Smoking is the main cause of lung cancer

Smoking is the main cause of lung cancer, but it seems that many people do not pay attention to this. More and more people do not pay attention to it and continue to smoke, which leads to serious diseases. So what are the causes of lung cancer ? The details are as follows.

The causes of lung cancer include the following:

(1) Air pollution: With the progress of society and the development of industry, the production and use of many industrial raw materials and products containing carcinogens have increased, which not only increases the number of workers directly exposed to lung cancer, but also aggravates the degree of air pollution caused by carcinogens. The exhaust gas discharged by cars, asphalt used in road and house construction, etc. all contain carcinogens, making air pollution increasingly serious. The incidence of lung cancer in industrially developed countries is higher than that in industrially backward countries, higher in cities than in rural areas, higher in large cities than in medium and small cities, and higher in urban areas than in suburbs. This may be related to the more serious air pollution in cities, which is the cause of lung cancer.

(2) Smoking: It is now generally recognized that smoking is the main cause of lung cancer. Tobacco leaves and smoke contain a variety of ulcer-causing and cancer-promoting agents such as tar and benzophenone. It is estimated that about 85% of lung cancer is related to smoking, and smokers are 12-22 times more likely to develop lung cancer than non-smokers.

(3) Home environment: The decoration materials of the house and the fumes produced when cooking contain a lot of ulcer-causing substances. Passive smoking caused by family members smoking can also pollute the home environment. The incidence of lung cancer in women may be related to long-term inhalation of cooking fumes.

(4) Occupational carcinogens: Occupational carcinogens include organic arsenic compounds, asbestos, coal, smoke, tar, asphalt, smoke, mustard, dichloromethyl ether, vinyl chloride, nickel smelting, chromium, etc. Those who are exposed to occupational carcinogens for a long time at work have a significantly increased risk of developing lung cancer, which is the cause of lung cancer.

The above is the explanation given by experts on the causes of lung cancer. I hope it can help you answer your questions. Experts remind everyone that if you suffer from any disease in your daily life, you must not delay treatment. This is very dangerous. Some diseases will worsen or cause other diseases.
