A harmful variant in BRCA1 or BRCA2 can be inherited from either parent. Each child of a parent who carries any mutation in one of these genes has a 50% chance (or 1 in 2 chance) of inheriting the mutation. Inherited mutations—also called germline mutations or variants—are present from birth in all cells in the body.
Is raloxifene effective for BRCA1 and BRCA2 mutation carriers?
Studies have not examined the effectiveness of raloxifene in BRCA1 and BRCA2 mutation carriers specifically. Oral contraceptives (birth control pills) are thought to reduce the risk of ovarian cancer by about 50% both in the general population and in women with harmful BRCA1 or BRCA2 mutations (27).
