However, if the disease can be controlled through other treatments, it is possible to survive for a long time, for example, more than 3 or 5 years. There is no way to determine exactly how long you can live, you can only see it while you are undergoing treatment, because everyone’s condition is different, so you cannot use the survival time of one patient to describe the survival time of all patients with advanced lung cancer. There is a patient who had brain metastasis when the lung cancer was discovered, but survived for more than 5 years after targeted therapy and radiotherapy, and has survived for 8 years so far, which is a rather miraculous situation. Most of the intermediate and advanced stage patients who cannot be treated with targeted therapy, but only with chemotherapy or palliative radiotherapy, may survive within 3-5 years, but with targeted therapy, they may survive more than 5 years.
