Experts explain: Smoking is closely related to the cause of lung cancer

Lung cancer is a malignant tumor with a high incidence rate among male friends. The reason for this phenomenon is inseparable from male friends' love of smoking, because long-term smoking is likely to cause lung cancer. What are the common causes of lung cancer ? Let's ask experts to tell you about the common causes of lung cancer.

In general, the common causes of lung cancer are:

1. Smoking: According to a large number of survey data from various countries, the cause of lung cancer is closely related to smoking, and 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. Inhaling cigarette smoke or applying tar can induce respiratory and skin cancer in experimental animals.

2. Occupational factors: 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, petroleum, asbestos, mustard gas and other substances are common causes of lung cancer.

3. Air pollution: In industrial and transportation-developed areas, the combustion of petroleum, coal, internal combustion engines, and asphalt road dust produces harmful substances such as benzopyrene carcinogenic hydrocarbons, which are also common causes of lung cancer. Survey data show that in areas with high concentrations of benzopyrene in the atmosphere, the incidence of lung cancer is also increased. Air pollution and smoking may promote each other and play a synergistic role in the incidence of lung cancer.

The above is an explanation of the common causes of lung cancer. I believe everyone should have a preliminary understanding of this. For more questions about the causes of lung cancer, you can consult our online experts, who will answer them enthusiastically.
