Radiosurgery

What is radiosurgery?

Radiosurgery, also called stereotactic radiosurgery, is a very precise form of therapeutic radiology. Even though it is called surgery, radiosurgery does not involve actual surgery. Rather, very focused beams of radiation (gamma rays, X-rays, or protons) are used to treat cancerous tissues without a surgical incision or opening.

Radiosurgery is called "surgery" because it is a one-session radiation therapy treatment that creates a similar result as an actual surgical procedure.

How does radiosurgery work?

Radiosurgery works in the same manner as other types of therapeutic radiology: it distorts or destroys the DNA of tumor cells, causing them to be unable to reproduce and grow. The tumor will shrink in size over time. For blood vessel lesions such as an arteriovenous malformation (AVM), the blood vessels eventually close off after treatment.

What are the types of radiosurgery?

There are three types of radiosurgery. Each type uses different equipment and radiation sources. Radiosurgery types include:
