What causes lung cancer?

Among the many cancer diseases, lung cancer is one of them. Knowing more about the causes of lung cancer will also help the treatment of lung cancer. Next, let's learn more about it in detail from the following article.

1. Smoking is one of the causes of lung cancer. Long-term smoking can lead to the proliferation of bronchial mucosal epithelial cells, which can induce squamous cell carcinoma or undifferentiated small cell carcinoma. Although non-smokers can also develop lung cancer, adenocarcinoma is more common.

2. The cause of lung cancer is air pollution, which seriously damages human health.

3. Occupational factors are also a cause of lung cancer. Long-term exposure to radioactive substances such as uranium and radium and their derivatives, carcinogenic hydrocarbons and other substances can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.

4. Chronic lung diseases can also cause lung cancer if they are not treated. For example, tuberculosis, silicosis, and pneumoconiosis 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 metaplasia or hyperplasia during the healing process. On this basis, some cases may develop into cancer.

The above descriptions are all about the causes of lung cancer. I hope everyone can understand how lung cancer occurs. If you have other questions about lung cancer, you can contact our online experts to answer your questions.
