Should you be tested to see if you have the breast-cancer gene? Here, experts from the federal Centers for Disease Control tell you what you need to know: 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.
