Hi Uncle H and Welcome:
Since you are considering watchful waiting, here is a link to the well known Johns Hopkins program which may provide you with some helpful info.

Also, I recommend that you discuss your case with EXPERIENCED practioners...prostate oncologist, radiation oncologist and surgeon (robotic and open). By experience I mean at least 300 procedures...
Good luck and let us know how you make out.
