Harley...I am by no means an expert but I would not get radiation before you talk to a doctor at CCC. I was diagnosed with stage 1 SCC and I have had 4 partial glossectomies. I have seen 3 doctors and very good cancer hospitals and none of them think I should have radiation. Who did your partial glossectomy? Was it your ENT?
Please get a second opinion before you do anything. Like Christine said, radiation can only be used one in the same spot.
