Welcome to the Oral Cancer Foundation Paul,

Glad to hear you are doing so well after your surgery.

I don't believe there is a surgeon who can positively say he got all the cancer. If you read some of the older posts most recommend radiation and/or Chemo after the surgery. You want to make sure all the cancer cells are gone. Radiation should clean up any tiny cells that may have spread waiting to start up again. Everyone reacts differentely to the same treatment. You may not experience the bad side effects of the radiation. My advise to you is to
attack this cancer with every weapon avaiable to you the first time.

Best Wishes, Dan
