A bone sarcoma is a primary malignant bone tumour, a type of sarcoma that starts in the bones.[1] This is in contrast to most bone cancers that are secondary having developed as a metastasis from another cancer. Bone sarcomas are rare, and mostly affect the legs. The other type of sarcoma is a soft-tissue sarcoma.
There are three main types of bone sarcoma based on tissue type – an osteosarcoma, a Ewing's sarcoma, and a chondrosarcoma.[1]
