I didn’t realize this was controversial. This is only n=1 evidence (and not necessarily cancerous), but a cleanly controlled natural experiment that visually demonstrates non-sunburn skin damage via consistent asymmetric sun exposure on one side of a truck driver’s face: https://www.nejm.org/doi/full/10.1056/NEJMicm1104059
For something more scientific, maybe these work better?
It’s not controversial. I don’t think anyone knowledgeable in oncology would dispute that sub-sunburn UV exposure significantly increases risk of skin cancer. My aim here was to explain why we can be confident of this belief in as straightforward of a way as I can.
I haven’t looked at your links in detail, but the first and second cover the same ground as the first and second points I made (observable DNA damage + cancer from indoor tanning). As for the third, I wanted to avoid resting any points solely on cohort studies because I didn’t want to get into too much of the controversy there. Though I ended up getting pulled into iton Reddit anyways.
