A promising immunotherapy drug for lung cancer, Opdivo, was just approved. It's not a magic bullet, but it is one more weapon in the arsenal against lung cancer. See http://www.cancer.org/cancer/news/news/fda-approves-opdivo-nivolumab-for-lung-cancer for a brief summary.
My hope has always been to stay healthy long enough to be eligible for whatever the next new treatment will be. With more immunotherapy drugs in clinical trial right now, every day the picture gets a little brighter. :-)
