My tumor was first suspected from a PSA (Prostate Specific Antigen) blood test as part of a physical when I turned 50. I underwent 3 biopsies before the cancer was detected. Each biopsy consisted of 10 samples of the prostate (this procedure really ruins your day). In two samples of the 3rd biopsy(now 12 months had passed and PSA keep rising) a malignancy was detected. If you have trouble urinating, if your stream is poor and you frequently have to get up at night to pee you most likely have some form of prostatitis that could indicate cancer.
If you ever pass blood in your urine don't mess around go to the Doctor. Get your tests every year once your past 50. If detected early you will live-if goes out of the prostate your chance of it killing you goes up logarithmically and it is a bad death.
I understand that as of the last few months there is a new procedure that is not as nearly invasive. There is not a 6 inch belly incision and recovery is a matter of weeks not months.
Don't mess around with this Malady.
