Welcome, David. I'm in a similar position, with a wife who was diagnosed with NSCLC, Stage IV, except she had many bone mets from the lung cancer. She is now in her 27th month since diagnosis, so hang in there and hang onto your hope. There are many survivors on this website. Your wife's memory problems can be due to the major stress that comes with knowing you have cancer. Cancer is a family disease -- all suffer -- and all get weird from time to time. All part of this journey on a road we didn't want to be on. But, we are on it, and the main thing is how we handle the journey. We are here for you and your wife, so take full advantage of the family here. Best to you both. Don
