Chondrosarcoma starts in cartilage, which provides protection to the ends of bones and joints, the National Cancer Institute explains. Although it is a common bone cancer, it is not easy to diagnose, the American Academy of Orthopaedic Surgeons notes. In its early stages, chondrosarcoma resembles noncancerous bone tumors. Therefore, imaging such as radiography or CT scans are needed for diagnosis. Chondrosarcoma typically does not respond well to chemotherapy or radiation therapy, so treatment usually involves surgery to remove cancerous tissue.

Ewing's sarcoma occurs both in hard and soft tissue, reports the National Cancer Institute. Most patients with the disease are teenagers or young adults. Tests used to diagnose Ewing's sarcoma include MRIs, CT scans, PET scans, bone scans, X-rays, blood counts and biopsies. Treatment usually involves chemotherapy to shrink tumors or halt their spread. External radiation therapy is sometimes used for the same purposes.

Any diseased tissue that remains after these therapies is removed surgically, notes the National Cancer Institute. Follow-up chemo or radiation treatments are sometimes needed if any part of the tumor remains.
