What is Cancer? Cancer develops when cells in a part of the body begin to grow out  of control. Although there are many kinds of cancer, they all start  because of out-of-control growth of abnormal cells.  Normal body cells grow, divide, and die in an orderly fashion.  During the early years of a person's life, normal cells divide more  rapidly until the person becomes an adult. After that, cells in most  parts of the body divide only to replace worn-out or dying cells  and to repair injuries.  Because cancer cells continue to grow and divide, they are  different from normal cells. Instead of dying, they outlive normal  cells and continue to form new abnormal cells.  Cancer cells develop because of damage to DNA. This substance  is in every cell and directs all its activities. Most of the time when  DNA becomes damaged the body is able to repair it. In cancer
