Bone cancer

Cancer that originates in the bone — primary bone cancer — is rare. The condition affects more children than adults. More often, cancer cells spread (metastasize) to the bones from other areas of cancer in your body.
The most common forms of primary bone cancer are:
Osteosarcoma, which occurs primarily in growing bone tissue
Chondrosarcoma, which occurs in cartilage
Ewing's sarcoma, which arises primarily in immature tissue in bone marrow
Osteosarcoma and Ewing's sarcoma occur most often in children, adolescents and young adults, ages 10 to 25. Chondrosarcoma is more common in adults.
Treatment of bone cancer depends on the type of bone cancer, as well as its location, size and stage.

Signs and symptoms

Pain is the most common symptom of bone cancer. Although bone cancer can arise in any of your body's 206 bones, it most frequently occurs in the long bones of your arms and legs.
Other possible signs and symptoms of bone cancer include:
1. Weakened bones, sometimes leading to fractures
2. Joint swelling and tenderness (for tumors in or near joints)
3. Fatigue
4. Fever
5. Weight loss
6. Anemia
