Key Statistics for Osteosarcoma
Osteosarcoma is not a common cancer. Each year, about 1,000 new cases of osteosarcoma are diagnosed in the United States. About half of these are in children and teens.
Most osteosarcomas occur in children, teens, 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 1 in 10 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 where the tumor is, if the cancer has already spread (metastasized) when it’s first found, and the person’s age. For more on this, see Survival Rates for Osteosarcoma.
