ON THIS PAGE: You will find information about how many people, including children, are diagnosed with this type of cancer each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.
This year, an estimated 800 people total, including 400 people younger than 20, will be diagnosed with osteosarcoma in the United States. About 2% of all childhood cancers are osteosarcoma. It most often affects adolescents and young adults in their 20s.
The five-year survival rate is the percentage of people who survive at least five years after the cancer is found. It depends on the type and subtype of the cancer, the cancer’s response to treatment, and the degree to which the cancer has spread. The five-year survival rate for children with osteosarcoma is 71%.
Cancer survival statistics should be interpreted with caution. These estimates are based on data from thousands of people with this type of cancer in the United States, so the actual risk for a particular individual may be different. It is not possible to tell a person how long he or she will live with osteosarcoma. Because the survival statistics are measured in five-year intervals, they may not represent advances made in the treatment or diagnosis of this cancer. Learn more about understanding statistics .
