What is lung cancer? Here is an introduction to what lung cancer is:

Lung cancer occurs in the bronchial mucosal epithelium and is also called bronchial cancer. In the past 50 years, many countries have reported a significant increase in the incidence of lung cancer, and lung cancer has ranked first among male cancer patients.

The cause of lung cancer is still not completely clear. A lot of data show that long-term and heavy smoking is an important pathogenic factor of lung cancer. For those who smoke more than 40 cigarettes a day for many years, the incidence of squamous cell carcinoma and undifferentiated lung cancer is 4 to 10 times higher than that of non-smokers. The incidence of lung cancer in urban residents is higher than that in rural areas, which may be related to air pollution and carcinogens contained in smoke. Therefore, non-smoking should be advocated, and urban environmental sanitation work should be strengthened. Chronic lung diseases, such as tuberculosis, silicosis (silicosis), pneumoconiosis, etc., can coexist with lung cancer. The incidence of cancer in these cases is higher than that of normal people. In addition, chronic inflammation of the lung bronchi and pulmonary fibrosis scar lesions may cause squamous epithelial metaplasia or hyperplasia during the healing process. On this basis, some cases may develop into cancer.
