Your dad definitely needs a second opinion. He was given a statistical answer on prognosis, not an individual one. Everyone is different. My wife is Stage IV, NSCLC, and was given 9 months. She is now 2 1/2 years out and still fighting the beast. She has had chemo and radiation, and she has had periods of non-sickness, which makes it all worth the treatments. She is still functional. Her oncologist is very on top of the latest and very aggressive in his approach. That is what we like. My hope is that you will hang onto the hope. Don
