Gamma Knife Radiosurgery

What is Gamma Knife Radiosurgery?

It is a form of radiation therapy that uses hundreds of individual laser beams to target a tumour. Also, it acts as an alternative therapy to chemotherapy, surgery, or other forms of radiation oncology.

The treatment lasts around 15 minutes to over an hour depending on the condition of the patient. Patients might not have to undergo surgery where usually only sedation or local anesthesia is used for Gamma Knife Radiosurgery. This reduces their risk of infection and bleeding.

Usually patients will not feel any pain, possibly only a bit of discomfort from the local anesthesia and if there is a headframe that is fitted onto patients to prevent any head movements.

Why do you need Gamma Knife Radiosurgery?
