I just recovered from a heavy duty surgery, 6 hrs 6 Dr's from a very painful sore on the top of my mouth. It has been very hard for me, this time, and is my 4th cancer. First one, radiation, and surgery on the others. If you still smoke, quit. And if you don't get a good answer, go to another head and neck surgeon. I have been misdiagnosed twice, and I knew I had cancer, so I just went to another Dr. I don't mess around anymore. I wish you the best.
