Advantages of Gamma Knife

Gamma Knife Radiosurgery has many advantages compared with traditional surgery and other types of radiation treatment. Neurosurgeons and patients often prefer Gamma Knife Radiosurgery because:

  • It’s an outpatient procedure that takes less than a day
  • It doesn’t hurt
  • It doesn’t require incisions, so there’s no general anesthesia and no risk of bleeding or infection
  • It can treat even the most challenging, hard-to-reach brain tumours and abnormalities that traditional brain surgery can’t
  • Side effects, such as headaches and nausea, are rare and usually temporary
  • Patients can return to normal activities the next day


Gamma Knife radiosurgery is performed in hundreds of leading hospitals around the world with around 77,000 patients treated each year for conditions including brain tumours. With thousands of peer reviewed articles it has gained wide clinical acceptance. Results have proven to be superior or comparable to conventional neurosurgery or whole brain radiotherapy, depending on the specific condition treated.
