don't know if there's formal studies, but it oughta be pretty easy to compare rates of skin cancer between different jobs in the trades. if the sun is causing skin cancer, then roofers and concrete/cement guys should be at higher risk than, say, drywallers and flooring guys.

Good idea. It would control for a lot of confounding variables elegantly.
