On the other hand: intentionally misrepresenting people's statements, and crudely and inappropriately manipulating statistics, sets off my bullshit detector.
A stage IV of any single one of the myriad subtypes of cancer is not a representative example of all cancers, let alone a guide to their stage distribution. Cherry-picking one, and then grossly distorting its stats, tells us nothing.
The simple fact is, a very senior doctor, whose job is to diagnose cancer, observed that US institutions have a disproportionately large collection of late-stage presentations to study.
So since you’re the OP, do you want to share the tumor type that “you rarely see stage 4 in Australia” but is apparently super common at Stanford? Since I work in healthcare I’d be super interested to know.
Had it not come on the coat-tails of such bad-faith misquoting, cherry-picking, statistical manipulation, misrepresentation et cetera, perhaps I might. Instead I bid you a good day.
And no, a general observation of "we don't see stage 4 cancers in Australia, we have to go to the US" is clearly invalidated by this data. There are plenty of stage 4 cancers in Australia.
Take a look at the US Seer data it appears more is diagnosed earlier in the US.[1] 50% are not stage IV and only 2% are unstaged.
