Ms. G. is a 40-year-old woman with two small
children. Like most women, she is concerned about her chances of developing
breast cancer. She asks her doctor about her risks.
Although breast cancer is a worry for most women, Ms. G. is especially worried because of a
family history of breast cancer. Her mother and sister had breast cancers that were diagnosed
at young ages.
A woman with a family history of breast cancer
has a lot of concerns. Among other things, she is thinking of her job, children,
and husband, as well as how her medical insurance and health team will be able
to serve her needs in the future should a crisis arise.
What are the facts about families that have multiple members with breast cancer?
Inherited breast cancer disorders account for a
small minority of breast cancers overall. Genes are the "messages" in
each cell of the body that determine the ultimate design of our bodies. Genes
can be damaged by the environment. Additionally, people can be born with defects
in the genes that remove the body's defenses against cancers. Only in about 10%
of all breast cancer cases is there actually a genetic defect that can be
tested. This means that 90% of breast cancers are due to other causes. In fact,
most cases of breast cancer occur in women who do not have a family history of
breast cancer. A complex interplay between environmental and genetic factors
affect the development of breast cancer, and all the key factors have not yet
been identified.
Younger women generally do not consider themselves to be at
risk for breast cancer. Only 5 percent of all breast cancer cases occur in women under 40 years old. However, breast cancer can strike at any age, and all women should be aware of their personal risk factors for breast cancer. (A risk factor is a condition or behavior that puts a person at risk for developing a disease.)
There are several factors that put a woman at high risk for developing breast cancer, including:
Risk factors include:
A personal history of breast cancer or non-cancerous
breast disease
A family history of breast cancer, particularly in a
mother, daughter or sister
History of radiation therapy Evidence of a specific genetic defect (BRCA1/BRCA2 mutation).
Women who carry defects on either of these genes are at greater risk for
developing breast cancer.
A Gail Index score of at least 1.7% (The Gail Index uses risk factors such as age, family history of breast cancer, age of first menstrual period and first pregnancy, and number of breast biopsies to calculate a woman's risk of developing breast cancer within the next five years.)
An extended use of oral contraceptives (the Pill) later in life is also sometimes considered a factor for developing breast cancer. However, this is still subject to much debate in the medical community.
What Is Different About Breast Cancer in Younger Women?
Diagnosing breast cancer in younger women (under 40 years old) is more difficult because their breast tissue is generally more dense than the breast tissue in older women. By the time a lump in a younger woman's breast can be felt, the cancer often is advanced.
In addition, breast cancer in younger women may be aggressive and less likely to respond to treatment . Women who are diagnosed with breast cancer at a younger age are more likely to have a mutated (altered) BRCA1 or BRCA2 gene.
Delays in diagnosing breast cancer also are a problem. Many younger women who have breast cancer ignore the warning signs -- such as a breast lump or unusual discharge -- because they believe they are too young to get breast cancer.
Many women assume they are too young to get breast cancer and tend to assume a lump is a harmless cyst or other growth. Some health care providers also dismiss breast lumps in young women as cysts and adopt a "wait and see" approach.
Breast cancer is the most common cancer in women and the second most common cause of cancer death in women in the U.S. Symptoms include a lump in the breast or underarm area, nipple pain, change in breast size or shape, an inverted nipple, nipple discharge, and breast skin changes. Treatment may involve chemotherapy, radiation therapy, biological therapy, hormone therapy, or surgery.
Breast lumps in women can have a variety of causes such as breast inflammation, infection, injuries, cancer, and non-cancerous growths. Breast lumps in women are diagnosed with physical exam, mammogram, ultrasound, MRI, and biopsy. Treatment of breast lumps in women depend on the cause.
The breast generally refers to the chest, however, more specifically, to the mammary gland. The mammary gland is a milk producing gland comprised largely of fat. Within the mammary gland is a complex network of branching ducts. The ducts exit from sac-like structures called lobules, which can produce milk in females. The darkened area around the nipple is called the areola. Common medical concerns in regard to the breast include breast lumps, breast cysts, breast cancer, and breast infections.
Inflammatory breast cancer is an accelerated form of breast cancer that is not usually detected by mammogram or ultrasound. Symptoms of inflammatory breast cancer include pain in the breast, skin change in the breast area, bruise on the breast,sudden swelling of the breast, nipple retraction or discharge, and swelling of the lymph nodes.
Lymphedema is a common chronic, debilitating condition in which excess fluid called lymph collects in tissues and causes swelling in them. It is common after a mastectomy, lumpectomy or breast cancer surgery and radiation therapy.
Women's health is an important topic area to guide a woman through the stages of her life, as well as knowing the conditions and diseases that may occur. Educating yourself so that the transitions into different phases of life is key to a healthy, happy, and productive life.
Lifestyle changes, a healthy antioxidant-rich diet, exercise, and weight reduction can help reduce a woman's risk of developing breast cancer. It's important to be aware of how risk factors such as family history, lifestyle factors, breast conditions, radiation therapy, and hormonal factors may influence your chances of developing breast cancer. Mammography and breast self-examinations are crucial steps in breast cancer prevention.
There are many causes of breast lumps. Some of
these causes are harmless, while others can be painful and/or dangerous. Causes
of breast lumps include infections, injuries, non-cancerous growths, and cancer.
Breast cancer is the second leading cause of
cancer-related deaths in women in the United States. Currently, death rates from
breast cancer are declining. The decline in death rates may be due to a
combination of earlier detection and better screening as well as improved
treatments. While most breast lumps are harmless (benign), every breast lump
should be evaluated by a doctor to exclude or establish a diagnosis of cancer.
