I'd like to add that IMHO, any radiation oncologist that fails to test a head and neck patient to get a baseline TSH before starting treatments is guilty of malpractice.

Mark, 21 Year survivor, SCC right tonsil, 3 nodes positive, one with extra-capsular spread. I never asked what stage (would have scared me anyway) Right side tonsillectomy, radical neck dissection right side, maximum radiation to both sides, no chemo, no PEG, age 40 when diagnosed.
