My dad had pancreatic islet-cell cancer. After a local surgeon determined that the tumor was inoperable, a heroic team at the Mayo took it out. Several years later he developed cancer in his liver, which is now largely nonfunctional.<p>He just turned eighty, so I don't think a transplant was ever under consideration, but I wonder how he'd be if, say, five years ago I could have given him part of mine. I doubt he would have accepted it either.<p>I'm happy to say that he was recently kicked out of hospice for being too healthy, but the chances of him making it to eighty-one are very slim.
