They had discussed doing that treatment with my dad. He is so claustraphobic, let me put it this way, he can barley wash his hair under the shower claustraphobic. Imagine when he had to do Pet scans as well. That was his only fear. Not cancer, not radiation. I think if you just discovered it you'll be fine. Ask for Adavant. Works really good. The day I took him for his PET he thought we were in my car the entire trip instead of his. Breathe deeply, relax, and good luck.
