Primary bone cancers are rare cancers that start in the bone. There are different types of bone cancer. Chondrosarcoma is one of the more common types.
Chondrosarcoma is a cancer of the cartilage cells. Cartilage is a tough, flexible material that covers the ends of the bones and allows them to move freely at the joints. Chondrosarcoma usually grows in a bone or on its surface. This type of cancer can occur at any age but is more common in people over the age of 40. It is slightly more common in men.
Chondrosarcoma is usually a slow-growing tumour. The most common sites affected are the:
- upper arms (humerus)
- thighs (femur)
- shoulder blades (scapula)
There are several sub-types of chondrosarcoma, including de-differentiated, clear cell and mesenchymal. These different types can be treated differently.
