Jenn,
My RO Docs were ambivalent about post op radiation. My ENT Doc said I didn't need it, that we were going to be doing checkups every month and would keep tabs on things.
The decision at this fork in the road is the hardest one I have ever made. I ended up reading all the research papers I could find online, hearing the doc's opinions and the rationale behind those opinions, and going with what I thought would do me the most good and the least harm. (I didn't have to use that heads/tails decision making tool after all!!)
Although many on this board will worry with me over my decision not to radiate right now, only Time will tell me if the decision was the right one!

Best wishes for a full recovery,
Andrea
