This year, in the United States, an estimated 800 to 900 people will be diagnosed with osteosarcoma, with about half being children and teens. About 2% of all childhood cancers are osteosarcoma. It is most often diagnosed between the ages of 10 and 30, with most diagnoses occurring in teens.
The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. However, the rate 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 overall 5-year survival rate for children and teens with osteosarcoma is 70%.
If osteosarcoma is diagnosed and treated before it has spread outside the area where it started, the general 5-year survival rate is between 60% to 75%. Osteosarcoma that has spread only to the lungs at the time of diagnosis has a 5-year survival rate of between 5% and 40%. If the cancer has spread somewhere else at the time of diagnosis, the 5-year survival rate is between 5% and 20%.
