Good for you, Donna! You certainly do NOT need any added stress - especially one that runs all over the house peeing on everything. Re hair loss with radiation, my son's treatment involved radiation only and the hair only fell out in the beard area and at the spots in back of his neck where the beams were directed but it all came back. And since your Mom doesn't have a beard. . . why would she need a wig??? You are right about the positive thoughts and even pretending happy thougts. It really does work!! I call it positive visualization. Keep on keeping on, Donna.
