What Is Breast Cancer?
Breast cancer is the abnormal growth and uncontrollable division of cells in
the breast area. Once the cells begin to grow uncontrollably, they can
invade nearby healthy tissue and destroy them. This process usually begins
with surrounding lymph nodes under the armpit and tissue under the
breastbone and collarbone. It is possible that a tumor may form. Benign
tumors are not cancerous -- they do not strike surrounding tissue and spread
throughout the body. Malignant tumors, however, have the capacity to grow
beyond their original location and into other tissues.
According to the American Cancer Society:

|
Each year, more than 200,000 women in this country learn they have
breast cancer
|

|
Breast cancer is the most common type of cancer among American women
and the second leading cause of cancer death in the United States
(second to lung cancer)
|

|
More women are surviving the disease than ever before, thanks to
advances in diagnosis and treatment, and earlier detection
|

|
Right now, just over 2 million breast cancer survivors are living in
the United States
|
Risk Factors
It has not yet been confirmed why breast cancer occurs, but certain factors
are known to increase the possibility of developing the disease.
|
Controllable risk factors (lifestyle based):
|
|
|

|
Diet: A link between breast cancer and a diet high in fat has
been suggested
|
|
|

|
Physical inactivity: A sedentary lifestyle can be potentially
dangerous to the health, as it increases the risk of developing
different diseases, including breast cancer
|
|
|

|
Obesity: A severely overweight individual is at increased
risk
|
|
|

|
Alcohol consumption
|
|
|
Uncontrollable risk factors:
|
|
|

|
Age: The older a woman is, the higher her chance she has of
developing breast cancer
|
|
|

|
Race: White women tend to develop breast cancer more than
African-American women. However, African-American women are more likely
to die of this cancer because their cancers are often diagnosed later
and at an advanced stage when they are more difficult to treat and cure.
Although it is possible, Asian, Hispanic, and Native American women have
less of a risk of developing breast cancer
|
|
|

|
Family or personal history of breast cancer
|
|
|

|
Early start of menstruation (before age 12)
|
|
|

|
Late menopause (after age 55)
|
|
|

|
Reproductive history: If a woman delivers her first baby
after the age of 30 or never has children, she may face an increased
risk of developing breast cancer
|

Common Symptoms
Breast cancer usually develops without any noticeable symptoms. It is,
however, advisable to perform monthly breast self-examinations, due to the
fact that discovering breast lumps can often be a sign of trouble.
Scheduling an appointment with a doctor is recommended if one of the
following warning signs is experienced:

|
Destroy or slow the growth of cancer cells that have metastasized to
other parts of the body
|

|
Shrink the cancer tumors before surgery
|

|
Relieve symptoms caused by cancer such as pain
|
What Are the Goals of Chemotherapy Treatment?

|
Change in the size or shape of the breast
|

|
Lump or thickening of tissue in the breast or armpit
|

|
Dimpled or pulling of the skin over the breast
|

|
Nipple discharge
|

|
Retraction of the nipple
|

|
Scaliness of the nipple
|

|
Pain or tenderness
|
Screening and Diagnosis
The chance of survival significantly increases when breast cancer is found
early. Performing self breast exams, regular screening mammograms and
clinical breast exams are a good way to participate in the early detection
of breast cancer.

|
Mammogram - A mammogram is a procedure that uses x-rays to
detect changes in breast tissues. It can detect cancer and other tumors
before a woman would be able to feel in her monthly self examination. If
there is history in the family or personal past of the disease, it is
advisable to begin annual mammograms at age 40 or before
|

|
Clinical breast exam - An examination of the breasts
performed by a healthcare professional
|

|
Breast self-exam - Regular breast exams can help women become
familiar with the way their breasts normally look and feel, making it
easier to notice any changes. A few days after a normal menstrual period
is the best time to perform a breast self-exam, when the breasts are no
longer swollen or tender.
|

Stages of Breast Cancer
If a breast cancer diagnosis is made, doctors perform additional tests to
determine the stage of the cancer. At this time, it is also established if
the cancer has spread and exactly how far. Staging the cancer is an
important step for your doctor to perform so he/she can develop an
appropriate treatment plan.
|
Stage 0: This stage is used to describe non-invasive breast cancer.
In other words, there is no evidence of cancerous cells invading neighboring
healthy tissue.
|
|
Stage 1: This is an early stage of invasive breast cancer, but still
confined to the breast. Lymph nodes are not involved in this stage.
|
|
Stage II:
|
|

|
The breast tumor measures less than ¾-inch, and the cancer has
spread to the lymph nodes under the arm; or
|
|

|
The tumor ranges in size from ¾-inch to 2 inches and may have
advanced to nearby lymph nodes; or
|
|

|
The tumor is larger than 2 inches but has not spread to lymph nodes
under the arm
|
|
Stage III: The tumor may be large at this stage, but the cancer is still
confined to the breast and nearby lymph nodes. Stage III is divided into
IIIA and IIIB subcategories:
|
|

|
In Stage IIIA, the tumor in the breast measures 2 inches or less,
the cancer is present in underarm lymph nodes, and the lymph nodes are
attached to each other or to other structures. In other cases of Stage
IIIA breast cancer, the tumor exceeds 2 inches and cancer is present in
the underarm lymph nodes
|
|

|
In Stage IIIB, the tumor may have spread to lymph nodes inside the
chest wall along the breastbone
|
|
Stage IV: This stage includes cancer that has metastasized to other
parts of the body, frequently the bones, lungs or brain
|
|
Recurrent: Cancer that has returned after treatment. The breasts,
chest wall or other parts of the body may be affected in the recurrent stage
|
Common Treatment Options
Thanks to medical advances, patients have more treatment options than ever
before. Breast cancer is incredibly treatable with high survival rates.
Treatment options for breast cancer depend on the type, stage and size of
the tumor. General health and personal preferences also play a role in the
type of treatment a patient will endure. The goal of treatment is to
safeguard healthy tissue while killing the tumor where it originated, as
well as any other cancer cells that have spread throughout the body.
Treatment options include:
Surgery
It is common that patients with breast cancer undergo surgery to remove
the cancerous tissue in the breast. Some axillary lymph nodes (lymph nodes
in the armpit) are also extracted to see if the breast cancer has spread.
Types of surgery include:
|
Wide Excision Lumpectomy - This type of surgery removes the breast
tumor and a small amount of surrounding normal tissue.
|
|
Mastectomy - The surgical removal of the entire breast. There are
three different types of mastectomies:
|
|

|
Simple or total mastectomy - surgeons do not cut away any
lymph nodes or muscle tissue
|
|

|
Modified radical mastectomy - surgeons remove the breast and
some armpit lymph nodes
|
|

|
Radical mastectomy - surgeons remove the breast, axillary
lymph nodes and chest wall muscles under the breast
|
Breast reconstruction surgery can be considered after a mastectomy. A breast
implant may be used to reconstruct the breast at the same time as the
mastectomy, or anytime thereafter.

Radiation Therapy
Radiation therapy is a non-surgical method of treatment of cancer. This
procedure uses penetrating beams of high-energy waves called x-rays or gamma
rays. Radiation destroys tumor cells by destroying their genetic material,
making it impossible for these cells to continue to grow. There are two
types of radiation therapy:

|
External beam radiation therapy: Specialized medical
equipment is used to deliver radiation to the tumor site from outside
the body.
|

|
Internal radiation therapy: Radioactive material is inserted
in the body near the cancer cells (also called implant radiation or
brachytherapy)
|

|
MammoSite Radiotherapy: MammoSite therapy is usually
performed on women who are in early breast cancer stage. Radioactive
seeds are used but are only left in temporarily and taken out after each
treatment. This procedure is completed in five days rather than the
usual six weeks women endure of daily radiation therapy.
|
The type of radiation therapy given depends on the type and stage of the
cancer being treated.
Chemotherapy
Chemotherapy treatment uses drugs to stop the growth of cancer cells, either
by killing the cells or by preventing the cells from dividing. Depending on
the type and stage of cancer, chemotherapy drugs can be taken orally or by
injection. Discussing treatment protocols with a treatment professional is
important to become aware of any possible side effects.
Hormone Therapy
Hormone therapy is a type of treatment that eliminates hormones or blocks
their action and stops cancer cells from growing. Because some hormones can
cause certain cancers to grow, drugs, surgery, or radiation therapy are used
to reduce the production of hormones or block them from working if tests
show that the cancerous cells have receptors.
Breast Cancer in Men
Although it is unusual for men to develop breast cancer, it can be found in
those between 60 and 70 years of age. Breast cancer is an extremely rare
cause of death in men.
