A new trial-emulation study suggests vitamin D supplementation may reduce all-cause mortality by about 25% in people with vitamin D deficiency.






Searching for biologic causes for this epidemic is certainly going to be fruitless at best for most cancers, and at worst find some spurious association that needlessly scares the public.



@AnilMakam I really respect your thoughts and certainly agree some cancers are over-diagnosed. This paper & the response to it are a bit puzzling. They aggregate 8 cancers, chosen by relative⬆️incidence, rather than absolute. This ends up combining/comparing entities w/ diff explanations.








@NiuSanford @UGrewalMD EQUALLY harmful is the narrative that there is an epidemic of early onset cancer. It distorts the entire picture. We deal with these cancers as a group and individually in the paper. Again, did you read it?






Why Some Drs like @AdeAdamson & @vrpatel97 Say There Are Cancers That Shouldn’t Be Treated: Statistics show a clear spike in eight cancers in younger people, but that has brought a debate over whether many cases ever needed to be found. nytimes.com/2025/12/08/hea… via @ginakolata


@UGrewalMD @NiuSanford @vrpatel97 Papers like ours actually give a more full picture by focusing on both incidence AND mortality. It’s unfortunate that you don’t seem to think understanding trends in cancer mortality is important.
