Thank you Christine for your advice. I couldn't bare to have someone else drive him, that wasn't my brother or myself. He's so depressed and is crying if he doesn't hear what he wants.
I'm not sure how SS is affected either, but I am getting the letter today from ENT specialist.
My Dad is so frustrated, he sees things moving along slowly. His cancer is eating away at his palate, has more holes. ENT said not operable, but that there is another DR at another CCC that has done major surgeries and used skin graft to reconstruct, since he would lose his jaw & part of his neck. He just recommended not doing that until we got a PET scan to determine it hasn't spread or we would be putting him through a useless surgery. Does anyone know of a survivor of recurrent cancer in the oral cavity? I'm desperate to find him some hope, he is so depressed.
