Tempted to use that "always has been" meme template here. As an ex-doctor, I can tell you that I very quickly realised that at the top of my "surgical sieve" (a mnemonic that helps docs consider categories of differential diagnoses) one should always start with the category "Iatrogenic" before considering other, more textbook-medicine differentials. And also that for some reason, most doctors seem to treat this category as last on the list, if they think of it at all.
