What are the causes of lung cancer? Beware of several causes of lung cancer

The cause of lung cancer is often the first thing that comes to people's mind after they find out they have lung cancer, but many people don't know that people with lung cancer need to do a good job of treatment in order to inhibit the aggravation of the disease. Let's take a good look at the causes of lung cancer.

The main cause of lung cancer is smoking. 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. Cigarettes contain a variety of carcinogens such as benzopyrene. Experimental animals that inhale cigarette smoke or apply tar can induce respiratory and skin cancer. 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.

In addition, the incidence of lung cancer may also be caused by air pollution. In some industrially developed countries, the incidence of lung cancer is often higher, higher in cities than in rural areas, and higher in factory and mining areas than in residential areas. The main reason is that in industrial and transportation developed areas, the combustion of oil, coal and internal combustion engines and asphalt road dust produces harmful substances such as benzopyrene carcinogenic hydrocarbons that pollute the atmosphere. 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, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.

I believe everyone understands the most common causes of lung cancer introduced in the above article. Now that we know the causes of lung cancer, we must control them in a targeted manner to avoid this serious disease. A healthy attitude towards life will give us a bright future. I hope everyone can do this. If you want to know more, please consult an expert.
