I agree with Karen. I started seeing a swallowing therapist at the beginning of my radiation treatment, before swallowing became a problem. She was associated with the ENT doctor and worked out of his office. The first tests were to have a baseline for the coming difficulties. Also I was given some tips to help.

Luckily, I was able to take in liquids all through treatment. But it was hard to swallow solid food for many months. Every food seemed to be an experiment to see if I could swallow it. Finally 8 month after treatment, I was taking in enough food that the feeding tube could come out.
