What are the specific causes of lung cancer? Several common factors that lead to lung cancer

The cause of lung cancer is something we must understand. Some people don't know where to start treatment, that is, they don't have a clear understanding of the cause of lung cancer. Only by understanding the cause can we curb it fundamentally. Let me tell you what the causes of lung cancer are. Lung cancer is a ruthless disease that takes tens of thousands of lives every year. It is still rampant and rampant around the world. After years of clinical medical observation, medical scientists have gradually mastered the law of disease onset, and can better diagnose "lung cancer" to explore its ins and outs. Therefore, it has played an important role in the cure of lung cancer to a certain extent. What are the pathogenic factors of lung cancer? This problem that has troubled people for many years has finally been solved. After a lot of medical research, it has been shown that the pathogenic factors of lung cancer are inseparable from the following points. Smoking is the main factor causing lung cancer and a common factor: smoking is also one of the causes of lung cancer. Long-term smoking can cause bronchial mucosal epithelial cell hyperplasia, squamous cell carcinoma or undifferentiated small cell carcinoma. Although non-smokers can also suffer from lung cancer, adenocarcinoma is more common. Chronic lung disease is also one of the reasons: patients tend to ignore it at the beginning and often buy some painkillers. This is not good. It is not conducive to the stability of the condition and often aggravates the condition to a certain extent. 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. Pollution by radioactive elements is also one of the factors of its occurrence: 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.
