Who are the most susceptible to lung cancer? These four types of people need to pay attention

People who are most susceptible to lung cancer mainly include: middle-aged and elderly people, long-term smokers, people who are exposed to radiation for a long time, and patients with chronic lung diseases.

1. Middle-aged and elderly people <br/>The incidence of lung cancer is related to age factors, and the middle-aged and elderly are the high-risk group for lung cancer. The incidence of lung cancer gradually increases after the age of 55 and reaches a peak around 75 to 80 years old.
2. Long-term smokers <br/>Tobacco contains tar, nicotine and other strong carcinogenic substances. Long-term smoking will damage the villi in the lungs, increase the mucus in the lungs, and easily infect bronchitis and other lung diseases leading to cancer. The incidence of cancer in regular smokers is 3 to 5 times higher than that of the normal population.
3. People who are exposed to radiation for a long time <br/>Excessive radiation exposure inside and outside the body, especially mining workers who are exposed to asbestos, inorganic arsenic and other harmful substances for a long time without protection, have a high cancer rate.
4. Patients with chronic lung diseases <br/>Patients with chronic lung diseases such as emphysema and tuberculosis have a higher chance of developing cancer if they are not treated in time.
