katira,
Your fiancee's situation is similar to mine. Mine was stage III with a single left side lymph node involved. Primary site at base of tongue (left lingual tonsil) Identical treatment. I am still after 2 1/2 moths 100% on the feeding tube. I feel like I can swallow but nothing goes down. I am doing some exercises but no improvment to date. Is your fiancee able to swallow yet.
Mr Mike
