What are the causes of lung cancer? Be careful of these risk factors of lung cancer

Lung cancer has endangered people's lives and health. Many patients are still very confused about the causes of lung cancer. Doctors say that the causes of lung cancer are mainly caused by bad habits in life, such as heavy smoking and drinking, and exposure to harmful chemicals. These are the culprits of lung cancer. Today, experts will share with you the causes of lung cancer.

What are the causes of lung cancer? Experts say that there are many pathogenic factors of the disease in life, and it is the interaction of many factors that leads to the occurrence of lung cancer.

Among them, according to a large number of surveys in various countries, the cause of lung cancer is closely related to smoking.

The increase in the incidence of lung cancer is in parallel with the increase in cigarette sales. Cigarettes contain a variety of carcinogens such as benzopyrene. Experimental animals that inhale cigarette smoke or apply tar can induce respiratory and skin cancer. The incidence of lung cancer in smokers is 10 times higher than that of non-smokers, and the incidence is even higher in those who smoke heavily, 20 times higher than that of non-smokers.

In addition, the incidence of lung cancer is often affected by air pollution.

Foreign researchers have found that the incidence of lung cancer is often higher in some industrially developed countries, higher in cities than in rural areas, and higher in factory and mining areas than in residential areas. The main reason is that in industrially and transportation-developed areas, the combustion of oil, coal, and internal combustion engines, as well as asphalt road dust, produce harmful substances such as benzopyrene carcinogenic hydrocarbons that pollute the atmosphere.

After years of investigation and research, it is now recognized that long-term exposure to radioactive substances such as uranium, radium and their derivatives, carcinogenic hydrocarbons, arsenic, chromium, nickel, copper, tin, iron, coal tar, asphalt, petroleum, asbestos, mustard gas and other substances can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.

The above is a detailed introduction about the causes of lung cancer. I hope that healthy people will actively prevent the occurrence of lung cancer, stay away from smoking and radioactive chemicals, take practical actions to prevent lung cancer, control the harm caused by lung cancer to humans, have a healthy life, and wish lung cancer patients a speedy recovery.
