Breast
Cancer Prevention
The risk of breast
cancer increases gradually as a woman gets older. This disease is uncommon
in women under the age of 35.
All women age 40 and
older are at risk for breast cancer. However,
most breast cancers occur in women over the age of 50, and
the risk is especially high for women over age 60.
At this time, there
is no way to prevent breast cancer. A woman's best strategy is to reduce
her known risk factors whenever possible, by increasing physical activity,
reducing alcohol intake, and avoiding obesity. Also, recent clinical research
has provided important information on ways that women at very high risk
can further reduce their risk of breast cancer using the anti-estrogen
drug tamoxifen.
Who
Is at Risk for Breast Cancer?
Simply being a woman and getting older puts you at some risk for breast
cancer. Your risk for breast cancer continues to increase over your lifetime.
Several known factors can further increase your risk for breast cancer.
Most women who get breast cancer have no known risk factors such as a
family history of the disease.
Talk
to your doctor about the known risk factors for breast cancer.

What Should You Do?
Women in their fifties need evaluate their family history of breast
cancer to rule out genetic factors. Also, most cases of breast cancer
occur in women during their fifties so it is important to consistently
visit a doctor or health care practitioner for an annual clinical breast
examination and mammogram. It is never too late to begin incorporating
a healthy diet and moderate exercise in an effort to prevent breast cancer.
