Plenty of cloudy days in your region do not mean you are safe from skin cancer, the Washington State Department of Health said in a press release, after it was revealed that the Puget Sound, if it were a state by itself, would rank fourth in the nation for melanoma.
In fact, sun protection — to ward off skin cancer, as well as wrinkles and other signs of premature aging — should be used on cloudy days and sunny days, in both the winter and the summer, experts agree.
There’s good reason to employ SPF: Skin cancer is the most common form of cancer in the world and diagnoses are on the rise. Every year, nearly 10,000 Americans die from melanoma, the deadliest form of the condition, according to the Skin Cancer Foundation. (Source)
