After my first radiation, I was told no more was possible. Even after the recurrence, the Radiologist was firm that only surgery was an option now. Even after the surgery, the RO said no radiation. When the pathology report came back and indicated that the cancer would indeed come back a third time, suddenly the RO decided to give my another 25GY in a concentrated one hour session on Cyberknife for 5 days in a row.
I was warned I may never swallow again as a result, but like yourself felt I had to do whatever it took. Oh, and they threw in more chemo also.
Sofar it is working out for me as I am alive.
So yes, I think you did the right thing
