What is a bone scan?
A bone scan is an imaging test that can detect cancerous cells, evaluate fractures in the bones, and monitor other bone conditions, such as infections and arthritis. During a bone scan, a small dose of radioactive material is injected into a vein, where it travels through the bloodstream. The material collects in the bones and is detected by a scanner using nuclear imaging to reveal cell activity and function in the bones.
A bone scan can detect cancer that has metastasized to the bone from a different primary site, such as the breast, prostate or lungs. It may also be used to evaluate bone health before treatment.
