It's a hard decision. Radiation is no longer a one time option if you are near any place with a CyberKnife as you can even reradiate tissue that had received IMRT radiation.
I guess the key is "do you feel lucky?" A recurrence is brutal and in my opinion, much much worse than any possible radiation effect. I agree that a second opinion from a CCC would be your best bet if your RO won't make a recommendation.
