Mickey, you seem to be in good hands and you're getting great advice from some of the real experts on this forum. I'm also available to speak/PM with you anytime about the effects of radiation treatment. I can't address chemo as I managed to avoid that.

Radiation knocked the stuffing out of me personally... but I've read of others for whom it wasn't as tough a ride.

Hang in there buddy!

Oh and to Charm's excellent advice about a thyroid test I'd add to be sure and visit a dentist before you start rads to assess the health of your teeth and gums. You'll likely be prescribed fluoride trays... you'll learn all about that from the tooth man, they're really not too bad at all (assuming your general dental health is good).
