How is lung cancer caused? The four high-risk factors are most likely to induce lung cancer

What are the causes of lung cancer? In recent years, more and more people have been diagnosed with lung cancer. Many people have developed a panic about this disease, so it is necessary for everyone to understand some common knowledge about lung cancer, which is also helpful for preventing lung cancer. Let's take a look at the causes of lung cancer.

(1) Human endogenous factors such as family heredity, reduced immune function, metabolic activity, endocrine dysfunction, etc. may also play a certain role in promoting the incidence of lung cancer.

(II) Although it is not clear what factors are related to the cause of lung cancer, according to a large number of surveys in 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. The incidence of lung cancer in smokers is 10 times higher than that of non-smokers, and the incidence is even higher in those who smoke a lot, 20 times higher than that of non-smokers.

At the end of this century, with the increasing number of female smokers in Western European countries, the incidence of lung cancer in female patients has also increased significantly. Long-term smoking can cause bronchial mucosal epithelial cell hyperplasia, squamous cell carcinoma or undifferentiated small cell carcinoma. Although non-smokers can also suffer from lung cancer, adenocarcinoma is a more common cause 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 reason is that the atmosphere in industrially and traffic-developed areas is polluted by harmful substances such as benzopyrene, a carcinogenic hydrocarbon, produced by the combustion of petroleum, coal, and internal combustion engines, as well as asphalt road dust.

(IV) Occupational factors. After years of investigation and research, 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 the cause of lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.

The above is an introduction to the causes of lung cancer. I hope you can get the help you need from it. Experts point out that you should not think that you are going to die as soon as you hear about cancer. As long as you actively cooperate with the doctor's treatment, the disease can still be cured. Don't have too much psychological pressure. Keep a normal mind and you will recover your health soon.
