Gamma Knife Radiosurgery: Side Effects, Risks and Recovery

Gamma Knife radiosurgery can be an excellent treatment option for many patients in the tri-state area. Whether you already have a procedure scheduled or are still exploring your treatment options, understanding more about your Gamma Knife treatment options will help set your mind at ease through the process.

What is Gamma Knife Radiosurgery?

Gamma Knife radiosurgery may sound like a surgical procedure, but it is actually an advanced form of radiation therapy available in northern NJ. During treatment, almost 200 individual beams of low-dose radiation are focused on the area of interest, with an accuracy of 0.15 mm. That’s the width of just one human hair. As a result, surrounding healthy tissues are spared. This means fewer unpleasant side effects than traditional radiation therapy and none of the risks of open surgery.

Conditions Treated with Gamma Knife Radiosurgery

Gamma Knife radiosurgery can be used to treat a variety of conditions, either as the primary treatment or following surgery. These include:
