The survival time of advanced lung cancer depends on three factors: the specific pathological type of tumor, the patient’s own physical condition and the treatment taken. In advanced stage of lung cancer, there are usually metastases in other organs of the body, and the survival period is usually three months to one year. With the increase of tumor treatments and the common application of modern targeted drugs, the survival period of advanced lung cancer can be extended to two years or even longer. Lung cancer is divided into small cell lung cancer and non-small cell lung cancer. Small cell lung cancer progresses rapidly and is often found to have metastasized, which cannot be completely cured by surgery and has a poor prognosis. Advanced lung cancer is prone to complications such as lung infection, hemoptysis, pulmonary embolism, etc. If not treated in time, infectious shock and hemorrhagic shock can occur thus endangering life. If the patient has strong resistance and family members take good care of the patient, the chance of complications will be reduced and the survival period will be prolonged. Patients are advised to take oral Chinese medicine treatment, which can help to support the root, control the tumor progression and prolong the survival of patients.
