Key Statistics for Osteosarcoma

Osteosarcoma is not a common cancer. Each year, about 800 to 900 new cases of osteosarcoma are diagnosed in the United States. About half of these are in children and teens.

Most osteosarcomas occur in children and young adults between the ages of 10 and 30. Teens are the most commonly affected age group, but people of any age can develop osteosarcoma. About 10% of all osteosarcomas occur in people older than 60.

About 2% of childhood cancers are osteosarcomas, but they make up a much smaller percentage of adult cancers.

The prognosis (outlook) for people with osteosarcoma depends on many factors, including the location of the tumor, whether the cancer has spread (metastasized) when it’s first found, and the person’s age. Statistics related to survival are discussed in Survival Rates for Osteosarcoma.
