Personal and Family History
Melanoma Risk Factors Family History
About 5% to 10% of people with melanomas have a STRONG family history of melanoma, meaning two first-degree relatives or three total family members affected with melanoma. Having multiple first-degree family members (parent, sibling, or children) with melanoma increases your risk of developing melanoma 30 to 70 times. (1)
- If you’ve had a past history of melanoma, you are at an increased risk for developing a second primary tumor some time after the original one.
- If you’ve had a past history of melanoma and, in addition, atypical nevi, or a family history of melanoma, your risk is even higher.
At least 5% of all people who have had one melanoma will develop a new independent melanoma.
Frequent skin examinations are strongly recommended if you’ve had a previous melanoma.
