Vitamin D has anti-cancer effects which apply more generally than skin cancer. In studies which assess all-cause mortality relative to UV-B exposure, higher UV-B exposure is correlated with lower all-cause mortality. That is, more skin cancer yes, but also less death because of improved overall health and lower overall cancer risks. Importantly, this is not an endorsement of artificial tanning, which correlates with greater all-cause mortality.
