Stage describes how far a cancer has spread.

Bone sarcomas can be staged using systems that consider tumor grade, and whether the cancer has extended beyond its original area, such as to your lungs. The staging system depends on where the bone cancer starts. For example, cancers in the arms, legs, trunk, skull or facial bones are staged differently from cancers in the pelvis or spine.

Staging tests

Tests used for staging assess a tumor's location and grade. Healthcare professionals look at how far higher grade chondrosarcomas have spread and whether these cancers have gone to the lungs. Your care team may check your lungs because aggressive chondrosarcomas often spread there.

Imaging of the primary tumor also helps determine its size and extent. These findings, together with the grade and information about distant spread, help your care team plan treatment.
