Stereotactic radio surgery (SRS) was developed over six decades ago and it has proved to be a successful technique of treating both malignant and benign lesions using anticancer drugs. Different machine configurations or treatment machines are used to treat patient with multiple brain metastases (mets or cancer cells that spread from the primary tumors in some body organs to the brain). The machines include the linear accelerator (linac), CyberKnife, and Gamma Knife which involve targeting several mets sequentially or individually.
