What causes lung cancer?

Smoking has been recognized as an important risk factor for lung cancer. The higher the amount of smoking, the longer the years of smoking, the earlier the age of starting smoking, and the higher the mortality of lung cancer. The risk of lung cancer in smokers decreased gradually with the extension of smoking cessation years. Smoking cessation lasted for 15 years before it was similar to that of non-smokers. Passive smoking is also easy to cause lung cancer.

Air pollution includes indoor small environment and outdoor large environment pollution. Such as indoor passive smoking, fuel combustion and cooking process may produce carcinogens. There are carcinogens in automobile exhaust gas, industrial exhaust gas and highway asphalt in cities, and the main carcinogen is benzopyrene.
