I also say go for a 2nd and 3rd opinion. Although lucky, I have had 8 recurrences that were treatable, so far. I'm on my 5th different radiation treatment, and there are ways to do more radiation in some, and had 192Gy, really more with IORT, so far, while most say they had the max at 70Gy, and can't have any more. Not all doctors or hospitals may have experience to do this or want to risk it, but I have some of the best. For recurrences, surgery is usually the best option, followed by maybe radiation, chemo radiation, but each case is unique. NYC has the most top doctors, and hospitals in the country, and know a half dozen that are top in ENT, and treat recurrences often. If possible, you can stay at Hope Lodge on 32nd for free, which I can't say enough about, and consult with the various hospitals in Manhattan...Beth Israel, Mt. Sinai, MSKCC, NYU, NY Presbyterian, Lenox Hill to name a few.

Best of luck.
