What are chondrosarcoma grades?

Chondrosarcomas are given a grade from 1 (I) to 3 (III). The lower the grade, the slower the cancer tends to grow and the less likely it is to spread:

• Low-grade (grade I) chondrosarcomas, also called atypical cartilaginous tumors, tend to grow the slowest and are very unlikely to spread.
• Intermediate-grade (grade II) chondrosarcomas are slightly more likely to spread.
• High-grade (grade III) chondrosarcomas are the most likely to spread.
