Those with a BRCA2 mutation face up to a 69% risk of breast can.cer and a 17% risk of ovarian cancer.
These mutations can be inherited from either parent and are passed down in families. That’s why a family history of either ca.ncer can raise your own risk—even if no one in your family has had both.
Family History Matters
If your mother, sister, grandmother, or aunt has had breast or ovarian can.cer (especially at a young age), your own risk may be higher. This is true even if they had only one type. In some cases, multiple generations may be affected without knowing the cause was genetic.

Women with a strong family history may consider genetic counseling and testing for BRCA mutations
