Just as everyone has said above, don't wait, he has to find out what he is dealing with, it may be just nothing, a friend of mine psa jumped to 12, had biopsy and came back negative, put on cipro and now back to normal, mine was 4.7 and had 40% gland involvement, and positive DRE with nodule felt, please inform him to find out.
As far as biopsy, my urologist gives all his patients the twilight anesthesia or what the anethetists call "milk of amnesia", it's the same stuff they give you for a colonoscopy. I don't remember a thing, 1st had an iv then the next thing I remember my wife was coming down the hall to get me.
I hope he finds out.
