Hang in there, but follow up on the diagnotic steps your doctor suggests. Prostate cancer is very rare for guys your age (OUR age--- I just turned 46). It's usually something else...BUT.... Don't be afraid to push for answers. If you get real concerned, get a bioposy done. That's just my personal slant, but I'd rather have an "unneccessary" biop than not get one and miss something important. Its not as bad a procedure as it sounds (get good drugs from your doc ahead of time!)
Like I said, its MUCH, MUCH, MUCH more likely something else weird going on with you than it is PC...so try not to make yourself nuts. But it does happen. about 4% of prostate cancer cases are under age 50. I had no symptoms but caught it on a PSA....it was relatively far along, but I'm OK now...GOOD LUCK AND KEEP POSTING....the odds are on your side, but follow thru!
