Well, my ENT opted not to do a biopsy. He said that he could not visually see anything that might be a problem. he did look at my previous PET/CT and did say that there was some uptake there, and it is worth checking into to make sure th uptake was decreasing. He also said that since I have noticed swelling in my left jaw/cheek area, not pain at this point that we did to find out what is going on. Once again we play the waiting game. My insurance has to approve it and once they do we will get it ASAP.
