Where does bone cancer usually cause pain in its early stages?

The location of pain in early-stage bone cancer is not fixed and varies depending on the specific tumor location and the severity of the condition. Generally, the pain primarily occurs in the skeletal area affected by the lesion. For example, osteosarcoma commonly develops in the distal femur, proximal tibia, and proximal humerus metaphysis, and these areas may experience pain in the early stages. In addition, chondrosarcoma can cause pain in regions such as the pelvis, proximal femur, ribs, and proximal humerus. If unexplained bone pain occurs, especially persistent pain accompanied by swelling at the painful site or restricted joint movement, medical attention should be sought promptly for a comprehensive examination.
