Family history is one of the unavoidable genetic risk factors for developing breast cancer. BRCA1 and BRCA2 gene mutations are currently the best-known and most discussed genetic risk factors, but new genetic links are being discovered regularly. In other words, it works in.
About 5% to 10% of breast cancers are thought to be hereditary, caused by abnormal genes passed from parent to child. Most inherited cases of breast cancer are associated with mutations in two genes: BRCA1 (BReast CAncer gene one) and BRCA2 (BReast CAncer gene two).
Breast cancer is a disease in which certain cells in the breast become as hereditary and are associated with inherited gene mutations.
