Common Causes Of Lung Cancer
August 7th, 2010 . by stop smoking guestThere are a numerous risk factors which 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 creating lung cancer. A one that smokes two packs or more of cigarettes per day has a one in seven likelihood of growing lung cancer. Those that smoke one pack of cigarettes per day have a twenty-five instances greater likelihood of growing lung cancer than a non-smoker. In addition, those those that smoke a pipe or cigar have a 5 times greater chance of developing lung most cancers than a non-smoker.
The threat of creating lung cancer increases with the number of cigarettes smoked over your lifetime. Cigarette smoking damages the cells in your lungs. The moment you cease smoking, your lungs start healing themselves, replacing damaged cells with healthy, normal cells. Your threat of developing lung most cancers begins decreasing almost immediately while you quit smoking. Every 12 months that you do not smoke, your probabilities of developing lung most cancers drop further. By the fifteenth year, your probabilities of developing lung most cancers are about the identical as these of a person who has never smoked.
Secondhand Smoke
Also often called passive smoking, people exposed to secondhand smoke on a regular basis will have the next 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 growing lung most cancers than most non-smokers. Doctors estimate that about 3000 lung most cancers deaths a yr are related to secondhand smoke.
Asbestos Exposure
Exposure to asbestos is one other well-known explanation for lung most cancers and mesothelioma - cancer of the pleural lining of the lungs. Asbestos was widely used in construction and everyday products in the late 1800s by means of the 1960s. Asbestos separates into advantageous silica fibers that turn into trapped within the tissues of the lungs. Mesothelioma is inextricably linked to asbestos exposure. There are no reported instances of mesothelioma in people who were not uncovered to asbestos either in the workplace or through their environment. A non-smoker who was uncovered to asbestos has a five times greater risk of growing lung most cancers than a non-smoker who was not exposed. Smoking increases the danger dramatically - a smoker who was exposed to asbestos has a threat of growing lung cancer that is 50 to 90 times higher than that of a non-smoker.
Radon Gas
It is estimated that about 12% of lung cancer deaths will be attributed to radon gas, a colorless, odorless gas that could be 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 most cancers deaths are attributable to air pollution. They believe that extended exposure to very polluted air can increase the dangers of creating lung most cancers to about the levels of a passive smoker.
