The whole point of AS is to actively monitor things--with regular PSA blood draws, MRI's, follow up biopsies, etc--and IF something pops, THEN you make an aggressive treatment decision. AS is not "sitting tight", not exactly.
I think, in your case, this is a great plan. You're low risk...and the other tests confirm it. The two doctors disagreeing about
what to call what they found on the DRE is just that...a disagreement. It's ok, and it's a minor thing. The other scans you've had are much more important.
The best thing about
AS is that there are now long term studies out that show AS, done properly (and it sounds like you're in a 'done right' program), poses NO increased risk for long term survival. The roughly 50% of patients on AS who eventually do treat, have no statistically different outcomes from those who treat immediately--they just put off the potential side effects for a while.
