Osteosarcoma is a tumor that grows in bones. This disease is more common in young people, usually under the age of 24. Most patients are not diagnosed until the middle or late stages of the disease. So how can we detect early osteosarcoma? Let's talk about this topic today. The early symptoms of osteosarcoma are not easy to detect. Patients should go to the hospital for examination in time when they feel unwell. The examination items include the following: 1. X-ray film: The X-ray manifestation of typical osteosarcoma is that the bone tissue has the characteristics of new bone formation and bone destruction at the same time. The tumor is mostly located at the metaphysis of the long tubular bone, with unclear edges, destroyed trabeculae, and increased density of tumor tissue. After penetrating the cortical bone, the tumor lifts the periosteum, producing the characteristic X-ray sign of the disease - Codman's cuff triangle (Codman-triangle). This phenomenon can be seen in some patients with osteomyelitis and Ewing's sarcoma, and is very typical in osteosarcoma. In the late stage, the shadow of tumor infiltration of soft tissue can be seen, and pathological fractures can be seen in some cases. 2. CT scan and MRI examination are effective means to determine the nature, extent and presence of surrounding soft tissue infiltration of bone tumors. They can detect metastatic lesions to the lungs and other organs at an early stage and are routine items in the clinical examination of osteosarcoma. 3. Radionuclide bone scanning is a commonly used method for early detection and late identification of the presence or absence of metastatic lesions. The above methods are the examination methods for the early onset of osteosarcoma. The last one is the most suitable for early osteosarcoma examination. These methods should be prescribed according to the patient's situation after the doctor's examination, so the patient only needs to follow the doctor's examination plan to do the examination. |
