This is an unavoidable problem of any observational study. Do we have any randomized controlled trials that support the current dogma of sun = bad?

- derbOac 4y agoThere were some randomized controlled trials in Australia where they instructed people to use sunscreen vs not and then followed them up over 10-15 years or so. They couldn't rigorously control use over the period of the study but found that people differed by condition, and the group instructed to use sunscreen had lower rates of melanoma and markers of skin aging. I would post links but when I search for the studies I get a barrage of summaries without actually linking to the original study. I think this study is part of it: doi:10.1001/archderm.139.4.451 I think this summarizes another part of the study: https://www.cancer.org.au/blog/world-leading-research-confirms-regular-sunscreen-use-can-prevent-melanoma https://www.cancer.org.au/blog/world-leading-research-confir...
