BRCA Breast Cancer Genes

Women who have BRCA breast cancer genetic mutations are just as likely to survive as other women who get breast cancer, according to a new study published in the New England Journal of Medicine. Women with BRCA1 and BRCA2 genes are more likely to get breast cancer. It was also widely believed that those with hereditary breast cancer from BRCA1 mutations had worse outcomes. This new study, tracked two groups of women with breast cancer in Israel, one with the inherited BRCA1 and BRCA2 mutations, and the other without. The researchers found no significant difference in death rates between the two groups. Between 5 and 10 percent of all breast cancers are hereditary and are more likely to occur with women from certain ethnic backgrounds like people of Ashkenazi (central or eastern European) Jewish heritage [one reason why the study was done in Israel].
