I just had surgery to remove part of my tongue and all the lymph nodes from the right side of my neck about 2 weeks ago. I go to talk with the radiation oncologist on Monday. From what I hear about the side effects of the radiation treatments, I really don't want to do this. Does anyone here have any advice on how to prevent the tooth decay? I think I might be able to manage the dry mouth issues. And are the mouth sores really bad? I'm more scared about the radiation that I was about the surgery.
