The most common causes of lung cancer

There are several factors, in connection with lung cancer. The most common causes are well known:

Nicotine

The cigarette is probably as close connection with the development of lung cancer. A person who smokes two packet of cigarettes per day or more of a chance on seven of the development of lung cancer. Those who smoke a carton of cigarettes per day over a period of twenty-five times as much to develop lung cancer, that a non-smoking restaurant. In addition, people who smoke cigars or pipe, five times more chances for the development of lung cancer a non-smoking restaurant.

The risk of lung cancer increases with the number of cigarettes smoked in the course of your life. Smoking damages the cells in the lungs. At the moment when you smoke, your lungs begin to heal themselves, by the damaged cells healthy, normal cells. Their risk of developing lung cancer falls almost immediately begins when the smoke. Every year, you do not smoke, your chances for the development of lung cancer cases. The fifteenth year, your chances of developing lung cancer are roughly the same as a person who never smoked.

Secondhand Smoke

Also known as passive smoking, the people who regularly secondary smoke have a higher risk of developing lung cancer, even if they do not smoke themselves. Studies have shown that those with a smoker have a higher risk of 24% of developing lung cancer that most non-smokers. The doctors believe that the lung cancer of about 3000 deaths per year in connection with the tobacco smoke in the ambient air.

Asbestos Exposure

Exhibition at the asbestos is a known cause of lung cancer and mesothelioma - cancer in the mucosa of the pleura lung cancer. Asbestos was frequently in the construction and products all days until the end of 1800, by the year 1960. Asbestos separates into fine fibers, silica are trapped in the lung tissue. The mesothelioma is inextricably linked to the asbestos exposure. There are no cases of mesothelioma among persons who have not been, or the asbestos in the workplace or on the environment. A non-smoker, asbestos has five times the risk of lung cancer, a non-smoker who was not suspended. Smoking increases the risk dramatically - that was a smoker asbestos is a risk for lung cancer, the 50 to 90 times higher than for non-smokers.

Radon

It is estimated that approximately 12% of deaths from lung cancer will be issued, radon, colourless, odourless gas that is a byproduct of the decay of uranium. The US Environmental Protection Agency believes that 15% of households in the United States have on the dangerous radon gas, from 15000 to 22000 deaths from lung cancer per year.

Air pollution

The scientists estimate that up to 1% of all deaths from lung cancer are on the air pollution. They feel that the longer the time very dirty air can increase the risks of developing lung cancer associated with passive smoking.
