Chronic lung diseases are common causes of lung cancer

The incidence of lung cancer has been rising recently, and some occupational factors are common causes of lung cancer. What causes of lung cancer should we pay attention to? In order to learn more about the causes of lung cancer, the following is an introduction to the causes of lung cancer by experts.

First, chronic lung diseases are common causes of lung cancer. For example, tuberculosis, silicosis, and pneumoconiosis can coexist with lung cancer. The incidence of cancer in these cases is higher than that of normal people. In addition, chronic inflammation of the lung bronchi and pulmonary fibrosis scar lesions may cause squamous metaplasia or hyperplasia during the healing process.

Second, air pollution is also a common cause of lung cancer. Survey data show that areas with high concentrations of benzopyrene in the atmosphere also have a higher incidence of lung cancer. Air pollution and smoking may promote each other and play a synergistic role in the incidence of lung cancer.

Third, smoking is also one of the causes of lung cancer. According to a large amount of survey data from various countries, the cause of lung cancer is closely related to smoking.

Fourth, internal factors of the human body, such as family heredity, reduced immune function, metabolic activity, endocrine dysfunction, etc. may also play a certain role in the incidence of lung cancer and are all causes of lung cancer.

5. Occupational factors. It is now generally 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.
