Experts tell you the high-risk factors that induce lung cancer

According to recent surveys and statistics, 600,000 people die of lung cancer in China every year, and the incidence of lung cancer increases by 26.9% every year. So what are the high-risk factors for lung cancer ? Let's talk about the high-risk factors for lung cancer.

Generally, the high risk factors for lung cancer are:

1. Smoking. In 1922, Hampeln found that continuous smoking and inhalation of dust can stimulate bronchial epithelium and induce lung cancer. In 1924, Moller applied tar to the back of rabbits and found that the chance of inducing lung cancer increased slightly. Smoking is currently considered to be the most basic high-risk factor for lung cancer. There are more than 3,000 chemical substances in tobacco, and polycyclic aromatic hydrocarbon compounds (such as benzopyrene) have strong carcinogenic activity. It can act on certain special enzymes in human tissues (especially lung tissues) to produce mutations in cell molecular structures (such as DNA), and there may be mutations in K-ras.

2. Occupational and environmental exposure. It is estimated that up to 15% of lung cancer patients have a history of environmental and occupational exposure. There is sufficient evidence to prove that the following 9 industrial ingredients increase the chance of inducing lung cancer: byproducts of aluminum products, arsenic, asbestos, bis-chloromethylether, chromium compounds, coke ovens, mustard gas, nickel-containing impurities, and vinyl chloride. Long-term exposure to substances such as beryllium, cadmium, silicon, and formalin will also increase the incidence of lung cancer. In addition, air pollution, especially industrial waste gas, is a high-risk factor for lung cancer.

3. Radiation. Uranium and fluorite miners are exposed to inert gas radon, decay byproducts of uranium, etc., and their chance of developing lung cancer is significantly higher than other people. However, people exposed to ionizing radiation will not increase the incidence of lung cancer.

4. In patients with chronic lung infections, such as tuberculosis and bronchiectasis, the bronchial epithelium may metaplasia into squamous epithelium during the chronic infection process, eventually inducing lung cancer, but this type of situation is relatively rare.

5. Internal factors, including family, genetic and congenital factors, as well as reduced immune function, metabolic and endocrine dysfunction, may also be high-risk factors for lung cancer.

6. Air pollution. The incidence of lung cancer is high in industrially developed countries, higher in cities than in rural areas, and higher in factory and mining areas than in residential areas. The main reason is that in industrially and traffic-developed areas, the combustion of oil, coal, and internal combustion engines, as well as asphalt road dust, produces harmful substances such as benzopyrene carcinogenic hydrocarbons that pollute the atmosphere. Survey materials show that areas with high concentrations of benzopyrene in the atmosphere also have higher incidences of lung cancer. 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 high-risk factors that induce lung cancer. I believe everyone has some understanding of the high-risk factors that induce lung cancer. For more questions about the high-risk factors that induce lung cancer, you can consult our experts.
