A toast (of red wine) to your "undetectable" PSA result after two years!
And congratulations on the girls' graduations! AND on longevity of coaching (I've coached 15 seasons combined basketball [10] and soccer, but I'm done.)
Curious, your doctor said you "...only had about 30% chance of walking away when this adventure started"? I'm baffled about this. I don't see anything in your pre-ops stats which would come close to indicating this. Even you post-op results; while your Gleason was aggressive, you had no surgical margins and absolutely nothing posted here to indicate anything but "organ-confined disease" (OCD).
Oh well. Another toast!
