Lung cancer is the cancer with the highest morbidity and lethality, and is the "most lethal tumor". Because there are no obvious symptoms and specificity in the early stage of lung cancer, many people find that it is in the middle and late stages. So, how terrifying is the late stage of lung cancer? The symptoms before the end of lung cancer are often more obvious, mainly including local advanced symptoms and extensive metastasis and spread symptoms. Common pre-mortem symptoms include hoarseness, chest pain, shortness of breath, fever, hemoptysis, etc., causing great pain to the patient. In general, the treatment of advanced lung cancer is mainly based on controlling symptoms to achieve the purpose of stabilizing the disease.

　　In recent years, lung cancer is no longer For the patents of the elderly, young people will also "stroke", even young people who do not smoke. Some people in the family of young people have had cancer. These young people have a special sensitivity to the stimulation of carcinogens, which creates conditions for the rejuvenation of cancer. The cell division and reproduction of young people are very vigorous and vulnerable to the attack of carcinogens. Although smoking history is a high risk factor for lung cancer, it does not mean that smoking will definitely cause lung cancer. In recent years, a large amount of chemical pollution and automobile exhaust emissions have caused serious air pollution and caused toxic substances to be inhaled by the human body. Infections such as EB virus and tuberculosis scars are also easy to ignore.

How long can patients with advanced lung cancer live?

Once diagnosed as "advanced lung cancer", many patients are caught in an infinite panic and feel that death is coming. According to statistics, in the treatment of lung cancer, only 15％ lung cancer patients can be treated by surgery to remove cancer cells, and about 5％ lung cancer patients cannot be operated due to tumor growth site restrictions, and more than 70％ ; Lung cancer patients can not be treated surgically because they did not find their condition in time. Taking lung cancer stage IV as a representative, if not treated in time, the survival period is about 3-6 months.

　　 In fact, it is not generalized how long patients with advanced lung cancer can live. Patients with advanced lung cancer can prolong survival if they are actively treated. Lung cancer is mainly divided into non-small cell lung cancer and small cell lung cancer. The probability of recurrence and metastasis of non-small cell lung cancer after surgery is also relatively high. The survival rates of patients with non-small cell lung cancer five years after surgery are respectively: stage I is 44.5％ stage II is 36.1％, Part III Stage A is less than 30％, the earlier the treatment of lung cancer, the higher the survival rate of patients.

　　 And for patients with early-stage small cell lung cancer, if surgical resection combined with biotherapy, radiotherapy and chemotherapy, in the absence of lung cancer lymphatic metastasis, the three-year survival rate can reach 65％ , The five-year survival rate can reach 50％. However, if there is already lymphatic metastasis of lung cancer, the survival rate of patients will decrease by 15-30 percentage points.

　　In general, the survival time of patients with advanced lung cancer mainly depends on three factors, one is whether the treatment is timely, the other is the malignant degree of the tumor, and the third is whether the treatment is appropriate. We look forward to the near future, with the development of medical technology, lung cancer treatment problems will be completely overcome.
