Facts and Statistics about Bone Cancer
  • Accounts for less than 1 percent of all cancers (only about 2,300 new cases each year in the US)
  • The most common types of bone cancer are Osteosarcoma, Chondrosarcoma, and the Ewing Sarcoma Family of Tumors.
  • Osteosarcoma occurs most commonly between the ages of 10 and 19. It is prevalent in the long bones of the arms and legs at areas of rapid growth around the knees and shoulders. It is a very aggressive cancer.
  • Chondrosarcoma occurs mainly in adults over age 40. It accounts for about a quarter of malignant bone tumors. These tumors arise from the cartilage cells. It most commonly affects the bones of the pelvis and hips. The five-year survival for the aggressive form is about 30%, but the survival rate for slow-growing tumors is 90%.
  • ESFTs occur most often in children and adolescents under 19. Boys are affected more than girls. It is the most aggressive bone tumor. It most commonly occurs in the middle of the long bones of the arms and legs. The three-year survival rate is about 65%.
Possible Causes
  • Previous radiation or chemotherapy
  • History of Paget's Disease, a chronic disorder that can result in enlarged and misshapen bonesexternal image Bone-Cancer-Treatment.jpg
  • Heredity
  • Metal Implants
Symptoms
  • A mass or lump felt either on the bone or in the tissues surrounding the bone
  • A fracture after little or no trauma
  • Pain, numbness, or tingling in the extremities
  • Fever, chills, night sweats, and weight loss
  • Unusual swelling
Diagnosis
  • X-rays- shows the location, size, and shape of a bone tumor
  • Bone scan- identifies areas of rapidly growing or remodeling bone
  • CT scan- gives good detail of your bones and is able to identify a possible tumor
  • MRI- provides better detail of the soft tissues, including muscles, tendons, ligaments, nerves, and blood vessels than a CT scan
  • A PET scan- uses radioactive glucose to find cancer cells in the body
  • Biopsy
  • Blood tests- determine the level of an enzyme called alkaline phosphatase

Treatment
  • Surgery
  • Chemotherapy
  • Radiation
  • Cryosurgery- use of liquid nitrogen to freeze and kill cancer cells
  • Follow up treatment, including frequent blood tests and checks by your doctor, is very important; people who have had bone cancer have an increased risk of getting leukemia later on in life
