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)

Personal History  

• 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. 

Risk

At least 5% of all people who have had one melanoma will develop a new independent melanoma. 

Follow-up Care

Frequent skin examinations are strongly recommended if you've had a previous melanoma.
