Take a breath. It sounds like you have got things covered. My dad had two bouts of oral cancer in his upper palate. He has a prosthetic and he is 95, his last surgery was 10 years ago. He never had radiation although it was recommended after the first surgery. Having OC is not automatically a death sentence. There are lots of check ins of long term survivors on this forum, check them out. That said, I know how you feel. I was diagnosed almost a year ago with SCC on the right side tongue. I had surgery in Feb and started 30 rounds of radiation in March. I just had my first post treatment PET scan and am seeing my doctor this week, hoping all is good as the doctors assure me it will be. You are in the right place for support and encouragement along your journey, we've all been there. The treatment for your cancer is going to be rough, no way around it, OC treatment is tough.
