What is Lung cancer?

Lung cancer may be defined as a type of cancer that develops in cells or tissues of the lung, usually in the cells that line the air passages. This form of cancer mostly arises due to Cigarette smoking, tobacco consumption, being exposed to substances such as asbestos, breathing secondhand smoke, etc.
