Chondrosarcoma
Chondrosarcoma is another type of
bone cancer that develops in the cartilage. Chondrosarcoma is commonly diagnosed in people between the ages of 50 and 60. Common areas where this type of bone cancer appears include the:
- Pelvis
- Upper legs
- Shoulders.
Ewing's Sarcoma
Evidence suggests that Ewing's sarcoma, another form of bone cancer, begins in the immature nerve tissue in the bone marrow. Ewing's sarcoma is usually diagnosed in people between the ages of 10 and 20. Common areas where this type of bone cancer appears include the:
- Pelvis
- Upper legs
- Ribs
- Arms.

Types of Bone Cancer: Metastatic Bone Cancer
When cancer spreads (metastasizes) from its original place to another part of the body, the new tumor will have the same kind of abnormal cells and the same name as the primary tumor. For example, if bone cancer spreads to the lungs, the cancer cells in the lungs are bone cancer cells. The disease is metastatic bone cancer, not
lung cancer, and it is treated as bone cancer, not as lung cancer. Doctors may call the new tumor "distant" disease.
Secondary Types of Bone Cancer
Bone cancer that appears in the bone (primary bone cancer) is different from cancer that spreads (metastasizes) to the bone from another part of the body (secondary bone cancer). Secondary bone cancer is much more common than primary bone cancer. Common types of secondary bone cancer include:
Primary bone cancer is rare. In the United States, approximately 2,500 new cases are diagnosed each year.
