Skin cancer is the abnormal growth of skin cells. It appears as changes to the color, shape, or size of a mole, lesion, or skin spot. These changes can be triggered by a variety of factors, including too much sunlight exposure.
Skin cancer is the most common form of cancer in the United States. More new cases are diagnosed each year than breast, prostate, lung, and colon cancers combined. Around one in five Americans will develop skin cancer in their lifetime.

These are the common risk factors for skin cancer:
Most of our patients are between age 40 and 70. However, a growing number of younger patients are beginning to develop melanoma, the deadliest type of skin cancer. Data from the Skin Cancer Foundation estimate the rate of melanoma in 18- to 39-year-olds increased 800 percent in young women and 400 percent in young men between 1970 and 2009. This is likely due to poor sun safety practices and tanning bed use.
Though fair-skinned people are at higher risk, dark-skinned people can and do develop skin cancer. Minorities – including African Americans, Hispanics, and Asian Indians – often are diagnosed at a more advanced stage of skin cancer and tend to have worse outcomes than Caucasians.
That means skin cancer is a health concern regardless of your skin color. But skin cancer is also highly curable with early detection and treatment.
Michigan residents need to be cautious about two specific risk factors -- low vitamin D levels and increased tanning bed use.
Humans need vitamin D, and one source is from sunlight. Vitamin D is made in the skin after exposure to UVB rays -- the same light that causes sunburn, tanning, and other skin damage. Many people tell us they have low vitamin D levels, so they skip sunscreen to raise their levels. But that’s not how it works.
Though you need some UVB exposure, it’s important to practice sun safety. Talk to your doctor about taking a supplement if you’re concerned about your vitamin D level.
Indoor tanning greatly increases the risk of melanoma. We see more people in their 20s with melanoma because of increased tanning bed use. Tanning is the skin’s reaction to damage from sunlight or UVB rays. It’s not a way to protect yourself from sunburn or skin cancer, as some patients mistakenly believe.
Everyone should practice sun safety. Use these guidelines to reduce your risk:
