Bone Cancers and other Skeletal Tumors
Malignant Bone Tumors
- Primary Bone Cancers: These are malignant tumors (cancers) that arise in the bone and include osteosarcoma, and Ewing’s sarcoma. Primary bone cancers are more common in children.
- Metastatic Bone Cancers: Malignant tumors that arise outside the bones but travel to and implant within the bones. The most common metastatic bone cancers to affect the skeleton are lung cancer, kidney (renal) cancer, breast cancer, thyroid cancer, and prostate cancer. Metastatic bone cancers are more common in adults.
Benign Bone Tumors
These are tumors that arise within the bone and do not normally metastasize. The most common benign bone tumors are:
- Aneurysmal bone cyst
- Giant cell tumor
- Non-ossifying fibroma
These are bone abnormalities that are mistaken for tumors. These lesions usually do not require treatment.
