husband has 4 more radiation treatments. What happens once he is done? PET scans, doctor appts, etc? How long until cancer is gone if treatment was successful? just curious what this all looks like.

BTW...except for sleeping a lot and spitting out saliva, no one would probably know he is going through treatment. He doesn't complain of a sore throat and once that feeding tube got replaced, he seems pretty normal. He's not one to hide feeling badly so I have to assume he doesn't feel too badly. He just started using pain medication last week (week 6). He has a voice some days and other days no voice. He can still drive himself any time he feels like it and does. So much for doctor saying it's like a 100 times a sunburn in his throat and it's the worse thing they could do to a human....it's been nothing like that. It was so much worse with the feeding tube and the first chemo treatment. The rest has not been so bad. (he might beg to differ! just my observations.)
