Skin Cancer Risk Factors

Skin color and being exposed to sunlight can increase the risk of nonmelanoma skin cancer and actinic keratosis.

Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for basal cell carcinoma and squamous cell carcinoma include the following:

  • Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time.
  • Having a fair complexion, which includes the following:
    • Fair skin that freckles and burns easily, does not tan, or tans poorly.
    • Blue or green or other light-colored eyes.
    • Red or blond hair.
  • Having actinic keratosis.
  • Past treatment with radiation.
  • Having a weakened immune system.
  • Having certain changes in the genes that are linked to skin cancer.
  • Being exposed to arsenic.
