Re: Meaning of PSA Changes
That's a very slow doubling time (close to 4 years) and is fully consistent with age-related increases and possibly prostate size-related increases too. Prostatitis can come and go. Few doctors recommend a biopsy if PSA is under 2.5 and many would wait to 4.0 unless there is some other risk factor, like a positive DRE or a PC death of a first degree relative. I think it's great that you're tracking PSA so you will know if anything unusual occurs.
