Analyzing the three main causes of lung cancer

It is understood that the incidence of lung cancer is relatively high in industrially developed countries, which shows that the development of industrialization is related to the cause of lung cancer and may be one of the causes of lung cancer. People need to pay more attention to preventing lung cancer. What are the other common causes of lung cancer ? Let's talk about the common causes of lung cancer.

In general, the common causes of lung cancer are:

1. Air pollution

In industrial and transportation-developed areas, the atmosphere is polluted by harmful substances such as benzopyrene carcinogenic hydrocarbons produced by the combustion of oil, coal, internal combustion engines, and asphalt road dust, which is a common cause of lung cancer. Survey data show that the incidence of lung cancer is also increased 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.

2. Occupational factors

In the 1930s, there were reports in the literature about the high incidence of lung cancer in the Schneeberg mining area in Europe. After years of investigation and research, it is now generally 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 can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma. This is a relatively common cause of lung cancer.

3. Chronic lung diseases

It is also a common cause of lung cancer. Tuberculosis, silicosis, pneumoconiosis, etc. 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 bronchus and pulmonary fibrosis scar lesions may cause squamous metaplasia or hyperplasia during the healing process. On this basis, some cases may develop into cancer.

The above analysis is about the common causes of lung cancer, and I hope it will be helpful to everyone. If you still have questions about the causes of lung cancer, you can consult our online experts, who will give you a satisfactory answer.
