What are the causes of lung cancer? Pay attention to the three high-risk factors of lung cancer

Smoking is currently the most common cause of lung cancer. It is important to know that smoke can cause long-term chronic irritation to the lungs. At the same time, it is also important to know that smoke is an extremely acidic substance. Long-term smoking may cause acidification of the human body. The following is an introduction to the causes of lung cancer:

1. Experts say that smoking is one of the important causes of lung cancer. All data show that there is a significant relationship between lung cancer and smoking, because tobacco contains a large amount of carcinogens. The incidence of lung cancer in smokers is ten times higher than that of non-smokers, and the incidence is even higher in heavy smokers, which is twice as high as that of non-smokers. Among clinically diagnosed lung cancer cases, patients who smoke more than 20 cigarettes a day for 30 years have an 80% chance of developing lung cancer.

2. Occupational factors are also related to the occurrence of lung cancer. Long-term exposure to some radioactive substances or their derivatives can lead to lung cancer, such as arsenic, chromium, nickel, copper, tin, iron, coal tar, asphalt, petroleum, asbestos, mustard gas, etc. Therefore, everyone must pay attention to such problems.

3. Air pollution is also one of the important factors for the high incidence of lung cancer. The incidence of lung cancer in cities with serious pollution is much higher than in rural 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. Survey materials show that the incidence of lung cancer increases in areas with high concentrations of benzopyrene in the atmosphere. At the same time, in cities with serious air pollution, the probability of smokers suffering from lung cancer increases greatly.

We must also pay enough attention to some chronic lung diseases. For example, common diseases such as lung stones or pneumonia can directly cause lung cancer, but they are generally caused by long-term chronic stimulation. It should be noted that the incidence of lung cancer in this group of people is significantly higher than that of normal people.
