Well, I had similar thoughts to mehwoot's opinions. Doctors generally need to set expectations low. Some might not have the best bedside manner in doing so, but I feel like it's better than overpromising and underdelivering.

source: I am 42, and I had cancer when I was 16 (very similar to Lance Armstrong's prognosis, minus the brain cancer) and again when I was 37.

I agree. I think that this sort of thing is going to produce a "me against the world" mentality, and so I understand why these reactions occur. But although I understand it, I don't think it is right to say "fuck you" to the doctor who treated you, unless there is real cause for it. Their job is already hard enough.

Thank you for relating your story, I can see why anger is common among those facing (possibly) terminal illnesses.
