It was not true of all cancers two decades ago. Which is largely my point. Things are better than they were 50 years ago. Including this. Should we try and make sure we don't reverse that progress? Absolutely.

And it is notable that this research largely pointed to genetics as being ~20% of the cases of early onset results. That combined with how it presents in a very different way from older patients seems to point to us also getting better at spotting it.

All of which is good! It is progress. And I hope we get even better at it.

If you are merely noting it as a concern for "things to continue to watch," I'm fully with you. Read the rest of the comments on this post, though. Tons of people pointing at things that just don't present in the evidence. Fear that we will find that one killer ingredient/process to explain the uptick here; all while failing to acknowledge that we did find many such problems in the past and have made quite astounding progress on it.
