Bone tumors are caused by an abnormal growth of cells. They may be benign (noncancerous) or malignant (cancerous). Although rare, bone tumors can occur in the foot and ankle. They can be primary (originating in the bone), or secondary (originating in another part of the body).

Symptoms of a bone tumor may include:
• Fracture from slight injury,
• Bone pain, often at night,
• Occasionally a mass or swelling in the area. 

A bone tumor is first diagnosed with x-rays. Advanced imaging modalities may be used to further evaluate the tumor. Surgical removal by a foot and ankle surgeon may be required for a definitive diagnosis.
