Hey gem1128, Don’t look back and kick yourself for choices you made. You did the right thing.
If you chose radiation and your cancer extended beyond the capsule, figuring the margins would have been educated guesswork no matter if they used Cyberknife or MRI guided treatment.
If the cancer extended beyond the target area it would have been missed and you’d be right where you are now, but with less options.
If EBRT was used it might have had a better chance, but without ADT, who knows??
Hopefully your radiation team will kill this thing once and for all. And be SURE they plan to radiate the pelvic nodes as well. No matter what the PSMA shows or what your RO ‘thinks’, just be sure they target everything they possibly can. Best,
Phil
