Usually these are not the best physicians - though they likely think they are. There is absolutely not enough time in life to be a great physician and also be a self-promoting megalomaniac. Most of the megalomaniacs essentially suck - which is why you see so many pinhead clinicians in academics.
I was facing ovarian cancer. Everyone thought I had it. There was one test that had me convinced (inhibin) but I still tried to get a differential diagnosis.
The first oncologist surgeon who my Doctor highly recommended refused me a referral to Endocrinology despite me having a CT scan that showed adrenal masses at the 1 cm mark. He said, “I am not worried about those”. I immediately fired him as soon as he said it. He totally disregarded something he should not have but also he totally disregarded the patient who was concerned about the adrenal masses.
In that office visit a bizarre thing happened. I suddenly knew I did not have ovarian cancer. It washed over me like a bright light. But I ran out of time to get the differential diagnosis in case I really did have ovarian cancer.
It turns out, the adrenal masses were causing all the weird labs (except inhibin).
I will never forget the way he totally dismissed me, my CT scans, my concerns, and he ended up being totally wrong.
I try to view the whole experience as a learning curve into the God Complex.
And perhaps the radical hysterectomy saved me from eventually getting cancer that another relative died from.
