Almost every time I've had a serious illness the GP has initially diagnosed me with something less severe (flu instead of meningitis, piles instead of colitis, IBS instead of a hernia). With PCa it was only an unrelated blood test that picked it up. Perhaps I'm being unfair, but I get the impression that GPs feel that the public are a feckless bunch of skivers who only go to them to get sicknotes (or worse) and therefore always assume the patient is overstating things.
