Last year alone, more than 600,000 cases of skin cancer were reported.
Sunlight is the most common cause of melanoma skin cancer.
Any form of tanning, whether it's from the sun, a sunlamp or tanning bed, can significantly increase the risk of skin cancer. Skin cancer often shows up as an irregularly shaped or multi-colored mole. Prevent skin cancer by limiting your time in the sun and by never using a sunlamp or tanning bed. Limit exposure, especially from 10 a.m.-3 p.m. Wear tightly-woven clothing to block the sun's rays.
