Hi Wayne,
Good luck with the radiation treatments. As you no doubt have learned from others at the OCF, radiation is no walk in the park but is doable.
Try to take a look at the OCF section on radiation at:
http://www.oralcancerfoundation.org/facts/radiation.htm

Also, do a search of the OCF board for "PEG" or "feeding tube" to read about others' experiences with and without a tube. I personally found it to be real lifesaver and wished I'd had it put in before my treatments started. Your mileage may vary.

Since radiation will burn up your taste buds for a while, you should eat your favorite foods before the treatments begin, if your surgery permits you to do that. Best, Sheldon
