ON THIS PAGE: You will learn about how doctors describe a cancer’s growth or spread. This is called the stage. To see other pages, use the menu.
Staging is a way of describing where the tumor is located, if or where it has spread, and whether it is affecting other parts of the body.
Doctors use diagnostic tests to find out the tumor's stage, so staging may not be complete until all of the tests are finished. Knowing the stage helps the doctor to decide what kind of treatment is best and can help predict a patient's prognosis, which is the chance of recovery. There are different stage descriptions for different tumors.
Doctors use following terms to describe the stage of osteosarcoma and to decide on the treatment plan:
Localized. The tumor is only in the bone where it began and in the tissue around it. The tumor has not spread to other parts of the body.
Metastatic. The tumor has spread from the bone where it began to another part of the body. Most often, it has spread to the lungs or other bones.
Recurrent. Recurrent osteosarcoma is a tumor that has come back during or after treatment. It can come back in the same place where it started or in another part of the body. Osteosarcoma recurs most often in the lungs and other bones. If there is a recurrence, the cancer may need to be staged again. This is called re-staging.
