Benign tumors aren’t cancerous. While benign bone tumors typically stay in place and are unlikely to be fatal, they’re still abnormal cells and may require treatment. Benign tumors can grow and could compress your healthy bone tissue and cause future issues.
Malignant tumors are cancerous. Malignant bone tumors can cause cancer to spread throughout the body.
Primary tumors of bone can be divided into benign tumors and cancers. Common benign bone tumors may be neoplastic, developmental, traumatic, infectious, or inflammatory in etiology. Some benign tumors are not true neoplasms, but rather, represent hamartomas, namely the osteochondroma. The most common locations for many primary tumors, both benign and malignant include the distal femur and proximal tibia (around the knee joint). Examples of benign bone tumors include osteoma, osteoid osteoma, osteochondroma, osteoblastoma, enchondroma, giant cell tumor of bone and aneurysmal bone cyst
