| Breast cancer
is the disease many women fear the most. It is the second
most common cancer among women, with about 192,000 new
cases each year. It remains the leading cause of death
of women between age 40 and 55. While known primarily
as a woman's disease, men also develop breast cancer.
The good news is that survival rates today are higher
than ever due to advances in diagnosis and treatment.
At the Vejthani Woman Center, emphasis is placed on screening
for early detection, more effective and less toxic therapies,
patient education and research that explores the causes,
biology and behavior of the condition for future prevention
and treatment strategies.
The Woman Center works to heal the whole person, both
your physical and emotional being. We provide specialized
services including individual counseling as well as support
groups that focus on every stage that you and your family
may experience and where patients share their stories.
Signs and Symptoms
Breast cancer begins with abnormal cells developing in
breast tissue. It can be confined to the breast or may
spread beyond your breast or into other parts of your
body. The most common type of breast cancer begins in
the ducts designed to carry milk to the nipple. But cancer
also may occur in the small sacs that produce milk, called
lobules, or in other breast tissue. Breast cancer varies
widely and the treatment options are selected to match
your individual needs.
Breast cancer may occur in several different forms, such
as the five types below:
• Breast Cancer in
Situ, DCIS and LCIS -- Many breast cancers detected early,
typically by mammography, are classified
as breast cancer in situ or noninvasive cancer. These
early cell changes may develop into invasive breast
cancer. Two types of breast cancer in situ are:
o
DCIS (ductal carcinoma in situ) means that abnormal cells
are found only in the lining of a milk duct of the
breast. These abnormal cells haven't spread
outside the duct. There are several types of DCIS. If
not removed,
some may change over time and become invasive cancers,
while others may not. DCIS is sometimes
call intraductal carcinoma.
o
LCIS (lobular carcinoma in situ) means that abnormal cells
are found in the lining of a milk lobule. Although LCIS
is not considered to be actual breast cancer at this noninvasive
stage, it is a warning sign of an increased
risk of developing invasive cancer. LCIS sometimes is
found in a biopsy for another lump or unusual
change detected on a mammogram.
• Invasive Breast
Cancer -- These cancer cells form in the ducts or the
milk lobules and spread to the breast tissue around
them. Tumors can be found during a breast exam or through
screening, such as a mammogram. The size of
the tumor, what it looks like under the microscope and
whether it has spread to the lymph nodes determines the
severity of the cancer, the therapies and the difference
treatments will make.
• Metastatic Breast
Cancer -- Metastatic cancer begins in the breast, but
spreads outside the breast through the blood
or lymph system to other organs. Women usually develop
metastatic disease in the months or years following
the diagnosis of breast cancer. This cancer most commonly
spreads beyond the breast to a patient's bones,
lung, liver and brain.
• Locally Advanced
Breast Cancer -- Inflammatory breast cancer is a rare
but very serious and aggressive type of breast
cancer. The breast may look red and feel warm. A patient
may see ridges, welts or hives on the breast or its skin
may look wrinkled. It is sometimes misdiagnosed as an
infection.
• Recurrent Breast
Cancer -- Recurrent disease means that the cancer has
come back or recurred after treatment. It may
come back in the breast, in the soft tissues of the chest
or chest wall, or in another part of the body.
Symptoms
Early breast cancer usually doesn't cause pain. In fact,
when breast cancer first develops, there may be no symptoms
at all. But as the cancer grows, it may cause changes
that you should watch for:
• A lump or thickening
in or near the breast or in the underarm area
• A change in the
size or shape of the breast
• Nipple discharge
or tenderness, or the nipple pulled back (inverted) into
the breast
• Ridges or pitting
of the breast, making the skin look like the skin of an
orange
• A change in the
look or feel of the skin of the breast, areola or nipple
such as warmth, swelling, redness or scaliness
Diagnosis
If cancer is found in your breast, your doctor will want
to know the stage or extent of the disease. Staging is
a careful attempt to find if the cancer has spread and,
if so, to what parts of the body. Your doctor may use
blood and imaging tests to learn the stage of the disease.
Treatment decisions depend on these findings. Read Staging:
Specific Patterns of Breast Cancer to learn more about
the staging system.
The first step in the work-up of breast disease is usually
a physical exam by a doctor or nurse practitioner. Mammography
and ultrasound may be important additions to the physical
examination. On the basis of these evaluations, the decision
may be made to confirm a clinical impression with a tissue
biopsy.
Imaging
Imaging is an important component used to diagnose breast
cancer and to evaluate the stage and extent of disease
in breast cancer patients. Three major types of imaging
are used in this capacity: mammography, ultrasonography
and breast magnetic resonance imaging (MRI). Based on
these exams, your physician may determine that no treatment
is necessary or may recommend further tests or therapy.
• Screening
Mammography -- A mammogram is a low-dose X-ray
of the breast. This is the best test we have to screen
women for breast cancer. A Screening Mammogram consists
of two "pictures" of each breast. If an area
on the mammogram looks suspicious or is not clear, additional
mammograms with different views may be needed. Annual
screening mammography is recommended for all women over
40 years old.
• Diagnostic
Mammography -- This is a mammogram used for problem-solving,
rather than for screening. For instance, if a patient
has a lump in her breast, a directed investigation of
that area is performed. This is also done when a particular
finding in the breast is being followed over time. A diagnostic
mammogram is tailored to the patient's case and is carefully
monitored by a radiologist, who interprets the images
and determines whether there is any need for further tests.
• Ultrasonography
-- Using high-frequency sound waves, ultrasonagraphy
can often show whether a lump is solid or filled with
fluid. This exam may be used along with Diagnostic Mammography
or MRI to answer questions about a specific area of the
breast. Because it uses sound waves instead of X-Rays,
ultrasound provides information that is different and
often complementary to the mammogram.
• Breast MRI
-- Magnetic resonance imaging (MRI) can be used to look
specifically at the breast. Each exam produces hundreds
of images of the breast, cross-sectional in all three
directions (side-to-side, top-to-bottom, front-to-back),
which are then read by a radiologist. It is non-invasive
and no radioactivity is involved. The technique is believed
to have no health hazards in general. The hope is that
such non-invasive studies will contribute to our progress
in learning how to predict the behavior of tumors, and
in selecting proper treatments. Breast MRI is an evolving
technology and should not replace standard screening and
diagnostic procedures, such as clinical and self-exams,
mammogram, fine needle aspiration or biopsy. To learn
more about breast MRI, please visit the UCSF Breast MRI
Web site.
Biopsy
One way to find out if a breast lump or abnormal tissue
is cancer is by having a biopsy. During a biopsy, a surgeon,
a pathologist or a radiologist removes a portion or all
of the suspicious tissue. The suspicious tissue is examined
under a microscope by a pathologist who checks for cancer
cells and makes the diagnosis. The following are different
types of biopsies as well as how you can best prepare
yourself for each of them. The following are different
types of biopsies.
• Fine Needle
Aspiration (FNA) Biopsy -- FNA samples a woman's
lump using a thin small needle that leaves a mark no bigger
than a needle stick from a blood test. FNA often allows
us to diagnose a lump within two to three days. Read Fine
Needle Aspiration Biopsy for Breast Cancer Diagnosis to
learn more about the procedure and what to expect.
• Stereotactic
Core Biopsy -- This procedure was developed as
a less invasive way to obtain tissue samples for diagnosis.
It involves removing tissue with a biopsy needle while
your breast is compressed in a way similar to a mammogram.
This biopsy requires less recovery time than surgery and
causes no significant scarring. You and your physician
and radiologist may consider this procedure if there is
an abnormality on a mammogram that cannot be felt. Your
radiologist decides if this procedure is technically possible
for your condition and your physician decides if it's
appropriate for your situation. Read Stereotactic Core
Biopsy for Breast Cancer Diagnosis to learn more about
the procedure and what to expect.
• Needle (Wire)
Localization Biopsy -- This type of biopsy involves
the use of a needle and wire to locate the abnormal tissue
and surgery to remove it. Needle localization is performed
when you have an abnormality on a mammogram that cannot
be felt. It is an outpatient biopsy that is done in two
steps on the same day. Read Needle (Wire) Localization
Biopsy for Breast Cancer Diagnosis to learn more about
the procedure and what to expect.
Treatment
Current treatments for women with breast cancer include
surgery, radiation therapy, chemotherapy and hormonal
therapy. Treatment methods are classified as local or
systemic. Local treatments — such as surgery and
radiation therapy — remove, destroy or control cancer
cells in a specific area. Systemic treatments —
such as chemotherapy and hormonal therapy — destroy
or control cancer cells throughout the body. Depending
on your condition, you may receive a single treatment
or a combination of therapies given at the same time or
in succession.
Surgery
Surgery is a common treatment for cancer and several types
may be used from lumpectomy to breast reconstruction:
• Lumpectomy
-- In this procedure, a surgeon removes the breast cancer
and some normal tissue around it. This procedure usually
removes all the cancer with little change in the appearance
of your breast. Typically, the surgeon takes out some
lymph nodes from under your arm to determine if the cancer
has spread. If you have a lumpectomy, you are likely to
have radiation therapy as well. Radiation destroys cancer
cells that may not have been removed by surgery.
• Partial
or Segmental Mastectomy -- Depending on the size
and location of the cancer, this procedure can conserve
much of the breast. The surgeon removes the cancer, some
breast tissue, the lining over the chest muscles below
the tumor and usually some of lymph nodes under the arm.
In most cases, radiation therapy follows.
• Sentinel
Lymph Node Disection -- One or more of your sentinel
lymph nodes are removed in this procedure. To locate a
sentinel node, the surgeon injects a blue dye (isosulfan
blue) into the skin where the breast cancer is or was.
The blue dye is picked up by the lymphatic vessels and
travels to a sentinel node. A lymph node is removed and
sent to pathology, where it is examined. The sentinel
lymph node is believed to most likely contain disease
if the cancer has spread from the breast to the lymph
nodes. Other lymph nodes may or may not be removed, depending
on your situation. This procedure typically takes about
an hour.
• Modified
Radical Mastectomy -- In this procedure, a surgeon
removes the breast, some of the lymph nodes under the
arm, and the lining over the chest muscles, and sometimes
part of the chest wall muscles.
• Radical
Mastectomy -- The surgeon removes the breast,
chest muscles and all the lymph nodes under the arm in
a radical mestectomy. This was the standard operation
for many years, but now is performed only when a tumor
has spread to the chest muscles.
• Breast Reconstruction
-- Breast reconstruction, or surgery to rebuild a breast,
is often an option after the removal of a breast. Health
insurance plans in California pay for this surgery, including
surgery to make both breasts similar in shape and size.
A reconstructed breast will not have natural sensation,
but can have a natural appearance. The best cosmetic results
are achieved with immediate reconstruction, performed
at the same time as the mastectomy. The choice regarding
reconstruction is based on personal preferences and will
not affect outcome.
Radiation Therapy
Radiation therapy is the use of high-energy rays or particles
to treat disease. It works by killing tumor cells or inhibiting
their growth and division. Years of study by radiation
oncologists have led to the widespread use of effective,
tolerable doses of radiation. It is used to treat early
stage breast cancer along with surgery. It may be used
in more advanced breast cancer to control the disease
or to treat symptoms such as pain.
To learn more, read Radiation Therapy for Breast
Cancer.
Chemotherapy
Chemotherapy uses drugs to kill cancer cells. For breast
cancer, it is usually administered as a combination of
drugs given orally or by injection. Chemotherapy enters
the bloodstream and travels throughout your body. The
treatment is most commonly used to decrease the chance
that cancer will recur after surgery, shrink breast cancer
after surgery when the tumor is large or if it is inflammatory,
and to control metastatic breast cancer which has spread
to other organs in the body.
Hormonal Therapy
Hormonal therapies change the hormonal environment in
your body, which impacts the growth and behavior of some
breast cancers. If your breast cancer produces one of
the hormone receptors — estrogen receptor (ER) or
progesterone receptor (PR) — then hormonal therapy
is effective in treating early-stage, metastatic or advanced
breast cancer and preventing recurrence.
