There is no way to determine how long a person can live with advanced lung cancer treated with traditional Chinese medicine conservatively, but if the effect is good, the patient can live for 1-2 years, and if the effect is bad, the survival period is only about 3 months, which needs to be determined by combining various factors. Patients with advanced lung cancer have already had metastasis and spread of cancer cells in lymphatic system and distant tissues, and the treatment is mainly based on radiotherapy, chemotherapy and targeted therapy, etc. Traditional Chinese medicine treatment is mostly used as an auxiliary means, and the effect of simple medication is not very ideal, and the patients with good effect can stabilize their condition, with the survival period of about 1-2 years. However, in case of advanced lung cancer with high malignancy, the condition develops more rapidly and the above treatments are not very ideal, and the survival period is relatively shorter, which may be only 3 months, and in some cases, death may occur in a month or so. Lung cancer in advanced stage also needs active treatment, which can help prolong the survival period and improve the quality of life.
