Liz thank you so much for your kind response. He did not have a PET prior to surgery. Just CAT. I hope that it is what you said only that his surgeon said symptoms are worrisome. I noticed that your dear husband had it hit hard and furious on the reoccurence. This disease just makes me SCREAM! I am flying up there this noon time to give my sister a break. I just want to be there with him since he is a widower and lives alone:(
