I grew up in Phoenix and southern California. At age 40, got squamous cell on my lip. Dr. said, "What's a 40 year old doing with this on their lip? I see this on 70-80 year old ranchers." Big operation completely through my lip, and then 20 years later came back, so had to do chemotherapy. Be careful with the sun- love it, but too much can be dangerous.Grew up before sunscreen was a thing. Never used it or wore sunglasses. No problemos so far. Very grateful.
