Bone cancer refers to the abnormal growth of cells in the bones, leading to the formation of tumors. These tumors can be malignant or benign, with primary bone cancer originating in the bone itself and secondary bone cancer spreading from other parts of the body. Common types include osteosarcoma, Ewing sarcoma, and chondrosarcoma. Symptoms often include persistent bone pain, swelling, and fractures. Diagnosis involves imaging tests and biopsies. Treatment varies based on the type and stage, including surgery, chemotherapy, and radiation therapy. A multidisciplinary approach is crucial for managing bone cancer, focusing on both eradicating tumors and preserving the affected limb's function.
