I'm in a similar situation. My PSA this year was 8.1 in Jan and 4.4 in June. Then back up to 7.1 in October. First MRI was a Pirads 3 with a 95ml prostate and my second MRI was a Pirads 2 with a 70ml prostate. My urologist still believes I would benefit from a biopsy but he also said there is nothing to target. So I'm doing another PSA in December and paying attention to prostate density and any upward trends in my PSA. My free PSA was 13.5% but went up to 17.8%.
