There is no inevitable relationship between the appearance of pain and the survival time of lung cancer, and the survival time may vary from several months to several years according to the different stages. 1. Early stage patients: some stage II non-small cell lung cancer that invades the chest wall but has no regional lymph node metastasis or distant metastasis may have pain at an early stage, and after active and standardized treatment, patients may have a 5-year survival rate of about 55%. 2. Advanced patients: pain is also often seen in advanced lung cancer patients, and advanced patients often have limited treatment means and effects. The 5-year survival rate of stage IV NSCLC is only about 5%, and patients who are not sensitive to treatment effects may only survive for several months. The type of pathology also affects the survival time of patients, for example, the 5-year survival rate of small cell lung cancer of the same stage is much lower than that of non-small cell lung cancer, so there are many factors affecting the survival time of patients, and it is not possible to judge how long they can live purely by the symptoms of pain. It is suggested that patients should take active treatment under the guidance of doctors to avoid delaying their condition.
