What are the specific causes of lung cancer

What are the causes of lung cancer? People have not given up the study of the causes of lung cancer, because the incidence of lung cancer has been increasing in recent years. So, what are the causes of lung cancer? In response to this question, we invite experts to give you a detailed introduction to the causes of lung cancer.

(I) Causes of lung cancer: Chronic lung diseases Causes of lung cancer such as 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 fibrous scar lesions of the lungs may cause squamous metaplasia or hyperplasia during the healing process. On this basis, some cases may develop into cancer.

(ii) Internal factors of the human body , such as family inheritance, reduced immune function, metabolic activity, endocrine dysfunction, etc., may also play a certain role in promoting the onset of lung cancer. These are all causes of lung cancer.

(III) Air pollution The incidence of lung cancer is high in industrially developed countries, 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 related 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. Survey materials show that the incidence of lung cancer is also higher in areas with high concentrations of benzopyrene in the atmosphere. Air pollution and smoking may promote each other and play a synergistic role in the incidence of lung cancer.

(IV) Occupational factors In the 1930s, there were reports of a high incidence of lung cancer in the Schneeberg mining area in Europe. After years of investigation and research, it is now recognized that long-term exposure to radioactive substances such as uranium and radium and their derivatives, carcinogenic hydrocarbons, arsenic, chromium, nickel, copper, tin, iron, coal tar, asphalt, petroleum, asbestos, mustard gas and other substances are all causes of lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma. This is also one of the causes of lung cancer.

The above is an introduction to the specific causes of lung cancer. It is for your reference only. I still hope that everyone can stay away from the above causes of lung cancer to avoid serious consequences for their lives. In addition, if you have any questions about the causes of lung cancer, please consult online experts!
