What are the causes and pathologies of lung tumors?

The incidence and mortality of lung cancer are rising rapidly, and smoking and the six chemicals are the main causes of lung cancer. A large part of the causes of lung cancer are caused by smoking or secondhand smoke.

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 tumors, mainly squamous cell tumors and undifferentiated small cell tumors. Occupational factors are an important part of the etiology of lung tumors. Chronic lung diseases, such as tuberculosis, silicosis, and pneumoconiosis, are also causes of lung tumors. Smoking: long-term smoking can cause bronchial mucosal epithelial cell hyperplasia, squamous cell tumors or undifferentiated small cell tumors. Although non-smokers can also suffer from lung tumors, adenocarcinomas are more common. When cigarettes burn, they release tumorigenic substances, which eventually lead to the cause of lung tumors.

Air pollution, with the progress of society, the industrialization of some regions is accelerating, so the atmospheric environment we live in is gradually damaged and polluted. The polluted air is inhaled into the lungs, causing the cause of lung tumors, thus greatly increasing the incidence of lung tumors. Internal factors of the human body, such as family inheritance, reduced immune function, metabolic activity, and endocrine dysfunction, are also causes of lung tumors.

Lung cancer is the most common primary malignant tumor of the lung. The incidence of lung cancer in young and middle-aged people is on the rise in my country, especially with the increase in female smokers. Especially in the future, the incidence of lung cancer in women is a very serious problem. It ranks second or third among the common malignant tumors in women.

Understanding the causes of lung cancer can help you prevent it. The causes of lung cancer are not yet fully understood, but a large number of experiments have shown that smoking, halogenated olefins, polycyclic aromatic compounds, nickel, etc. are risk factors for the lungs.
