Gino, I personally would not take the chance. If it is in your lymph nodes, cancer can set up shop anywhere in your body, although I believe lungs, liver, and brain are the most frequent sites. I had rad and chemo. I did not have a terrible time for more than a couple of those weeks. I can spit. I believe radiation saved my life. My non-medical recommendation is to hit this terrible disease with everything available so you can improve the odds of only having to deal with it once.
That said, we will support you in whatever decision you make.
