Yes, you’ll find that while on active surveillance having biopsies every few years is common. Recently, some have started just having MRIs every few years and then only IF there’s been a change, only then having a repeat biopsy. I’m not sure how much that’s caught on.
With a Gleason 6(3+3), I was on active surveillance from 2012-2021; during that time I had 4 transrectal biopsies. All were uneventful and I never got an infection.
With my PSA continuing to rise (to 7.976), that final biopsy showed a Gleason of 7(3+4). It was then that I had treatment (proton radiation).
