This is something I've been wondering about. Does your risk for getting skin cancer only go up when you are sunburned, or does it also go up when you get a tan (from being outside, not from tanning beds)? I've been worried lately because it's summer, and I've been outside everyday to play tennis. I now only go out after seven, before it starts getting dark, but I'm worried because I haven't been using sunscreen. I haven't gotten sunburned yet, only tanned. But should I be worried? The last thing I want to get is skin cancer and/or premature wrinkles.
