Risk factors

Factors that can increase the risk of chondrosarcoma include:

• Increasing age. Chondrosarcoma occurs most often in middle-aged and older adults, though it can occur at any age.
• Other bone diseases. Ollier's disease and Maffucci's syndrome are conditions that cause noncancerous bone growths (enchondromas) in the body. These growths sometimes transform into chondrosarcoma.
