I agree with JohnT's post and recommendation for HGPIN. Ignorant me had HGPIN in a second biopsy in 2000 and went my merry way until a bio in 2008 indicated Gleason Score 10. My new Urologist in 2004 said he would have me have a bio if I had not had one in 2000 that was negative. I did not know enough at the time to insist on a bio because of the HGPIN.
Keep a careful watch with PSA and DRE and be proactive not reactive later.
