There are many inherited genetic mutations that can increase the likelihood of breast cancer. Two of the most well-known genes are breast cancer gene 1 (BRCA-1) and breast cancer gene 2 (BRCA-2). These genes greatly increase the risk of breast and ovarian cancer.
What are BRCA-1 and BRCA-2?

What Cancers are Linked to Mutations in BRCA-1 & BRCA-2?
The most common cancers strongly associated with these mutations are breast and ovarian cancer. Anyone with these
