Lambana:
I can sense the fear/wishful thinking in your post.
I would suggest NOT doing the PSA every 30 days for 90 days as you indicate.
I would suggest 2-3 weeks on an antibiotic and retest.
What was your Free PSA result?
Also, assuming the PSA does not decline markedly after the antibiotics, you are a perfect candidate for the PCA-3 test.
That is an easy test (pee into a cup after a DRE) and it is very specific for PC. I was in your situation and that test was very definitive for me, leading to a biopsy. Hopefully for you it will be a good result.
I hate reading that the doctor took all of 30 seconds. Sadly, that is too often the case.
