Does family history really increase melanoma risk?
Yes, family history significantly increases melanoma risk.
If a close relative had melanoma:
• Your lifetime risk is higher
• Surveillance should begin earlier
• Exams should be more frequent
A family history of melanoma significantly increases a person’s risk of developing the disease because it often reflects a combination of genetic and environmental factors. Individuals with a first-degree relative who has had melanoma have about a two- to three-fold higher risk than the general population. This increased risk is often linked to inherited mutations in genes such as CDKN2A, CDK4, BAP1, or MITF, which affect cell cycle regulation and make it easier for skin cells to become cancerous. These mutations can lead to a higher number of atypical moles, earlier onset of melanoma, and multiple affected family members. Shared environmental factors, such as sun exposure habits, fair skin, freckling, and the tendency to burn easily, can further compound the risk. Because of this, people with a strong family history of melanoma are encouraged to have regular dermatologic exams, perform self-skin checks, and consider genetic counseling or testing if multiple relatives are affected.
Even without family history, melanoma can still occur. Know your family history and share it with your dermatologist.
