Survival time of patients with advanced lung cancer varies from person to person and is related to the severity of the disease. If patients have brain metastasis, the survival period can be about six months; if patients have superior vena cava syndrome, the survival period can be only about three months. When lung cancer is detected, more than 80% of patients are in advanced stage, and the survival period needs to be determined based on the specific type, location and stage of lung cancer. According to clinical statistics, the probability of survival of patients with advanced lung cancer for 1 year is about 20%, and the 5-year survival rate is only 16%-17%. If patients have lymph node metastasis, but it does not affect eating, they can take radiotherapy, chemotherapy and targeted drug treatment under the guidance of doctors, together with functional exercise and should strengthen nutrition in daily life, so as to prolong the survival period, which can even reach 3-5 years. Patients in this category should strengthen outdoor exercise, prohibit smoking and drinking alcohol, reduce the intake of fatty and spicy stimulating food, eat more fresh vegetables and fruits, eat less and more meals, and have balanced nutrition.
