An iced pick-me-up is a great way to start your summer mornings. Better yet: drinking a single cup of coffee daily may lower your risk of developing skin cancer. In one study of more than 93,000 women, published in the European Journal of Cancer Prevention, those who drank one cup of caffeinated coffee a day reduced their risk of developing nonmelanoma skin cancer by about 10 percent. And the more they drank—up to about 6 cups or so per day—the lower their risk. Decaf didn’t seem to offer the same protection.
