There are cured cases of stage III lung cancer, which are mainly related to the stage of disease, pathological type and treatment effect, and patient’s condition, and early standardized treatment is recommended. When lung cancer reaches stage III, that is, locally advanced stage, after standardized treatment, a small part of it may be cured, but most of it is difficult to be cured, and it needs to undergo combined treatment such as surgery, radiotherapy and chemotherapy, which can improve the prognosis and therapeutic effect. Stage III lung cancer often has lymph node metastasis and large lesions, so the possibility of cure is not high. Some of them are difficult to undergo radical surgical treatment, and some of them need to undergo chemotherapy and radiotherapy treatment to improve the prognosis. There are relatively few cases of stage III lung cancer being cured. If you feel unwell, it is recommended to go to the hospital in time to get a clear diagnosis and treatment so as to avoid delaying your condition.
