The Causes of Skin Cancer

Sunlight is the underlying cause for most skin cancers:

  • Chronic sun exposure is linked to nonmelanomas
  • Intermittent, intense exposure is linked to melanoma

For example, people who are in the sun:

  • Regularly are at greater risk for developing nonmelanoma skin cancer
  • Occasionally but get sunburned have a higher risk of developing melanoma

What About Tanning Beds?

Studies show there’s a link between developing melanoma and using a tanning bed on a regular basis. There’s been an increase in the number of young women developing melanoma, particularly on their trunk, who have a history of using tanning beds.

What About Genetics?

Some cases of skin cancer are inherited or have a genetic basis. If skin cancer is inherited, it’s usually seen in families with a number of members diagnosed with skin cancer.

If you have a first-degree relative (parent, sibling, child) with skin cancer, your risk is greater than the regular population for developing skin cancer. If you have a history of skin cancer, you have an increased risk of developing skin cancer again.

If you are concerned that you or a member of your family may have a hereditary condition that may affect your chances of developing melanoma, a more dangerous form of skin cancer, ask your physician for a referral to the Scott & White Cancer Genetics Clinic for genetic counseling and possible genetic testing to determine whether you have a genetic predisposition to the disease.
