ing bone metastases and delivers targeted high-dose radiation to cancer cells while minimizing exposure to healthy tissue. Treatment is delivered in one to five sessions and no overnight hospital stay is required. Recovery time with radiosurgery is much shorter than standard surgery, and treating more than one metastasis is typically easier with radiosurgery than conventional surgery. While healthy tissue can be damaged with conventional radiation therapy for bone metastases, radiosurgery with CyberKnife spares normal tissue, which is particularly important when treating spinal metastases close to a critical structure, such as the spinal cord. Radiosurgery has been shown to control tumor growth and provide pain relief.
