What Is Radiosurgery?

  • Stereotactic radiosurgery (SRS)
  • Concentrates radiation on the tumor or structure being treated
  • Limits the radiation delivered to normal tissue
  • Allows treatment close to critical structures because targeting is precise
  • Allows treatment of a lesion with a single radiation treatment or a small number of fractionated treatments, defined as hypofractionation
  • Allows treatment of some tumors that cannot be treated by radiotherapy
