Bruce - I really feel for you. Wish myself or anyone had the right answer for you. Unfortunately, there isn't magic answer. No one can tell you if it will rerturn or not without the rads. It's maddening!! My situation was different bec they never found the tumor the first time, ony found the node involvment, had a neck dissection and I didn't have rads. Tumor reared its ugly head the second time with no node involvement, I had TORS (trans oral robotic surgery) to remove the tumor and decided to do radiation only (chemo was not recommended) I have to say the small % difference and the fact that my RO said that either way I went would be a reasonable decision, almost put me over the edge. But he highly recommended radiation and I trusted his opinion, so went with it. I do not regret my decision with both experiences. Do I have dry mouth?yup..do I hate it?...yup..does it get in the way of my job?...yup. However, I made my decision and refuse to look back. I think the biggest thing is not to look back after you have made your decision. I can so relate to the agony of the decision. Praying for the best for you.
