 How do I prevent skin cancer?

Sun exposure is the most preventable risk factor for all skin cancers, including melanoma.^1,2 You can have fun in the sun and decrease your risk of skin cancer. Here's how you can prevent skin cancer:   

• Seek shade when appropriate. Remember that the sun’s rays are strongest between 10 a.m. and 2 p.m. If your shadow appears to be shorter than you are, seek shade.
• Wear protective clothing, such as a long-sleeved shirt, pants, a wide-brimmed hat, and sunglasses, where possible.
• Generously apply a broad-spectrum, water-resistant sunscreen with a Sun Protection Factor (SPF) of 30 or more to all exposed skin. “Broad-spectrum” provides protection from both ultraviolet A (UVA) and ultraviolet B (UVB) rays. Reapply approximately every two hours, even on cloudy days, and after swimming or sweating.
• Use extra caution near water, snow, and sand because they reflect and intensify the damaging rays of the sun, which can increase your chances of sunburn.
• Avoid tanning beds. Ultraviolet light from the sun and tanning beds can cause skin cancer and wrinkling. If you want to look tan, consider using a self-tanning product or spray, but continue to use sunscreen with it.
