~15–20% of ovarian cancers are hereditary. BRCA1 carriers have up to 44% lifetime risk. Polygenic risk accounts for additional heritability.
How Genetic Is Ovarian Cancer?
Ovarian Cancer involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 39%, though no single gene determines outcome on its own.
Key genes associated with Ovarian Cancer: BRCA1 BRCA2 RAD51C. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Ovarian Cancer?
Family history can be informative for Ovarian Cancer, but its predictive power is limited because many genes — each with small effects — combine with environmental influences. A family history of the condition may prompt earlier or more frequent screening.
