Aged 55 now, story started like many with a slightly high PSA of 3.9 for my age.
Had mpMRI which was normal and subsequent PSA was 4.1 and had TP biopsy which also came back as normal.
6 months later and PSA check was 7.1 so consultant says he won't release me until that PSA drops a bit but having 'passed' those 2 tests, highly unlikely anything sinister, but not impossible biopsy missed something at the back of the prostate.
Feel extremely relaxed quite honestly and lucky I guess the consultant is so thorough. As he said, even with the slim chance of something being missed, the PSA would be many times higher if something very bad was establishing itself.
