I started IMRT watching my diet. As time went on I would occasionally eat foods that were not advised and toward the end of the 39 sessions I was eating anything I wanted in moderation. I even had pizza and beer once. No ill effects.
My treatment plan going forward is 16 mos of ADT (zytiga prednisone and eligard). In Sept of 2024 all meds to be withdrawn and PSA test every 3 mos.. IF (when) PSA increases to > 0.4 ng/ml. I expect a PSMA pet/ct scan to show some specific locations of recurrence . Those areas can then be treated by the appropriate therapy and then perhaps ADT again.
"Rinse and repeat" until something else takes me out.
