You're confusing me with u/addisonl. Please check usernames before accusing people of trying to "silence the other side."
To quote a blog post I wrote on why we can be confident sun exposure causes cancer: "Green et al. (2011) conducted a 10-year study (n=1621) in Nambour, a town in Queensland, Australia. Participants were randomly assigned to daily or discretionary sunscreen application. After 10 years, 11 melanomas were found in the daily group and 22 in the discretionary group."
But you should read the full post for more context on why we have much better data than randomized controlled trials, and why correlation studies on this subject are nearly useless due to the impossibility of finding reliable proxy variables: https://hedonicescalator.substack.com/p/contra-byrnes-on-uv-and-cancer https://hedonicescalator.substack.com/p/contra-byrnes-on-uv-...
Saying "some of the ingredients in US sunscreens are themselves associated with cancer" is meaningless without more specificity. As the meme goes, this HackerNews comment is known to the state of California to cause cancer: the bar for something to be "associated with cancer" is incredibly low. Are there any particular chemicals or chemical classes you were worried about?
And I will remind you that, in contrast, we are 100% sure that sunlight causes cancer. We know exactly what kinds of DNA damage it creates (chiefly cyclobutane pyrimidine dimers, which I discuss in my blog post) and we can find cancer-causing mutations in melanoma samples directly downstream of that damage (C->T mutations, for example, ones that disable the key p53 tumor suppressor gene). We know how this shit works! Are there some sunscreen formulas that might be dangerous? Possibly, I don't have them all memorized, but the solution is to find a different brand... not to instead expose yourself to one of the best-studied carcinogens around.
