A major risk factor is exposure to ultraviolet (UV) radiation. People who spend a lot of time in the sun--the major source of UV rays--or use tanning beds increase their risk of developing skin cancer. Family history plays a role, as does race: Caucasians, especially those with fair skin and light-colored hair, have a melanoma risk 10 times higher that of African Americans, and a higher risk overall for any type of skin cancer. Age and gender are factors: before age 40, women are at higher risk; after age 40, the risk is higher in men. An abundance of moles also increases risk; people who have many moles should have regular, thorough skin exams by a dermatologist, according to the American Cancer Association. Smokers have a higher incidence of developing squamous cell skin cancer, especially on the lips.
