"If you have close relatives with breast or ovarian cancer, you may be at higher risk for developing these diseases. Does your family health history put you at higher risk? Would you benefit from cancer genetic counseling and testing?Each year, over 200,000 women in the United States are diagnosed with breast cancer and more than 20,000 are diagnosed with ovarian cancer. About 3% of breast cancers (about 6,000 women per year) and 10% of ovarian cancers (about 2,000 women per year) result from inherited mutations (changes) in the BRCA1 and BRCA2 genes that are passed on in families. Inherited mutations in other genes can also cause breast and ovarian cancer, but BRCA1 and BRCA2 are the genes most commonly affected. Although breast cancer is much more common in women, men with BRCA1 or BRCA2 mutations are more likely to get breast cancer than other men. BRCA mutations also increase the likelihood of getting pancreatic cancer and, in men, high grade prostate cancer. Knowing your family health history can help you find out if you could be more likely to develop breast, ovarian, and other cancers. If so, you can take steps to prevent cancer or to detect it earlier when it may be more treatable..."
