Yes. Although sun exposure is responsible for most cases of melanoma, a family history of the disease can also be a risk factor. You are especially at risk if other members of your immediate family have had melanoma. People with atypical moles (nevi) are also at higher risk for developing melanoma. Individuals with a family history of melanoma, or who have had melanoma in the past, may need to see a dermatologist regularly in addition to performing self-examinations. Talk to your dermatologist about how often you should be professionally screened.
