Radiation therapy

Radiation Therapy is the treatment of cancer with radiation. This can be done in a variety of ways, depending on the nature of your cancer.

The most commonly used method is called external beam therapy (from a machine outside the body), which directs radiation at your tumor.

Gamma Knife treatment

If you've been diagnosed with a brain disorder or metastases, you may be a candidate for Gamma Knife radiosurgery. Although it's called Gamma Knife, there is no blade or blood. Instead, it's a radiosurgical treatment that delivers a dose of gamma radiation to the target with surgical precision and is the most accepted and widely used radiosurgery treatment in the world.

On the following page, you can view videos of real patient stories and how Gamma Knife radiosurgery works. There are also links to help you find a Gamma Knife center near you along with detailed information on the treatment process.

Gamma Knife treatment


Brachytherapy is a type of radiotherapy that can be used to treat many types of cancer.

It is sometimes known as 'internal radiotherapy', or when used in the treatment of prostate cancer, 'seed therapy'.

Radiotherapy is an important method of treating cancer. It works by destroying cancer cells by targeting them with radiation and stopping them dividing and growing.

About 4 out of 10 people with cancer have some type of radiotherapy as part of their treatment.
