First of all, it should be noted that osteosarcoma can be detected in patients through imaging tests. For example, a localized MRI can clearly diagnose osteosarcoma. Once detected, it is necessary to actively pursue symptomatic treatment. Surgical removal is usually the main treatment method, involving the excision of the affected area. If necessary, the excision may need to be extended, or amputation may be required. After surgery, the excised specimen should be sent for pathological examination. Based on the results of the pathology test, further radiation therapy or chemotherapy can be completely sufficient. The results are generally quite good for most patients.
