What Are the Key Statistics About Osteosarcoma?

Osteosarcoma is not a common cancer. Each year, about 1,000 new cases of osteosarcoma are diagnosed in the United States. About 450 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 osteosarcoma can occur in people of any age. About 10% of all osteosarcomas occur in people over the age of 60.

Osteosarcomas account for about 2% of childhood cancers, 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 the section What Are the Survival Rates for Osteosarcoma?
