Cancer is a generic term for a large group of diseases that can affect any part of the body. One defining feature of cancer is the rapid creation of abnormal cells that grow beyond their usual boundaries which can then invade adjoining parts of the body and spread to other organs. Cancer is one of the leading causes of death in the world, particularly in developing countries. In the WHO Western Pacific Region, it is estimated that close to 4.07 million new cases occurred in 2008 (2.31 million in men and 1.75 million in women). Almost 2.6 million people in the Region died from cancer that same year.
