The main causes of lung cancer

Among the many lung diseases, lung cancer is a more serious one. In fact, there are many causes of lung cancer in life, but people don't pay attention to them. Let's learn about them from the following article.

1. Smoking is one of the causes of lung cancer. Long-term smoking can lead to proliferation of bronchial mucosal epithelial cells, 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 the cause of lung cancer. Long-term exposure to radioactive substances such as uranium and radium and their derivatives, carcinogenic hydrocarbons, arsenic, chromium, nickel, copper, tin, iron, coal tar, asphalt, petroleum, asbestos, mustard gas and other substances can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.

4. Chronic lung diseases are also one of the causes of lung cancer if they are not treated. For example, tuberculosis, 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 metaplasia or hyperplasia during the healing process. On this basis, some cases may develop into cancer.

The above are all relatively effective causes of lung cancer. I hope everyone can understand as much as possible about the cause of lung cancer. If you have other questions about lung cancer, you can contact our online experts to answer your questions.
