What is the difference between osteocarcinoma and osteosarcoma?

Answer 1

A sarcoma is a cancer of the connective or supportive tissue (bone, cartilage, fat, muscle, blood vessels) and soft tissue. This is in contrast to carcinomas, which are of epithelial origin (breast, colon, pancreas, and others).

Answer 2

Sarcomas arise from mesenchymal cells, while carcinomas arise from epithelia cells. I believe osteocarcinomas are rare compared to osteosarcomas, but I do not know how this would affect the prognosis in the patient.
