Breast cancer An estimated 12 percent of women in the general population will develop breast cancer at some point in their lives. An estimated 72 percent of women who inherit a harmful BRCA1 mutation and 69 percent of women who inherit a harmful BRCA2 mutation will develop the disease by age Breast cancer. Researchers have identified more than 1, mutations in the BRCA2 gene. Many of these mutations are associated with an increased risk of breast cancer in both men and women, as well as several other types of cancer. These mutations are present in every cell in the body and can be passed from one generation to the next. Women who have a BRCA1 or BRCA2 gene mutation have medical options to help lower their risk of breast cancer: Risk-lowering drugs (tamoxifen or raloxifene). Prophylactic mastectomy.
