Its over six years since I had cancer in lower left jaw removed, and recent check up has located a swelling in lower right jaw. Surgeon gut feel is good, but he will not take a chance and has decided to operate and remove whatever it is, then biopsy it.
Certainly didn't expect to be having neck surgery again !!! But that appears to be a hazard of the big C.
