I remember very well several times when I "felt" something or looked into a mirror and saw something it would affect my attitude and demeanor for days. Usually I would let it bug me until I couldn't stand it any more then I'd call the ENT and he would look and say that is "normal" and everything looks fine.

If this "spot" is of concern to Jerry's ENT then have her deal with it (as in biopsy) I wonder if her concern is not about cancer but instead about the non healing spot being a different kind of problem related to the radiation (but due to her bad "bedside manners" is unable to spell that out for you). If it is just not healing then she should be giving you options for how to fix that. Hyperbaric oxygen treatment (which is painless) comes to mind. Jerry's sore throat may just be infection from this non healing spot. My suggestion is to get more answers from this ENT of find another ENT. Having to deal with an arrogant Doc. while going through this would have made me crazy.
