Cancer has affected the lives of each and every one of us alive today. Many people have known someone with cancer, yet even those who haven’t have been bombarded with constant reminders of its terrible threat. Although cancer is often referred to as a single condition, it actually consists of more than 100 different diseases, all characterized by the uncontrolled growth, reproduction, and spread of abnormal body cells. All of these diseases are individually unique, yet the basic processes that produce cancers are very similar (Ruddon, 1995).
