I was looking for reasons people who have terminal cancer choose to fight to live with chemo and radiation. Going through all that for a little more time, Is it worth it? To me they endure so much more pain and go through more of an emotional roller coaster by choosing to do treatment. Their families also go through the pain and agony, only to lose the person they love. I want to understand what the will to live is, and why we keep fighting when there is no hope.
