Quite so. My entire point is an anecdote relating one doctor's observations re. proportion of late presentations and their availability for study, and attaches that to a comment on US socioeconomic incentives.

Trolling in this thread has attempted twisting that to be a statement about outcomes of treatment, including offering up a paper that, as you note, has essentially nothing to say about the histogram of stage-at-diagnosis. One of these even told me (the OP) to "read the OP", then misquoted my own words to me.

I decline to be gaslit by their intentional misrepresentations, straw man restatements, badgering and sealioning; sadly, of course, that just makes the trolls angrier.
