Didier, I am so very, very sorry for you and your parents. What a low blow and gosh awful timing, too. If it helps, please know that I am very angry on your behalf! I guess there must be a group of people who talk about lung cancer as we talk about OC, who might be able to help you understand what to expect about your dad's condition. I had two older friends with non-operable lung cancer. One had a good five years and we lunched and shopped, and it was only for a couple of months at the end when she was bed ridden. The other had a pretty good three years, so this may not be an immediate thing. When you get over your shock, you will need more information from his doctor for sure. Know for certain that we will be here to send you strength for the weeks, months, and hopefully years ahead.
