Overview

Sunlight exposure is the most important risk factor for the development of dysplastic nevus.

Risk Factors

  • Having more than 50 common moles
  • Sunlight: Sunlight is a source of UV radiation, which causes skin damage that can lead to melanoma and other skin cancers.Severe, blistering sunburns: People who have had at least one severe, blistering sunburn have an increased chance of melanoma. Although people who burn easily are more likely to have had sunburns as a child, sunburns during adulthood also increase the chance of melanoma.
  • Lifetime sun exposure: The greater the total amount of sun exposure over a lifetime, the greater the chance of melanoma.
  • Tanning: Although having skin that tans well lowers the risk of sunburn, even people who tan well without sunburning increase their chance of melanoma by spending time in the sun without protection.
  • Sunlight can be reflected by sand, water, snow, ice, and pavement. The sun's rays can get through clouds, windshields, windows, and light clothing.

In the United States, skin cancer is more common where the sun is strong. For example, a larger proportion of people in Texas than Minnesota get skin cancer. Also, the sun is strong at higher elevations, such as in the mountains.

  • Sunlamps and tanning booths: UV radiation from artificial sources, such as sunlamps and tanning booths, can cause skin damage and melanoma. Health care providers strongly encourage people, especially young people, to avoid using sunlamps and tanning booths. The risk of skin cancer is greatly increased by using sunlamps and tanning booths before age 30.
  • Personal history: People who have had melanoma have an increased risk of developing other melanomas.
  • Family history: Melanoma sometimes runs in families. People who have two or more close relatives (mother, father, sister, brother, or child) with melanoma have an increased chance of melanoma. In rare cases, members of a family will have an inherited disorder, such as xeroderma pigmentosum, that makes the skin extremely sensitive to the sun and greatly increases the chance of melanoma
  • Skin that burns easily: People who have fair (pale) skin that burns easily in the sun, blue or gray eyes, red or blond hair, or many freckles have an increased chance of melanoma.
  • Certain medical conditions or medicines: Medical conditions or medicines (such as some antibiotics, hormones, or antidepressants) that make skin more sensitive to the sun or that suppress the immune system increase the chance of melanoma.
