Thanks for your question on Chat Doctor. Tongue cancer are usually having good prognosis.  And five year survival rate is 70-80%. Since your wife has already completed 5 years after treatment and at present having large protruding tongue, I advise you to consult oncologist again and discuss palliative surgery (debunking surgery) and palliative chemotherapy. At this moment I think life expectancy in her case is less than 2 years.
