How long will the late stage of lung cancer fall asleep? Birth and death are natural laws. None of us can escape the disease, nor can we guarantee that we will not be sick for a lifetime. Lung cancer is a very high incidence of lung malignant tumors, which die of lung cancer every year The number of patients is countless. Once lung cancer develops into advanced stage, it will show many symptoms. So, how long will the lung cancer die from slumber?

　　Long-term slumber of lung cancer can last for how long? There is no accurate time limit for this problem. It varies from person to person. Because each patient''s physical condition is different and the treatment methods used are different, these will affect the final life span of patients with advanced lung cancer.

　　 The etiology of lung cancer is still not completely clear. A large number of data show that there is a very close relationship between long-term heavy smoking and the occurrence of lung cancer. Existing research has proved that the probability of long-term large smokers suffering from lung cancer is 10 to 20 times that of non-smokers. The younger the age of smoking, the higher the probability of lung cancer. In addition, smoking not only directly affects my physical health, but also adversely affects the health of the surrounding population, leading to a significant increase in the prevalence of lung cancer among passive smokers.

　　The clinical manifestations of lung cancer are more complicated. The presence, severity, and sooner or later of the symptoms and signs depend on the location of the tumor, the pathological type, the presence or absence of metastasis and complications, and the degree of patient response And tolerance difference. The early symptoms of lung cancer are often mild, even without any discomfort. The symptoms of central lung cancer appear early and severe, and the symptoms of peripheral lung cancer appear late and mild, or even asymptomatic. They are often found during physical examination.

　　 Chemotherapy is the main treatment method for lung cancer, and more than 90% of lung cancers need to be treated with chemotherapy. The effect of chemotherapy on small cell lung cancer is relatively positive in both early and late stages. There are even about 1% of early small cell lung cancer cured by chemotherapy. Chemotherapy is also the main method of treating non-small cell lung cancer, and the tumor remission rate of chemotherapy for non-small cell lung cancer is 40％～50％.

　　 Chemotherapy generally cannot cure non-small cell lung cancer, but can only prolong the survival of patients and improve the quality of life. Chemotherapy is divided into therapeutic chemotherapy and adjuvant chemotherapy. Chemotherapy requires different chemotherapeutic drugs and different chemotherapeutic schemes according to the histological type of lung cancer. In addition to killing tumor cells, chemotherapy also damages normal human cells, so chemotherapy needs to be performed under the guidance of a cancer specialist.
