WebIt typically takes more than one gene mutation for a cell to become a cancer cell. But when someone inherits an abnormal copy of a gene, their cells already start out with one mutation. This makes it easier (and quicker) for other mutations to happen, which can lead to a cell becoming a cancer cell. WebIf you have a fault (mutation) in one of the BRCA genes, your risk of developing breast cancer and ovarian cancer is greatly increased.
