Cancer is a leading case of death worldwide and accounted for seven million deaths (around 13% of all deaths) in2008.
Cancer is the uncontrolled growth and spread of cells. It can affect
almost any part of the body. The growths often invade surrounding tissue
and can metastasize to distant sites. Many cancers can be prevented by
avoiding exposure to common risk factors, such as tobacco smoke. In
addition, a significant proportion of cancers can be cured, by surgery,
radiotherapy or chemotherapy, especially if they are detected early.
Each year on 4 February, WHO supports International Union Against Cancer to promote ways to ease the global burden of cancer
