I am so happy for you and your dad. We need wonderful stories like this to keep us going through all the challenges. I was wondering if you could explain how they look at the lymph nodes and the tumors for comparison purposes. My dad's ct scans always show the lymph nodes affected by the stomach cancer, however the tumor in his stomach only showed up with an endoscopy it was about the size of a quarter. His last ct scan showed no change in the lymph nodes with slightly less fluid in the lung cavity - but it has not spread to the lungs, even though it is in the lymph system. He did have a metastasis to the lymph nodes on the side of his neck which has shrunk considerably since he began treatment in January. Everyone just keeps telling us he is doing well, but this is very serious. Is the only way to tell if his tumor has shrunk to go through another endoscopy? I wish your dad continued success with this thing.
