Let's talk about the causes of lung cancer in detail. What factors are related to it?

The number of smokers is increasing, and they tend to be younger. Smoking is one of the causes of lung cancer. So what are the causes of lung cancer? Let our experts explain to you what are the causes of lung cancer.

What factors are related to the cause of lung cancer? The following is an introduction to what factors are related to the cause of lung cancer:

The cause of lung cancer is closely related to smoking. The increase in the incidence of lung cancer is parallel to the increase in cigarette sales. Cigarettes contain a variety of carcinogens such as benzopyrene. The incidence of lung cancer in smokers is 10 times higher than that of non-smokers, and the incidence is even higher for those who smoke a lot, 20 times higher than that of non-smokers. At the end of the 20th century, with the increasing number of female smokers in Western European countries, the incidence of lung cancer in female patients also increased significantly. Among clinically diagnosed lung cancer cases, more than 80% of them smoke more than 20 cigarettes a day for more than 30 years.

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.

What factors are related to the cause of lung cancer? I believe that after reading the above explanation, you will have a certain understanding of what factors are related to the cause of lung cancer!
