Mark,
My RO rcommended a full body CT/PET scan every 3 months for the 1st year with monthy visits to an ENT. From what I've read before you should have a PET scan yearly. But hey what do I know I'm uglier or was it tougher than the undertaker.
Update on me:
Tomorrow is 3 weeks post rad treatment for me. And today I ate a full breakfast at IHOP...pancakes, eggs, bacon, country gravy smothered hash browns. I couldn't taste it all but I thought I could taste a little initially.
