What is the most common cause of lung cancer? Five high-risk factors for lung cancer

Lung cancer is a disease with a very poor prognosis in the respiratory system. For this disease, the recognized causative factors are smoking and industrial reasons. Therefore, those who smoke for a long time should pay attention to it in their daily lives. In addition, for this disease, there is no good treatment method except surgery in clinical practice. Therefore, it is best to receive treatment as soon as possible once you have lung cancer.

(1) Ionizing radiation: Exposure to radiation can cause a variety of malignant tumors, including lung cancer. People who are occupationally exposed to radiation have an increased risk of developing lung cancer. People can also be exposed to radiation in their daily lives, and some house decoration materials also contain substances that can generate radiation.

(2) Occupational carcinogens: Occupational carcinogens include inorganic arsenic compounds, asbestos, coal, smoke, tar, asphalt, smoke, mustard, dichloromethyl ether, vinyl chloride, nickel smelting, chromium, etc. Those who are exposed to occupational carcinogens for a long time at work have a significantly increased risk of developing lung cancer.

(3) Air pollution: With the progress of society and the development of industry, the production and use of many industrial raw materials and products containing carcinogens have increased, which has not only increased the number of lung cancer cases among workers directly exposed to them, but also aggravated the degree of air pollution caused by carcinogens. Exhaust gas from cars, asphalt used in road and house construction, etc. all contain carcinogens, making air pollution increasingly serious.

(4) Smoking: It is now generally recognized that smoking is an important risk factor for lung cancer. Tobacco leaves and smoke contain a variety of ulcer-causing and cancer-promoting agents such as tar and benzophenone. It is estimated that about 85% of lung cancer is related to smoking, and smokers are 12-22 times more likely to develop lung cancer than non-smokers.

(5) Home 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 home environment. The incidence of lung cancer in women may be related to long-term inhalation of cooking fumes.

The above experts have explained so much about the causes of lung cancer, but clinically the most common cause of lung cancer is still smoking, but genetic factors are not ruled out. As our environmental pollution becomes more serious, the quality of the air we breathe has also decreased. Therefore, we should pay attention to it in daily life and try not to contact the source of the disease.
