I had two, froze today and they were what they call pre-cancerous. BUT….I have a white hide and for years when younger would work in the sun as well as play in t and never even heard of sunscreen. I quit smoking 20 years ago and am suffering from COPD now, bad enough that I can’t do half of what I’d like to. Too little, too late. The doc said today that if I stay vigilant and get in right away when these small patches show up on my hands, arms, face or back and get them froze while still not having formed any cancer I’ll be fine. He also told me that I, like millions of others, will pay for the suntans now until the end. Once this stuff gets started, there is no end to it.
