Background: Lung Cancer, like all other cancers, results from an acquired abnormality in the body's basic unit of life, the cell. Normally, the body maintains a system of control mechanisms for cell growth, so that cells divide to produce new cells only when new cells are needed. Disruption of this control system results in an uncontrolled division and proliferation of cells that eventually forms a mass known as a tumor.
