What is the difference between primary bone cancer and metastatic bone cancer?
• A: Bone cancer is a malignant or abnormal, out-of-control growth found in any part of the bone, and in any bone of the body. Primary bone cancer occurs when the cancer originates in the bone itself. More commonly, metastatic bone cancer results when cancer spreads from somewhere else in the body to the bones. We refer to cancer that has spread as metastasized, and bone tumors from metastasized cancer as bone metastases. Primary bone cancers occur more frequently in children and young adults, particularly in those who have had radiation or chemotherapy treatments for other conditions.
