Most patients are not aware of the difference between a bone tumor (a tumor that grows on top of the bone) doctor and a general orthopedic surgeon. When a bone tumor or damage to the bone is found, they often go back to a large hospital to see an orthopedic surgeon. This is a consultation strategy that has some errors. Orthopedic oncologists are orthopedic surgeons who have been orthopedic surgeons for more than 10-15 years and are familiar with orthopedic joints, spine, injuries, foot and ankle, etc., and have perfect training, and then further study and practice in the specialty of orthopedic oncology. The requirements of orthopaedic oncologists are the most demanding among all orthopaedic surgeons. The main reason for this is that orthopedic oncologists must have knowledge and practice in almost all orthopedic specialties and be very familiar with the management of various orthopedic diseases before they are qualified to start in the specialty of orthopedic oncology. The complexity of bone tumor not only lies in the extreme difficulty of surgery, but also in the fact that the diseases diagnosed are rare or complex, which requires a great deal of experience in clinical thinking and clinical decision making. In addition, high-end bone oncologists are qualified in basically all other specialties of orthopedics (such as joint, spine, injury, foot and ankle, etc.). And bone oncologists and doctors must also have knowledge of other tumors or cancers. So general orthopedic surgeon is one of the first processes that a bone oncology specialist must train for, and not any general orthopedic surgeon is qualified to become a bone oncologist. It is estimated that there are roughly 500 specialists with advanced expertise in bone tumor doctors nationwide, which shows the height and difficulty of bone tumor specialty.
