Bone tumors, or bone tumors, are divided into benign bone tumors and malignant bone tumors, which are generally treated surgically, but the principles and methods of treating these two types of bone tumors are different. Benign bone tumors are generally more limited and have low recurrence rate after surgical resection in treatment, so the maximum limb preservation function should be strived for. For the tumor that protrudes outward to the bone, resection is adopted. For the tumor that grows inside the bone, the tumor tissue can be scraped off after cutting the bone wall until normal bone tissue is left, and at the same time, local filler can be placed to protect the limb function. Malignant bone tumor develops rapidly, and should be treated promptly once it is found. Surgery is the best treatment, but it should not be limited to the removal of the tumor, but should expand the scope of surgery and adopt amputation and joint severance. In addition, postoperative radiotherapy can help reduce the scope of surgery, preserve more limb functions and reduce the recurrence rate. Preoperative chemotherapy can reduce tumor volume and resection area, and postoperative chemotherapy can help improve tumor prognosis, reduce recurrence rate and improve patient’s survival quality. There are various treatment methods for bone tumors, and different treatment methods should be used under the guidance of professional bone oncologists.
