Melanoma is a skin cancer arising from melanocytes. Familial melanoma is linked to CDKN2A mutations and confers high lifetime risk.
How Genetic Is Melanoma?
Genetics plays a meaningful role in Melanoma, with heritability estimated at around 58%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Melanoma: CDKN2A,CDK4,MC1R. 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 Melanoma?
Family history does matter. Having close relatives with Melanoma can increase your personal risk, though it is not deterministic. Maintaining a healthy lifestyle and regular screening remain important regardless of family background.
