Well...word is people at the equator do NOT get skin cancer at rates of those in North America...Seems Vitamin D probably plays a role. Cover up with sunscreen....block Vitamin D.
People cover up far too much with sunscreen. I need sunscreen but I can do one hour in the sun and it’s good for me. Vitamin d. Thereafter I do need sunscreen but I use mineral sunscreens, using zinc oxide usually.
Some of those chemical ones really could mess with hormones and maybe even increase risk of harm from cancer.
