I have located a Cancer Care Center, not sure if it comprehensive, but did locate an oncologist who has done research in the area of head and neck cancer. I will discussing this with my ENT next Wed, at my appt. I will probably go ahead and get in with a consultation and see what he thinks. At this point I still do not know what to think. Hubby said that they got it all, but I will not be convinced until I see proof. I just do not trust what people say anymore. Afterall every Dr, I went to told me it was just an ulcer and it would get better and it never did. Kept getting worse.
