No. Every woman has some risk of breast cancer. About 80% of women who get breast cancer have no known family history of the disease. Increasing age -- just the wear and tear of living -- is the biggest single risk factor for breast cancer.
For those women who do have a family history of breast cancer, your risk may be elevated considerably, slightly, or not at all, compared to women without a family history of breast cancer. If you are concerned, discuss your family history with your physician or a genetic counselor. You may be worrying needlessly.
