Prostate problems

I’m still having a 6 monthly psa check as mine is hovering around the 5.5 mark and was 5:9 last time, I’ve had 2 biopsies and 2 mri’s all came back clear but the last one was in 2016 so wouldn’t mind another mri scan as I’m now 55 yrs old apart from peeing more often everything else is perfect down there but you still never know.
