Malignant and Benign Tumors of the Bone

Tumors can form when cells divide and a mass of abnormal cells bind together. Typically, when this happens in the bone, the cause is unknown, but it can weaken the bone and cause pain or fractures. Most bone tumors are benign, or noncancerous, but some are malignant, meaning they are cancerous.

Types of benign bone tumors include:

• Osteoblastomas
• Osteoid osteoma

Types of malignant bone tumors include:

• Chondrosarcoma
• Chordoma
• Ewing's sarcoma
• Neuroblastoma
• Osteosarcoma

When the tumor starts in the bone, it is called a primary bone tumor. Secondary bone tumors are those that begin in another part of the body and spread, or metastasize, to the bone.

Bone Tumors Symptoms, Diagnosis and Outlook

Bone tumors are usually found after feeling a dull pain in the area of the tumor. Other symptoms include:

• Bone fractures
• Pain
• Weakness in arms or legs

To diagnose these types of tumors, the experts at Penn State Health may use several types of imaging technology, including X-ray, magnetic resonance imaging (MRI) or a computed tomography (CT) scan. Other tests include:

• Bloodwork
• Image guided biopsy may to analyze bone tissue
• Urine test

Your outlook will depend on the size and location of the tumor. Early diagnosis of a tumor is especially important if it is malignant. The earlier the cancer is found, you may have more treatment options available and clinical trials can expand your treatment options.
