Good question — should I be concerned. My PSA jumped from 2.1 to 4.2 in one year. My doctor told me it was okay and just above the 4.0 level. I didn’t agree with my doctor’s opinion, because it had double in one year. I found another doctor and got retested. It was 4.2 again; however, this doctor was concerned. Long story short, half my prostate had cancer and it had spread out and was found in a lump node. Ugh.
Good luck with your outcome. It’s great you’re making an assessment of your situation.
