Geez Ed,
That's a mouthful. Is the bottom line here radiation treatment damages body tissues so it is even more important to get more physical exercise that gets blood flowing throughout the body, particularly the areas damaged by radiation?

In that case, my multiple daily neck stretching exercises that I do to minimize the muscle tightness and cramping also get more blood flowing through there as an added benefit.
