In the general population, between one in 300 and one in 800 individuals carry a BRCA1 or 2 or mutation.1 For individuals of Ashkenazi Jewish ancestry, one in 40 individuals carry a BRCA1 or 2 mutation. What percentage of breast and ovarian cancers are caused by BRCA1 or BRCA2 mutations? 5 percent-10 percent of all breast cancer. Up to
