It seems that there is even some level of doubt that we even _know_ that sun exposure causes melanoma, and what that means, I think we can assume very few people are following a zero tolerance policy of unprotected sun exposure. Reading through a few abstracts, it seems like the connection between sun exposure and melanoma isn’t even all that clear. They make connections between childhood sunburns and melanoma in old age. I kinda get the methodology but it feels too tenuous to make a zero tolerance recommendation, and this seems reflected in the commentary or the papers.
