One interesting new line of research is suggesting that cancer in the
elderly is caused by the immune system wearing out. The theory is that
cancer cells appear in the body all your life, but are usually killed
off by the immune system. The cancer disease only appears when the
immune system fails or there is a huge increase in cancer cells which
overwhelms the immune system (e.g.radiation, or asbestos, etc.).
