If a nodule is found in the body, the exact treatment must be determined by the location, nature and severity of the nodule. If benign nodules are considered, in most cases the decision on how to treat them is based on whether there are significant clinical symptoms. If there are obvious symptoms of pressure, it is recommended to consider surgical removal. If there are no obvious symptoms of benign nodules, regular observation is sufficient. If the nodule is malignant, it is usually a malignant tumor, and it is also necessary to improve the relevant examination to clarify the stage of the tumor before giving treatment. If it is an early stage tumor, radical surgery is needed to remove it. In case of middle and late stage, a comprehensive treatment based on chemotherapy, targeted therapy, immunotherapy, endocrine therapy, etc. is needed, and the main purpose is to prolong the survival time of patients.
