Common Causes Of Lung Cancer

Common Causes Of Lung Cancer



There are a​ various risk factors that are linked to​ lung cancer. the​ most common known causes are as​ follows:

Cigarette Smoking
Cigarette smoking is​ probably the​ most closely related link to​ developing lung cancer. a​ person who smokes two packs or​ more of​ cigarettes per day has a​ one in​ seven chance of​ developing lung cancer. Those that smoke one pack of​ cigarettes per day have a​ twenty-five times greater chance of​ developing lung cancer than a​ non-smoker. in​ addition, those people that smoke a​ pipe or​ cigar have a​ five times greater chance of​ developing lung cancer than a​ non-smoker.

The risk of​ developing lung cancer increases with the​ number of​ cigarettes smoked over your lifetime. Cigarette smoking damages the​ cells in​ your lungs. the​ moment you stop smoking, your lungs begin healing themselves, replacing damaged cells with healthy, normal cells. Your risk of​ developing lung cancer begins decreasing almost immediately when you quit smoking. Every year that you do not smoke, your chances of​ developing lung cancer drop further. By the​ fifteenth year, your chances of​ developing lung cancer are about the​ same as​ those of​ a​ person who has never smoked.

Secondhand Smoke
Also known as​ passive smoking, people exposed to​ secondhand smoke on a​ regular basis will have a​ higher risk of​ developing lung cancer, even if​ they do not smoke themselves. Studies have shown that those who live with a​ smoker have a​ 24% greater risk of​ developing lung cancer than most non-smokers. Doctors estimate that about 3000 lung cancer deaths a​ year are related to​ secondhand smoke.

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

Radon Gas
It is​ estimated that about 12% of​ lung cancer deaths can be attributed to​ radon gas, a​ colorless, odorless gas that is​ a​ natural byproduct of​ the​ decay of​ uranium. the​ U.S. Environmental Protection Agency estimates that as​ many as​ 15% of​ homes in​ the​ United States have unsafe levels of​ radon gas, which will account for​ 15,000 to​ 22,000 deaths from lung cancer annually.

Air Pollution
Scientists estimate that as​ many as​ 1% of​ all lung cancer deaths are attributable to​ air pollution. They believe that prolonged exposure to​ very polluted air can raise the​ risks of​ developing lung cancer to​ about the​ levels of​ a​ passive smoker.
