Common causes of lung cancer

There are a variety of risk factors associated with lung cancer. The most common known causes are as follows:

Smoking cigarettes

Cigarette Smoking is probably the most closely related link to develop lung cancer.A person smokes two packets or more cigarettes per day is one in seven chance of developing lung cancer. people who smoke cigarettes a day one package with a twenty-five times more likely to develop lung cancer than non-smoker. In addition, those who smoke a pipe or cigar has five times more likely to develop lung cancer than non-smoker.

The risk for developing lung cancer increases with the number of cigarettes smoked for lifetime.Cigarette Smoking is damaging the cells into your lungs.As soon as you stop smoking, your lungs are themselves, healing by replacing the damaged cells with healthy normal cells. your risk for lung cancer begins fall almost immediately when you quit smoking. every year, who do not smoke, a further drop your chances of developing lung cancer. By the fifteenth year, your chances of developing lung cancer is about the same as those of a person who has never smoked.

Secondhand smoke

Also known as passive smoking, people who are exposed to secondhand smoke on a regular basis will have a higher risk of developing lung cancer, even if they themselves do not smoke. Studies have shown that people who live with a smoker have 24% higher risk of developing lung cancer than most non-smokers.Doctors estimate that about 3,000 lung cancer deaths linked to secondhand smoke.

Exposure to asbestos

Exposure to asbestos is another well-known cause of lung cancer and mesothelioma-cancer of the lining of the lungs pleural. Asbestos was widely used in construction and everyday products with the late 1800s through the 1960s.Asbestos fibre separates fine silica which become trapped in the tissues of the lungs. Mesothelioma is inextricably linked with exposure to asbestos. There are no reported cases of mesothelioma to people who were exposed to asbestos in the workplace or through their environment.Non-smoker who was exposed to asbestos is five times greater risk of lung cancer than non-smoker who were not exposed. Smoking increases the risk dramatically-smoker who was exposed to asbestos is a risk for lung cancer 50 to 90 times higher than that of non-smoker.

Radon Gas

It is estimated that approximately 12% of all lung cancer deaths can be attributed to radon gas, colorless, odorless gas that is a natural byproduct of tooth decay of uranium. U.S. Environmental Protection Agency estimates that as much as 15% of homes in the United States have unsafe levels of radon gas, representing every year 15,000 to 22,000 deaths from lung cancer.

Air pollution

Scientists estimate that as much as 1% of all lung cancer deaths due to air pollution. believe that prolonged exposure to very polluted air may increase the risks of developing cancer of the lungs to about the level of passive smoker.
