Do You Need A BRCA Test?
What is BRCA testing?
BRCA1 and BRCA2 are human genes that belong to a class of genes known as tumor suppressors. Mutation of these genes has been linked to hereditary breast and ovarian cancer, and the risks of developing breast and/or ovarian cancer is greatly increased if the BRCA1 or BRCA2 mutations have been inherited.
Both men and women who have harmful BRCA1 or BRCA2 mutations may be at increased risk of other types of cancer.
