What is BRCA Mutation?

0

A BRCA mutation is an irregularity in the breast cancer (BRCA) gene which can make someone more susceptible to developing breast cancer. BRCA mutations do not guarantee that someone will develop breast cancer, but they make cancer much more likely, and a mutation can be an indicator that certain preventative steps should be taken to reduce the risk and to identify cancer early, if it does emerge. Genetic testing can be used to determine whether or not a defect is present on this gene.
