On call: Prostatic intraepithelial neoplasia
Q. My prostate is not enlarged and I have no urinary tract symptoms, but I've had three prostate biopsies over the past four years because my PSA has gone from 3.2 to 4.8. The first two biopsies were normal, but the new one found "PIN" but no cancer.
Please explain "PIN" and tell me what it means for me. I'm 59 years old, and except for my prostate, I don't have a worry in the world.
