Thank you guys for responding. I just don't know what to do. Anyone here with false activty on petscan? Right after radiation my cancer doctor said there was activity on vocal cords but he said not to fear, said it was normal. Could this be a normal reaction left from rads? What about floor of mouth? If it is cancer again, how could it be treated? More radiation to make matters worse? Surgery to remove what? Is there a quality of life after that? Do you think I should call my radiologist for an opinion? I'll be out of town tomorrow and deal with it the next. Thanks, Barbara
