My husband is 8 mos post-Radiation and 3 1/2 months post RND. The dr's said they'll follow up with us monthly for a year but all they do when we go in is look in his nose/mouth/throat, feel his neck and the inside of his mouth, scope his throat and tell us it all looks clear. I'm very suspicious how scientific this is? Wondering if we should have/expect a cat or Pet scan within a few months after surgery? The knot that started all this he had for along time and they never would commit that it was cancerous until they took it out at surgery then said it was all cancerous...wonder how much they can tell by just 'taking a look around' the areas?
