Then, if you want a more in-depth evaluation, sign up for the National Cancer Institute's Breast Cancer Risk Assessment Model. Women have a far greater risk of breast cancer than men. The disease is about 100 times more common among women than men. Women with these inherited mutations also have an increased risk for developing cancer of the ovary. Risk is also higher among women whose close blood relatives have this disease.
Blood relatives can be from either the mother's or father's side of the family.
The risk of developing breast cancer increases with age. About 77 percent of women with breast cancer are over the age of 50 at the time of diagnosis. Women who had their first full-term pregnancy after age 30 and women who have never borne a child have a greater risk of developing breast cancer. Women who have had breast biopsies have an increased risk of breast cancer, especially if the biopsy showed a change in breast tissue known as atypical hyperplasia. These women are at increased risk because of whatever prompted the biopsies, NOT because of the biopsies themselves.
