Sorry about your Mom. A quick scope of the throat could have confirmed the yeast infection, I think. I was told my enlarged tonsil was a cryptic tonsil for two years. I suppose because I was young, healthy and fit. There is a bit of ignorance out there on the part of doctors. I feel as though if my ENT had known about the HPV-oral cancer link, he MIGHT have been more alarmed and maybe even asked me if I knew whether or not I had HPV.
