1. Air pollution

(II) Human body internal factors

Such as family heredity, reduced immune function, metabolic activity and endocrine dysfunction.

3. Smoking

Long-term smoking can cause 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. Cigarettes release carcinogens when they burn.

4. Chronic lung diseases

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 lungs and bronchi and pulmonary fibrosis and scar lesions may cause squamous metaplasia or hyperplasia during the healing process. On this basis, some cases can develop into cancer.

5. Occupational factors

Long-term exposure to radioactive substances such as uranium and radium and their derivatives, carcinogenic hydrocarbons, arsenic, chromium, nickel, copper, tin, iron, coal tar, pitch, petroleum, asbestos, mustard gas and other substances can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.

After reading the five major causes of advanced lung cancer mentioned above, I believe everyone knows what advanced lung cancer is all about. For patients with advanced lung cancer, it is even more important to keep a cheerful and happy mood while following the doctor's treatment. Do more exercise in daily life, which also has a certain effect on the condition.
