I had a PET/CT scan prior to treatment, then one about 3 months after treatment, and again at 5 months, due to what turned out to be false positives.

I have ongoing appointments with my MO, RO and the Surgical Oncoloogist/ENT. The first year I was seen every 90 days by each doctor, staggered so that I saw somebody every month. This year, they have extended a bit to every four months, which staggers out to about 6 weeks between appointments. The surgical oncologist/ENT, and the RO do extensive examinations of the head and neck. The MO does a more cursory examination, but I have a blood draw every visit with him, and a Chest X Ray every other visit. He also does a more thorough examination of lungs, abdomen, etc.

All in all, I feel I am pretty well prodded, poked and otherwise assessed on a regular basis. ;-)
