This is a story we hear far too often. ENT's that are not in the subspecialty of their type of medicine that actually sees cancer patients, often do not get - that in a differential diagnosis, the first thing to eliminate is the one that is most dangerous, cancer. So they go through a litany of things that MOST of their patients have, looking for bacterial infections, viral issues, and more. This too often is a big waste of important time, when the first thing to eliminate from the differential diagnosis is the thing that can kill a patient, cancer. That can be done through a simple fine needle biopsy, and the pathologist will give them a black and white answer as to what it is. All this other stuff that your post mentions, that is delaying getting THE answer that you want eliminated for the potential problems. If it isn't cancer, great now they can spend their time chasing what is cause the non lethal problem that you have and correcting it.

I suggest that if you want this particular doctor to continue this pursuit, that you allow him to, AFTER HE HAS DONE A FINE NEEDLE BIOPSY OF THE IMPACTED AREAS, INCLUDING THE NODES INVOLVED AND THE TONSIL. It is important that you are your own strong advocate for early definitive diagnosis.
