What are the causes of lung cancer? Introduction to 4 causes of lung cancer

Among various cancers, everyone knows that lung cancer is the most common malignant tumor. Although modern medical technology can help patients prolong their lives, it cannot solve the fundamental problem. Why do cancer cells appear in our lungs? If you want to know, let's learn about it together! 1. Due to occupational reasons. This is because some jobs require daily contact with radioactive substances such as radium and uranium, asbestos, petroleum, asphalt, coal tar, arsenic, chromium, nickel, copper, tin, and other carcinogenic substances. These are the causes of lung cancer. People who work in this area should pay more attention to the prevention of lung cancer. 2. Due to chronic lung diseases. Some people do not know that they have chronic lung diseases, which may also be the cause of lung cancer, such as pneumoconiosis, silicosis, and tuberculosis. Once you have these lung diseases, the chance of lung cancer will be very high. If you want to prevent lung cancer, you must also be alert to the occurrence of these diseases. Moreover, if you suffer from lung fibrosis scar lesions or non-bronchial chronic inflammation, you will slowly develop lung cancer, which is also one of the causes of lung cancer. 3. Due to air pollution. The prevention of lung cancer requires improving air pollution. The incidence of lung cancer in many industrially developed countries is extremely high, and it is higher in cities than in rural areas, and higher in factory and mining areas than in residential areas. The main cause of lung cancer in this regard 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. 4. Family environment. The decoration materials of the house and the fumes produced when cooking contain a lot of ulcer-causing substances. Passive smoking caused by family members smoking can also pollute the family environment. The cause of lung cancer in women may be related to long-term inhalation of cooking fumes. For a disease like lung cancer, if we can understand some of the causes, we can do a good job of prevention in our daily lives. Good prevention can greatly reduce the harm of this disease to our health. I hope that after understanding the above knowledge, everyone can pay attention to the disease of lung cancer.
