We have learned a lot about lung cancer and know how to prevent and treat lung cancer, so what kind of people are prone to lung cancer? Today, we will introduce them to you. 1. Long-time smokers Those who smoke more than 20 cigarettes a day. Cigarettes contain substances harmful to human body, especially tar and nicotine, which are strong carcinogens. The toxic substances in cigarettes also gradually destroy some villi and increase the secretion of mucus, so chronic diseases occur in the lungs, which can easily lead to bronchitis and cancer, therefore, the chance of lung cancer is many times higher for regular smokers than others. 2.People who live in areas with serious air pollution People who live in areas with serious environmental pollution for a long time have been found that 80% of malignant tumors are induced by environmental factors, and the presence of a large number of carcinogenic substances in the environment where human beings live is the main reason for the rising incidence of cancer year by year. In general, the incidence of lung cancer rises gradually among people older than 55 years old and reaches its peak when they are 75-80 years old. 4.People who are exposed to radiation for a long time The risk of lung cancer in these people is higher than that of the general population, such as those who work in metal mines and are exposed to inorganic arsenic, asbestos, chromium, nickel, etc. for a long time and lack of protection. Through the above introduction, I believe we have an understanding of the people who are prone to lung cancer, so we must do our best to prevent it and keep it away from us as much as possible.
