I was on AS for 2.75 years, had lots of BPH, did a second biopsy at Mayo. But when I got Tulsa Pro I went outside Mayo to Dr Scionti in FL. One can get some real good discussion with all the doctors including Mayo, but nothing will beat your own reading around, plus calling and meeting all kinds of doctors at many places. I met with all kinds during AS and after my second biopsy said I needed treatment, but finding them all in one place will be hard. Yes do meet with every doctor you can at Mayo, but do meet with many others. If you want you can read more about my Tulsa and my prostate cancer issues here:

I probably had some unique issues in that MRI contrast seemed to do a less good job since I started AS, so that made it hard.
