All kinds of skin cancer — melanoma or not — can be very destructive if left untreated. But if you can identify a potential cancer while it’s still small, the cure rate is high. That’s why your first, best defense against skin cancer is frequent self exams. A few minutes with a mirror could save your life.
 
Sun exposure increases your risk of getting skin cancer, especially if you have fair skin. Even one sunburn during childhood significantly raises your lifetime risk. The good news is that sun exposure is something you can control. Just follow a few simple rules:
Limit your exposure during peak hours, 10 A.M. to 4 P.M. Stay in the shade & plan your outside activities for the cooler morning or evening.
Wear sunscreen, or a wide-brimmed hat and long sleeves, or both. Every day. Even on cloudy days and in the winter.
Protect the kids. Most people get 80% of their lifetime sun exposure before age 18.
