What are the causes of lung cancer?

Lung cancer is relatively common in our daily life, and it is also a disease with a high incidence and mortality rate. In fact, many causes of lung cancer are caused by details in life. Next, let us explore what are the causes of lung cancer.

1. Smoking According to a large number of survey data from various countries, the cause of lung cancer is closely related to smoking. The increase in the incidence of lung cancer is parallel to the increase in cigarette sales. Cigarettes contain a variety of carcinogens such as benzopyrene. Long-term smoking can cause bronchial mucosal epithelial cell hyperplasia, squamous cell carcinoma or undifferentiated small cell carcinoma, thereby causing lung cancer.

2. Air pollution is also one of the causes of lung cancer. The main reason is that in industrial and transportation-developed areas, the combustion of oil, coal, internal combustion engines, and asphalt road dust produces harmful substances such as benzopyrene carcinogenic hydrocarbons that pollute the atmosphere. Survey materials show that the incidence of lung cancer increases in areas with high concentrations of benzopyrene in the atmosphere.

3. Occupational factors are also a key factor in many people suffering from lung cancer. 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.

4. Chronic lung diseases such as tuberculosis, silicosis, and pneumoconiosis can coexist with lung cancer. The incidence of these lung cancers 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. On this basis, some lung cancer patients may develop into cancer.

The factors mentioned above are all causes of lung cancer. I hope this will help you understand the factors that cause lung cancer. I also hope that you can pay more attention to these aspects and do a good job in preventing lung cancer.
