Chondrosarcoma Risk Factors
Most often, chondrosarcoma occurs from normal cartilage cells, but it may also stem from a preexisting benign (non-cancerous) bone or cartilage tumor. The following is a list of some benign conditions that may be present when chondrosarcoma occurs:
- Enchondromas - A type of benign bone tumor that originates from cartilage and usually affects the hands (can also affect other areas).
- Osteochondromas - An overgrowth of cartilage and bone near the end of the bone near the growth plate.
- Multiple exostoses - The presence of multiple osteochondromas (an overgrowth of cartilage and bone near the end of the growth plate).
- Ollier's disease - A cluster of enchondromas (benign cartilage tumors that usually affect the hands).
- Maffucci's syndrome - A combination of multiple enchondroma (benign cartilage tumors that usually affect the hands) tumors and angiomas (benign tumors made up of blood vessels).
