Ask the Doctor: Breast Cancer Risk
With Shruti Trehan, M.D.

Q. What can I do to decrease my risk of developing breast cancer?

Thanks to earlier detection and better treatments, the death rates from breast cancer have steadily decreased over the past decade. However, many of the risk factors, such as family history, are beyond your control. Here are some simple lifestyle changes that can decrease your risk:

1. Obesity: Research has indicated an increased risk of developing breast cancer in women who are overweight, especially after menopause.

2. Exercise: This goes hand in hand with weight. Women who exercise on a regular basis, even as little as eleven minutes of activity each day, have a decreased incidence of breast cancer.

3. Diet and Nutrition: At least five and up to nine daily servings of fresh fruit and vegetables are recommended by the American Cancer Society.

4. Smoking: This increases the risk of multiple cancers, including breast cancer.

5. Alcohol: Many studies have associated greater than two drinks a day with an increased risk of breast cancer.

Q. What if I have a strong family history of breast cancer?

Most inherited cases of breast cancer have been associated with the BRCA (Breast Cancer) 1 or 2 genes. You are more likely to have an abnormal breast cancer gene if you have multiple relatives on your mother's or father's side who have had breast, ovarian, or other types of cancers prior to the age of 50.

There are now blood tests available that can determine whether a person has inherited the mutated (abnormal) gene. Testing a patient who has had breast or ovarian cancer for a mutated gene is usually recommend before testing yourself. If you then test positive, this may increase your risk of developing cancer. Special tests such as a breast MRI may detect minute abnormalities. I recommend seeking professional help from a genetic counselor prior to undergoing genetic testing. You may also want to consult with professionals experienced in managing familial breast cancer.

It is important to keep up on your mammograms at least once a year after the age of 40 or more frequently/sooner based on your doctor's recommendations.
