abnormalities that require more evaluation, and of
all the women who have a cancer hiding somewhere in
their breast, about 95% of them will be in that small
10% group. So mammography does a very good job of
sorting out which women have silent cancers, but it does
not find 100% of the cancers. With mammography, we find
1 cancer out of about every 5-6 women for whom we
recommend a biopsy.
With MRI, about 25% of women will have abnormalities
that require more evaluation, and in many cases, there
will be two, three, or even more abnormalities that
might require a biopsy. Of all women with a cancer
hiding in their breast, about 98% will be in that group
of 25%. But you can easily see that the number of women
undergoing biopsies is 2½ times that required based on
the mammograms. There are a few more cancers found,
but it is hard to decide whether it’s worth the cost,
inconvenience, and anxiety for all the women who don’t
have cancer, who now are undergoing biopsies.
At DeKalb Surgical, MRI is used in selected cases,
primarily in women who are already diagnosed with breast
cancer.
In addition, women who have a distinctly higher breast
cancer risk, due to strong family history (eg, either a
documented carrier of one of the BRCA genes, or two
immediate family members with breast cancer, etc.), may
be screened with MRI. In cases where the likelihood of
developing a cancer is extremely high, the use of MRI,
even with its low specificity, makes more sense. (If
you are interested in more information, here is a
table put out by the American
Cancer Society in 2007 that lists their
indications for using breast MRI, and a
link to the full article
from which it came.)
As I said above, the role of MRI is evolving, so our use
of MRI may also change as time goes on, and as more data
is published about the specific situations which may
benefit from its use.

BREAST CYSTS
My doctor says I just have a cyst in my breast?
What causes cysts? Should I have it removed? Should it
be drained with a needle? Will it come back?
Breast
cysts are very common. They are frequently quite large,
and often a bit tender. They may seem to have popped up
overnight, as a very large lump, the size of a grape or
larger. Although we don't know why they occur
specifically, it seems they develop as a response to the
normal hormone variations that occur through the monthly
menstrual cycle. Sometimes they will go away on their
own as quickly as they come, but often they remain for
some time.
Cysts can be classified as "simple" or "complex". An
ultrasound is especially helpful in evaluating cysts; in
fact, if a lump has all the characteristics of a simple
cyst on ultrasound, it can be safely "left alone". But
when it can be clearly felt, and doesn't go away, it may
be best to drain it with a needle. This is simple to
do, and it can relieve any tenderness. What's more,
there is nothing more reassuring about a new lump in
your breast than to make it disappear!
Cysts can come back, but most do not. Some women tend
to develop new cysts over and over, and some women
develop so many cysts that it seems impossible to try to
drain all of them. This situation is challenging,
because it makes it hard to decide if there may be a
"new" lump hiding in the background of all the cysts. In
such cases, it may be best to plan to have your breasts
checked by a physician more frequently, perhaps every
3-6 months. Though this is no guarantee of finding any
beast cancer early, it should help. Having lots of
cysts does not appear to increase your chances of having
breast cancer; it just makes it harder to check.

I had a cyst drained, and the fluid looked green.
Should the fluid be tested for cancer?
In
years past, doctors routinely sent cyst fluid to be
analyzed for cancer. But it turns out that the
information obtained is not really helpful in deciding
what to do, so most doctors have stopped doing this
routinely. There may still be situations in which cyst
fluid analysis is helpful. This may include cases in
which the fluid is crystal clear, bloody, in cases where
the cyst looks unusual on ultrasound, or in a patient
who has an especially high risk of cancer.

My teenage daughter found a lump in her breast.
What should we do?
It
is very rare for lumps in teenagers to be cancer, but it
should still be checked out by a physician. In most
cases, it is a benign growth called a fibroadenoma,
which is not cancer, and except for rare cases, will not
turn into cancer. If left alone, they usually will
eventually go away (regress), but this process may take
years.
Fibroadenomas usually have very typical features on
ultrasound, and they have a very typical rubbery feel,
and can be "pushed around" in the breast tissue very
easily, so your physician may be quite certain that
your lump is a fibroadenoma even without a biopsy. But,
a biopsy is very simple to do, using a "fine needle" or
a "core biopsy", so if you or your doctor have any
anxiety about it, a biopsy or excision should
definitely be done.
Sometimes it may make more sense to just remove the lump
rather than do a biopsy. A lump brings with it a
certain amount of anxiety even if a biopsy is "benign".
If you feel that leaving the lump in would cause you too
much anxiety, even if benign, then you and your doctor
may want to skip the biopsy and just remove it.
There is no one in my family who has had breast cancer,
so my chances of getting breast cancer are very low
aren't they?
Don't assume that you won't get breast cancer just
because it doesn't run in your family! Most breast
cancers are not inherited, meaning that any
female is at risk. If you have a lump in your breast,
or if you have a suspicious finding on your mammogram,
it must be evaluated carefully, regardless of whether
cancer runs in your family.

I have some drainage from my nipple. Is that
normal?
There
are different types of nipple discharge, some of which
are of little concern, and others which are suspicious.
Many women may see a little milky, or slightly greenish
discharge from the nipples at times. It might be seen
when the breast is massaged or the nipple is squeezed or
stimulated, and may be seen from more than one of the
ducts on the nipple. This type of discharge is
considered normal. If you notice tis type of drainage
from your nipples when you squeeze them, it's probably
best to just stop squeezing them.

My mother had breast cancer. Does that mean I will
get breast cancer?
If
someone in your immediate family has been diagnosed with
breast cancer, then your risk of developing breast
cancer is increased by about a factor of 2. If there
are more than one with breast cancer in your family,
your risk goes up further, especially if the cancers
occurred at a young age (younger than 40).
Although most breast cancers are not primarily due to
genetic factors (related to family history), there is a
group of women who carry a gene that carries with it an
extremely high risk for developing both breast and
ovarian cancer. These genes are called the BRCA1 and
BRCA2 genes. These gene mutations can be identified by a
blood test, but the cost is over $2000 currently. Most
women do not need to have this test done. But it is
usually recommended for women who have two or more young
family members with breast cancer, or if there is also a
family history of ovarian cancer. Each patient
considered for the test must be counseled about what the
test involves, and what ae the implications of the test
results. If you want more information, please contact
our office. The genetic testing and counseling is
available through the Kann Cancer Center at DeKalb
Medical Center.

Is there anything I can do to prevent getting breast
cancer?
We
do know something about risk factors for breast cancer.
Breast cancer incidence is higher in patients who are
overweight, those who drink moderate to high amounts of
alcohol daily, and those who consume a diet high in
saturated fats. There is also a higher incidence in
those who have early onset of menstruation, those who
have no full-term pregnancies until late in life, or
those who never have any pregnancies. Also, for those
with children, breast feeding appears to decrease the
incidence of breast cancer.
Most women will not want to base their family planning
on decreasing their cancer risk, but it's at least
helpful to understand these potential implications. But
some basic preventive life styles make sense for most
everyone, namely, avoiding saturated fats as much as
possible, abstaining from alcohol, and maintaining an
ideal body weight. Other good life style measures in
general include complete abstinence form tobacco
products, a diet high in fiber, and a regular exercise
program.

How can I determine how high my risk of breast cancer
is?
We can give an estimate of a woman's risk of developing
breast cancer based on several factors such as family
history, prior breast biopsy results, age at onset of
menstrual periods, etc. One popular "model" for
quantifying this risk is called the Gail model. By
"plugging in" all the pertinent information, a
calculation of the 5-year and lifetime risk can be
made. For the "no risk" women, her 5 year risk would be
about 1%, meaning that if there were 1000 women with no
risk factors, in five years, approximately 10 of them
would have developed breast cancer. A woman who has one
or more risk factors, such as family history, no
pregnancies, etc, her 5 year risk may be 1.5%, or 2.5%
or higher. This would mean that in a group of 1000
women with all those same risk factors, 15 or 20 would
develop cancer over the next five years.
You may want to look at a similar
risk calculation tool
at the National Cancer Institute website, where you
can do your own calculation.
Lifetime risk for a woman with no risk factors would be
in the range of 10%, meaning that 100 of 1000 similar
women would develop breast cancer sometime during their
lifetime. For women with one or more risk factors, their
lifetime risk may be 15% or perhaps as high as 50%.
If my risk of developing breast cancer is high as
calculated by the Gail model or other risk assessment
tool, is there anything I can do about it?
In 1998, a landmark study was published regarding the
use of tamoxifen in the prevention of breast
cancer. About 13,000 women were enrolled in this five
year trial, comparing tamoxifen to a placebo (sugar
pill). The incidence of breast cancer development over
about five years was decreased by about 50%. In the
placebo group, about 20 out of 1000 women developed
cancer, whereas only about 10 out of 1000 women
developed cancer in the tamoxifen group. These results
are dramatic, in that this the first ever drug study to
demonstrate the ability to prevent breast cancer from
developing in the first place.
If a women chooses to take tamoxifen for prevention, it
must be taken for a total of five years. One must be
aware that there are some potential undesirable side
effects. There were a few more cases of endometrial
cancer when taking tamoxifen, and there were more women
with blood clot problems. And there may be side effects
of hot flashes, vaginal discharge, cataract formation,
and depression. But for some women the benefits may
clearly outweigh the risks.

I have heard that Evista (raloxifene) can also decrease
my risk of getting breast cancer. Is this true?
Raloxifene is a drug that was initially approved for the
prevention of osteoporosis. In the study which was
conducted to look at its effect in osteoporosis, it was
noted incidentally that there were fewer women diagnosed
with breast cancer when taking raloxifene.
On the basis of these findings, a large trial was
conducted a few years ago, including almost 20,000
women, which compared the use of Evista (raloxifene) to
tamoxifen for the prevention of breast cancer in women
who were at higher than average risk for developing
breast cancer. This was called the STAR trial
(Study of Tamoxifen and Raloxifene). The results
were published in 2006, and showed that Evista also
decreased the incidence of breast cancer over a 5 year
period. It is important to understand the size of the
benefit. These women had an average estimated risk of
about 4% for developing breast cancer over the next 5
years. This means that out of 100 women in the trial,
only 4 would be expected to be diagnosed with cancer in
5 years. But in the general population only 1 or 2 out
of 100 will develop cancer in 5 years, so the risk is
double or more. Now in the study, with 5 years of
either tamoxifen or Evista (raloxifene), only about 2
out of 100 women were diagnosed with breast cancer over
5 years, so the drugs both decreased the incidence of
cancer by half. While this is really good, the benefit
is limited to only 1 or 2 women out of 100 who take it,
at least over the first 5 years. It seems that the
higher one’s risk is, the more attractive these drugs
become as preventive treatment. You can find more
information at the
National Cancer Institute
website about this trial. Another
informative NCI site can be viewed

New Test Predicts Response to Chemotherapy for Women
with Early Breast Cancer.
The
diagnosis of breast cancer is a very frightening event
for any woman. It is accompanied by many fears and
anxieties, especially anxieties about the need for
chemotherapy, and the fear that the cancer will come
back. These concerns arise for many women despite that
fact that cancer is most often diagnosed in its early
stages, when the risk for recurrent disease is fairly
low. A new test is available that will help women
and their doctors in predicting their risk for
recurrence, and to determine if their cancer would
respond to chemotherapy.
The new test, called the OncotypeDX test, is
performed on tissue from the initial biopsy or
lumpectomy specimen. It uses the unique genetic
profile of each woman’s breast cancer to make an
accurate prediction about whether the cancer will
recur. It measures an array of genes that are known to
be associated with more aggressive tumors. The test has
been shown to be much more powerful than current
predictive methods, which are based on “clinical
staging”, which is based on the size of the tumor and
the status of the lymph nodes.
This OncotypeDX test has been studied in a large group
of women who had participated in two large national
breast cancer clinical trials through the National
Surgical Adjuvant Breast and Bowel Project (NSABP)
several years ago. All of these women had early stage
breast cancer at diagnosis, and all were treated in a
similar fashion, with tamoxifen. The OncotypeDX test
was performed on the initial tissue specimens for all
these women. The women were then grouped according to
the OncotypeDX test results.
All women had been followed for at least 10
years, so it was known who had recurrent cancer.
For the group as a whole, there were 15% who had
recurrence within the first ten years after diagnosis.
Using the OncotypeDX test, this group could be split
into 3 sub-groups, one whose recurrence risk was
extremely low, at 7%, a second group with an
intermediate risk, and a third group whose recurrence
risk was quite high, at 31%, despite being classified as
“early stage” by our current criteria. About half of
the women were in the low recurrence risk group. The
researchers concluded that the test is highly
prognostic for this group of breast cancer patients,
independent of treatment.
The test was also studied to see if it could predict
who would benefit from receiving chemotherapy.
Currently, many women with early stage breast cancer are
advised to receive chemotherapy, in a “one size fits
all” fashion, even though only a very small number are
actually going to benefit. Based on current clinical
staging, there is no simple way to decide which women
would not benefit from chemotherapy. In other
words, we overtreat many women with chemotherapy, for
lack of being able to distinguish which women will
actually benefit.
Using the OncotypeDX test, 50% of the women, all with a
low Recurrence Score, had no benefit from
receiving chemotherapy. Stated another way, if the
Recurrence Score is low, the risk of recurrence is
extremely low, and receiving chemotherapy makes no
difference in the outcome. On the other hand, in the
remaining 50% of women with an intermediate or high
recurrence score, there a much more dramatic benefit
from receiving chemotherapy, especially with a high
Recurrence Score. Incorporation of this test into the
decision process allows the doctor to individualize
treatment based on the “fingerprint” of the patient’s
cancer. Approximately 50% of women with early breast
cancer can thus avoid the toxicity that comes with
receiving chemotherapy.
This exciting new study was reported at the annual San
Antonio Breast Cancer Symposium held in December 2004
and subsequently published in the New England Journal of
Medicine. The test currently is only indicated for
patients with breast cancer that has not spread to the
lymph nodes, and also is “positive” for estrogen
receptors. The test is available for women at
DeKalb Medical Center. Most insurance companies cover
the cost of the test. It is expected that in the near
future the test will be validated in women with more
advanced breast cancer, potentially sparing additional
women the toxicity of chemotherapy. There is already
data showing that OncotypeDX is predictive of the
benefit of chemotherapy even in women with positive
lymph nodes, but its use in this setting is not yet
considered appropriate outside of research settings.
Use of the test may also eventually accelerate our
ability to identify unique molecular targets in breast
cancer, allowing for even greater precision and
individualization in treatment planning.
As the use of this test has expanded, there has been a
need to decide how best to treat those women who fall
into the “Intermediate” Recurrence Score group.
Currently, most oncologists would recommend chemotherapy
for many of these patients, though the data so far
appears to show no real difference in outcomes for women
whether they have chemotherapy or not. There is a
large national clinical trial underway to study this
further. It is called the TAILORx trial (Trial
Assigning IndividuaLized Options
for Treatment (Rx)). In this trial, women with a
low Recurrence Score are treated with hormonal therapy
only, and women with a high Recurrence Score are treated
with chemotherapy followed by hormonal therapy.
Patients with an Intermediate Recurrence Score are
randomized either to receive hormonal therapy alone, or
combined with chemotherapy. You can get more
information about this trial from the surgeons at DeKalb
Surgical, or you may visit this
NCI website for
more details.
