Your tongue should fit normally at some point in nov 4 I will be 6 months out of rads - as time has passed my tongue has shrunk considerably. My SO saw it last week and said he could debulk it at some point - I saw my plastics guy and told him this and he said nope. - wait. radiation is a natural debulker! (I felt the same way I figure I'll wait a year or so. And then see) however because the new side was so swollen It was jamming my old side up against two misaligned teeth I have in the back causing welts and pain. I told my dental oncologist this and told him I wanted the teeth filed down.. He did it... Even though he kinda scoffed at the irritation theory - but let me tell you the welts are gone and so is the pain... And cell change can be brought on by chronic irritation... Just look at lung cancer... I know you didn't have a reconstruct so you should heal faster.. Good luck!!
