Can bronchial asthma turn into lung cancer

Reason 1: according to a large number of investigation data in various countries, the etiology of lung cancer is closely related to smoking paper cigarettes. The increase in lung cancer incidence rate is parallel to the increase in cigarette sales. Cigarette contains benzopyrene and other carcinogens. Inhalation of cigarette smoke or application of tar can induce respiratory tract and skin cancer in experimental animals. The incidence rate of lung cancer is 10 times higher than that of non-smokers. The incidence rate of smoking is higher than that of non smokers, which is 20 times higher than that of non-smokers.

Reason two: air pollution: the incidence rate of lung cancer in developed countries is high, the city is higher than the rural area, and the factory and mining area is higher than the residential area. The main reason is that the pollution of the atmosphere is caused by harmful substances such as benzopyrene carcinogenic hydrocarbon and other harmful substances produced by burning petroleum and coal and internal combustion engines after the burning of oil and coal and internal combustion engines. The survey materials showed that the incidence rate of lung cancer was also increased in the area where the concentration of benzopyrene in the atmosphere was high. Air pollution and cigarette smoking may increase the incidence rate of lung cancer and play a synergistic role.

Reason three: occupation factor: in the 30s of this century, there were reports of high incidence rate of lung cancer in European Schneeberg mining area. After years of investigation and research, it has been recognized that long-term exposure to uranium, pitch, chromium, mustard gas, copper, coal tar, radium and other radioactive substances and their derivatives, asbestos, carcinogenic hydrocarbons, petroleum, tin, iron, nickel, arsenic and other substances can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.
