Growing up looking like Casper the Friendly Ghost, I required sunscreen, and many times did not use it and went home from fishing looking like Rudolph. So as I grew up and grew somewhat smarter I started using the best sunscreens I could buy that would not come off while surfing, fishing, or anything else I did out in the sun. One problem, there were places that I didn't think to apply it, and I got cancer.
A couple of years ago I had 2 cancerous cysts removed from behind my left ear. Initially I thought it was from not cleaning behind my ears well enough, but after 2 weeks of using Alcohol and washing them really well and the sores not going away, I went to the doctor. A couple days later I want in for surgery. As you can imagine there isn't much skin behind the ears, so the sores went in deep. As you can see from the pictures they had to cut thru my left ear to get part of it out. I'm telling you now throw pride right out the window, and use hats that cover, sunscreen in all places that the sun may hit, and wash your hands after so it doesn't effect the bait you are using to fish with.
Cancer sucks, do what you can to prevent this type of it.
Not that anyone cares about what I say, but at least try and protect yourselves.
