Thanks for the replies.
She has never seen an oncologist - her ENT has said he would refer when we asked, but that it wasn't necessary. She went to her General Pract. and he tried treating it as a canker sore - she then went to her dentist, who did a small biopsy that came back cancerous so he refered her to an oral surgeon in Amarillo, TX (closest "big" town) who did another larger biopsy, who refered her on to the ENT who did her partial glossectomy and lymph node removal - which came back w/ a clear margin and negative lymph. She has since followed up w/ monthly check-ups for 2 1/2 years, which brings us to today.
Do we need to have a referal to get to a Comprehensive C.C.? Thanks again for the information.
