Consider this: The American Skin Cancer Society estimates that one in five people will have skin cancer in their lifetime; in the US alone, over 5.4 million cases of non-melanoma skin cancer are treated annually. For anyone who spend some time sweating in the sun, that’s more than a bit unsettling.

The best way to prevent skin cancer is to stay UV-protected and covered up with sunscreen or UPF clothing when you’re outside, but that doesn’t eliminate the possibility of developing cancer. It’s just as important to monitor your skin and note any changes in it.
