What are the risk factors for lung cancer? 3 things you need to know about the causes of lung cancer

Lung cancer is a common malignant tumor. In recent years, more and more people have been suffering from this disease, even some very young people. Once symptoms of lung cancer are discovered, it is usually in the late stage and the possibility of recovery is questionable. Therefore, it is very important to do early prevention for this type of disease. Here we will introduce to you the causative factors of lung cancer that you should be highly vigilant about.

Lung cancer risk factors should be highly vigilant

1. Occupational factors

Medical research has found that some people who are exposed to toxic compounds for a long time are at high risk of lung cancer. For example, 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 may cause lung cancer and should take protective measures.

2. Long-term smoking

The incidence of lung cancer is positively correlated with smoking. Tobacco burning produces a variety of carcinogens such as benzopyrene. Experimental animals that inhale cigarette smoke or apply tar can develop respiratory and skin cancer. In short, long-term smoking leads to a high incidence of lung cancer.

3. Air pollution

This has become one of the most important factors inducing lung cancer. Air pollution generally seriously harms people's living environment, especially in some industrial and transportation developed areas. The combustion of oil, coal and internal combustion engines and asphalt road dust produce harmful substances such as benzopyrene carcinogenic hydrocarbons that pollute the atmosphere. People living in cities should pay attention to environmental protection.

4. Impact of chronic lung diseases

Patients suffering from tuberculosis, silicosis, pneumoconiosis, etc., may develop lung cancer if not cured for a long time, so they should be highly vigilant.
