Causes of lung cancer
Lung cancer develops when a collection of cells in the lung tissue begins to grow and divide uncontrollably. This is usually due to damage to the cells' DNA. A number of agents have been linked to lung cancer; the most well known is tobacco smoking. About 90% of lung cancers are estimated to arise due to tobacco use. Other risk factors for the development of lung cancer include passive smoking, exposure to radon gas, asbestos exposure, air pollution, and certain lung diseases.
