As a malignant tumor, lung cancer has great harm to the health of the human body, and the patients in the clinical stage are more painful, and the patient's physical condition is poor. So what will happen to the general patient?
1, bronchial obstruction by the tumor, the original normal alveolar cavity no longer exists;
2, if the development of lung cancer accounted for most of the lung, it will seriously affect the respiratory function of the lung;
Cancer bronchial irritation nerve 3, grow, will suffer severe dry cough, hemoptysis occurred sometimes;
4, if the spread of lung cancer to the chest can cause chest pain, chest water can also occur, the pressure of the lungs, can increase the difficulty of breathing;
5, if the lung cancer spread to the body, spread to the brain or liver is an important organ of the human body, can cause brain dysfunction and liver damage, important organs of human body is too large, it is difficult to maintain a normal life, even life-threatening. Advanced lung cancer, such as metastasis to the bone, can cause severe bone pain, and can be a pathological fracture. In addition, metabolites of metabolites in tumor and normal tissue is different, with a certain toxicity. Therefore, the tumor is too large, even if not to infringe other organs of the human body, can endanger life.
The cause of lung cancer is complex, which may be related to smoking, air pollution, long-term exposure to certain chemical carcinogens and radioactive substances. At the same time, it is difficult to detect lung cancer in early stage. At present, surgery and chemotherapy are the main methods for the treatment of patients with advanced lung cancer. One
