There are many types of malignant tumors, and they may grow in various parts of the body. Generally, except for the heart area, other internal organs or body surface and the head, malignant tumors may occur. Surgery is the first step. Malignant tumor is also a systemic disease that requires comprehensive treatment. After surgery, there is a possibility of recurrence, such as tumors that are not staged too early, even if surgery is done, there may be residual after surgery, or metastasis occurs early after surgery, which may lead to recurrence of lesions. Generally, clinical staging is made according to the pathological condition after surgery, and as long as the cancer is not very early or in situ, it needs to be treated with radiotherapy and chemotherapy after surgery. Sometimes, after recurrence, if the patient’s physical condition allows, surgery can be considered for radical treatment. In addition, there are other endocrine therapy, targeted drug therapy, and other comprehensive anti-tumor treatment methods.
