What are the four major factors that easily lead to the occurrence of lung cancer?

Nowadays, many teenagers have started smoking. Smoking will seriously affect the growth of teenagers, and excessive smoking can easily cause teenagers to suffer from lung cancer. In recent years, the incidence of lung cancer has been increasing. So what are the reasons that can cause lung cancer to appear in people's lives?

Experts introduced four causes of lung cancer as follows:

First, due to occupational reasons. This is because some jobs require daily contact with radioactive substances such as radium and uranium, as well as mustard gas, asbestos, petroleum, asphalt, coal tar, arsenic, chromium, nickel, copper, tin, and other carcinogenic substances, which are all causes of lung cancer. People engaged in such work should pay more attention to the prevention of lung cancer.

Second, due to chronic lung diseases. Some people suffer from chronic lung diseases without knowing it, which may also be the cause of lung cancer, such as pneumoconiosis, silicosis, tuberculosis, etc. Once you have these lung diseases, the chance of lung cancer will be very high. If you want to prevent lung cancer, you must also be alert to the occurrence of these diseases. Moreover, if you suffer from lung fibrosis scar lesions or non-bronchial chronic inflammation, it will slowly turn into lung cancer, which is also one of the causes of lung cancer.

Third, due to air pollution. The prevention of lung cancer requires improving air pollution. The incidence of lung cancer in many industrially developed countries is extremely high, and it is higher in cities than in rural areas, and higher in factory and mining areas than in residential areas. The main cause of lung cancer is due to the pollution of the atmosphere by harmful substances such as benzopyrene carcinogenic hydrocarbons produced by the combustion of oil, coal and internal combustion engines and asphalt road dust in industrial and transportation-developed areas.

Fourth, the family 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 family environment. The cause of lung cancer in women may be related to long-term inhalation of cooking fumes.

According to the survey, most lung cancer patients suffer from the disease due to the above four reasons. Therefore, now that people know the causes of lung cancer, they should prevent the above causes from appearing in their lives. At the same time, they should stay away from friends who smoke and refuse secondhand smoke, which can further reduce the possibility of developing lung cancer.
