Lung Cancer

Causes of Lung Cancer

The basic Lung Cancer causes include the following


    • High incidence of Lung Cancer is closely associated with cigarette smoking, with around 90 percent of lung cancers resulting from Tobacco use. The risk of Lung Cancer rises with the number of cigarettes consumed over time; doctors refer to this risk in terms of smoking history or pack-years.

Asbestos fibers

    • Asbestos fibers, simply known as asbestos, are silicate fibers, which can remain in lung tissue following exposure to asbestos over a significant period of time. Contaminated workplace is a growing source of asbestos Fiber exposure, as asbestos has been commonly used in the past for both thermal and acoustic insulation materials. Exposure to asbestos results in both Lung Cancer and mesothelioma.

Radon Gas

    • Radon gas is a natural, chemically inert gas that is a result of uranium’s natural decay. This decays to form products which release a kind of ionizing radiation. Radon gas is a recognized cause of lung cancer, with an estimation of 10% of deaths.
    • Although most lung cancers are associated with cigarette smoking, the fact that not all smokers ultimately develop Lung Cancer indicates that other factors also play an important role in causing lung cancer, such as individual genetic susceptibility.

Lung Disease

  • The prevalence of some lung diseases, especially chronic obstructive pulmonary disease, is correlated with a significantly increased risk of developing different types of Lung Cancer even after the consequences of concomitant cigarette smoking are removed.
  • Each year, 3% of survivors of non-small cell lung cancers have an increased chance of developing Lung Cancer for a second time. 5% of survivors of small cell lung cancers have the risk of developing cancer again for the second time.
  • Air emissions from cars, factories, and power plants can increase the risk of developing Lung Cancer. Up to 3 percent of deaths from Lung Cancer are due to the inhalation of polluted air, and experts agree that prolonged exposure to highly polluted air can present a risk similar to passive smoking for Lung Cancer growth.
