I was wondering about the latest on HBO, too. I am most likely having a thyroidectomy in the next couple of months. My ENT said he would not undergo the surgery without HBO. When I asked my oncologist, he said they rarely prescribe HBO, and they are not certain it does any good.

Left tonsil SCC, HPV+. T2N0M0. Tonsillectomy 3-07, bilateral radiation, cisplatin 3x, Tx completed 6-06. Clear PET 4-01-2008.
Thyroidectomy 5-9-08, resulting in permanent surgically-induced hypoparathyroidism and adrenal problems. Bummer.
