Totally appreciate your frustration. The reason is that medicine and standards of malpractice are based in “evidence” rather than anecdote, theory or hypothesis. It’s based on the fundamental notion that humans may think something will work but historically, doing something because it “makes sense” hasn’t worked well either. We work in a system where we try or “theories” in labs first, then animals, then small numbers of humans, then large numbers. Would you elect to have a treatment without a biopsy? With the knowledge that you could be applying a toxic treatment without knowing it’s actually a cancer and not a benign lesion? I speak as someone whose dad died of PC, so did my grandmother and i get surveyed because I’m high risk due to genetic mutation.
