Hi Tabitha, it would appear that your boyfriend has had a very similar operation to me, so at 5 weeks into his radiotherapy, i would imagine that his mouth is feeling quite sore. My tongue is still a bit swollen but do reassure your boyfriend that his tongue will return to normal, but it does vary in time scale from person to person. I finished my treatment about 10 weeks ago and for the last couple of days i have moved on to soft food and no longer have to puree everything. Please tell your boyfriend to hang in there as it does get better, and his tongue will go down. Speedy recovery, Clive.
