I am 60 years old. Ever since I started taking PSA tests (around ten years), they hovered from about 3.8 to 4.8. I have chonic prostatitis, which I understand may causes the fluctuation. My most recent result result was 4.8. My doc put me on a month-long course of antibiotic to see if he could get the PSA number down by solving the prostatitis problem. But after the four week, the PSA reamined about the same (actually rose a bit to 4.85). My doc had said if he couldn't get the PSA below 4 with antibiotics he would want to do a biopsy. I'll be seeing him later this week to discuss it.
My question is this: with a PSA of 4.8, which is not that high for me, should I agree to have a biopsy. In other words, are the pontetial problems with a biopsy worth the benefit given that my PSA is still relatively low?
