Hello @preyn. I am a 64-year-old-woman, diagnosed with Pyriform Sinus cancer in 2018. If you go onto my profile, I have written extensively about my journey. If you have any questions, feel free to ask. It is a slow journey to recover the functions of the throat after treatment, yet is very possible with throat exercises, and the best one of all...time. Please research "Red Light Therapy," as it has proven to help radiated tissue. I utilized a small, inexpensive wand twice-a-day during my radiation treatments, by waving it inside my throat and mouth area. The main thing that helped me greatly was prayer. Best wishes to you and your husband in this journey.
