How about this? My Dad has been undergoing chemo for lung cancer for many, many months. His PET scan yesterday just showed the active tumors on his lungs, kidneys and in his bones are GONE, although he still has what they believe to be scar tissue on his lungs. He still has 2 months of chemo to go. If the spots prove to be tumors, they are extremely optimistic that they can be removed relatively easily! And they're putting him on a different combo of chemo drugs, so they think he won't be as nauseous as he has been!!
