Q: I love the beach and spend a lot of time in the sun. What's the best way to protect against skin cancer?
Many people wear sunscreen to protect their skin, but several studies have shown increased rates of skin cancer in people who use sunscreen. The exact reason for this association is not known, but it's possible that people who use a lot of sunscreen are simply spending more time in the sun overall, with some of that exposure going unprotected. That's why the very best way to protect against skin cancer is to cover your skin with UV resistant clothing, like shirts, pants, hats, etc. Use barrier protection in addition to sunscreen.
