@rlf66attnet , With the recent clinical advances, 'Lung Cancer' is now known to include many different types of cancer. Knowing the specific type will help your oncologist to select the most appropriate treatment. I'm sorry that you are facing this. I know how scary it can be. There have been so many advances in treatments. The outlook for us is better than ever. There are more and more of us living longer, even with stage IV disease. Will you let us know what you learn at your appointment?
