There are recent studies going somewhat in that direction. The gist was more or less as follows: - the chemical compounds in sunscreens often break down into potentially toxic/cancer inducing compounds under UV light. YMMV per sunscreen. - metals can be used as UV blocks, and are absorbed by the skin, with potential health risks attached. - the proportion of melanomas in the population groups NOT using sunscreen was indeed higher than in the population groups using sunscreen. HOWEVER,the groups using sunscreen had a prevalence of aggressive melanoma, while the groups not using sunscreen were predominantly diagnosed with the least-aggressive type of melanoma.
