I will say in my unprofessional opinion that I am pro-tube even though I hated the damn thing...
I have no swallowing issues 1 year out. But I do recall that trying to feed orally would have been extremely difficult pain wise given the rawness of my mouth and throat.
Not to mention taste issues which I don't honestly believe is a indicator to get one but everything but filtered water was horrid around the 4th week of radiation until about 1.5 -3 months post treatment.
