summary

In our daily life, the causes of lung cancer are complex. We need to seize the time to treat it. It's not a single case. What's the matter with leukoplakia in the lungs of patients with the disease?, Now let's take a concrete look.

How does lobar have leukoplakia to return a responsibility?

First: smoking: the incidence rate of lung cancer is parallel to the increase in cigarette sales. Cigarette smoke contains a variety of carcinogens such as benzopyrene. Among the clinically confirmed lung cancer cases, more than 80% of them smoke more than 20 cigarettes a day for more than 30 years. In recent 20-30 years, the situation of smoking in China is very serious, and nearly 300 million people have the habit of smoking. Long term smoking can cause hyperplasia of bronchial epithelial cells, phosphorous epithelia, squamous cell carcinoma or undifferentiated small cell carcinoma. In addition, cooking smoke, which contains many harmful and even carcinogenic substances, can also cause lung cancer.

Second: air pollution: the incidence rate of lung cancer in developed countries is high, the city is higher than the rural area, the factory and mining area is higher than the residential area, mainly due to the pollution of the atmosphere by the harmful substances such as benzopyrene carcinogenic hydrocarbon and other harmful substances produced by burning petroleum and coal and internal combustion engine after the industrial and transportation developed areas. 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. The incidence rate of lung cancer and cigarette smoking may promote each other and play a synergistic role.

Third: 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, radium and other radioactive substances 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.

matters needing attention

Such as family heredity, decreased immune function, metabolic activity, endocrine dysfunction may also play a role in promoting the pathogenesis of lung cancer.
