Needles you say? I used to work in a Urologist's office and I used to give the patients who had prostate cancer their Zoladex injections. It was a pill that was about the size of a benedryl capsule that I would inject subcutaneously, (just beneath the layers of skin) in the belly. The needle was huge and I would have to use lido /c epi to numb it first. those poor guys must've hated me! and the tx wasn't cheap! like $350 a month on top of what else they had to take.
I once had a woman come in to see the doctor, when I asked her what was the reason for her visit, she said "I think I have prostate cancer"! It was all I could do to get out of the room without busting a gut! I did stumble on the way out, so she probably thought that was the reason we all were laughing our butts off. Needless to say she just had a UTI. (bladder infection)
