Dear @mindyt, I have had radiation for Pyriform Sinus Cancer. These two pouches, are located down by the vocal cords. My pen-pal friend has also had radiation for throat cancer. We both suffer in different ways. Your question about surgery to remove scar tissue is a good one. Here is what we have both been told by several different ENT's: Radiated tissue can become necrotic (rot) if any type of surgery is performed. One ENT described radiated tissue as "mush." Unfortunately, it can become necrotic on its own too. My friend has been on a feeding tube for over two years, as she can not eat, drink, and can barely talk. Her Epiglottis is fused to her throat from the radiation. Any tampering could produce disastrous results. We both have tracheotomies, as my Vocal Cords are paralyzed. I could barely breathe, thus, the Tracheotomy. Everyone is different, but when it comes to radiated tissue, it is a sad situation. As the doctors usually say, "at least you are alive." I foresee the day when less destructive methods are utilized to cure cancer, however, it probably will not be in my lifetime, as I am in my 60s. Good luck Mindy, and know you are not alone. Stay close to our maker, and you will find peace.
