Chronic lung disease is the sixth cause of lung cancer
When lung cancer has become one of the most dangerous diseases in mankind, many people talk about the discoloration of "cancer", people are flustered, and they naturally look for causes and preventive measures. In the existing etiological statistics of lung cancer, there are six major causes, the first is smoking, followed by environmental factors, air pollution, occupational factors, internal factors of the human body, chronic lung diseases and so on.
Most lung cancers are parasitic in the bronchial mucosal epithelium and become a kind of malignant dilatation in which the growth of cells in the lung tissue is out of control, and it can also metastasize or invade the adjacent tissues to form a new malignant dilation. In all lung cancers, the extremely acidic substances in cigarettes cause acidification and cause cancer to varying degrees. This is due to the strong carcinogenic activity of polychain aromatic hydrocarbons and nitrosamines in cigarettes.

Environmental factors are strong radioactive elements, such as Gejiu and Xuanwei in Yunnan Province, which are famous for the high incidence of cancer in the world, and there are carcinogens such as radon, tin, arsenic, toluene, etc., but the cancer rate in this area rises first; air pollution such as haze, industrial waste gas, traffic waste gas, there will be a large number of benzopyrene carcinogens, increasing the lung cancer rate.
Occupational factors refer to people's long-term exposure to radioactive substances and derivatives such as uranium and radium, carcinogenic hydrogen compounds, arsenic, coal tar, chromium, nickel, copper, tin, iron, petroleum, mustard gas, asphalt, asbestos, and so on, have become invisible carcinogens. There are people's eating habits after the change of physical acidification, immune function decline, leading to cell carcinogenesis.

Although cancer does not inherit cancer directly, it can inherit low-energy immune function, metabolic activity, and endocrine disorders, and this defense ability is reduced, giving cancer an opportunity to attack. Chronic diseases of the lungs, such as tuberculosis, silicosis, emphysema and chronic bronchitis, are easy to turn into cancer. It is widely known that there is no need to say much.
