Bottom line: It seems much harder to get a fix on the competence of an RO and staff. It really is.
I met with the RO twice and eventually I just went with my gut feeling and also tempered by the fact that my local facility is THE MAJOR facility in mid-Michigan and they do use the Varian Trilogy RapidArc. Still, who knows...
I was much more confident on the surgery side as I was getting done by, for sure, one of the top people in the country.
If SRT fails, I will most assuredly be seeking out a top medical oncologist specializing only in PC. As of now, my thinking is Dr. Hussein at Umich and probably also a consult with Dr. Scholz in LA
