Advanced Radiation Therapy in St. Louis: Understanding the Benefits of the CyberKnife® System

July 1, 2026

Cancer treatment has advanced significantly in recent years, providing patients with more precise and less invasive options than ever before. For patients throughout the Greater St. Louis region, the CyberKnife® system offers an innovative approach to radiation therapy that can effectively target tumors while helping preserve surrounding healthy tissue.

At St. Louis CyberKnife, we utilize this advanced technology to provide personalized treatment plans designed around each patient’s unique diagnosis and needs.

A Different Approach to Radiation Therapy

The CyberKnife system is a robotic radiation delivery platform that uses advanced imaging and computer-guided technology to precisely target tumors throughout the body.

Unlike traditional surgery, the CyberKnife system treatments do not require incisions, anesthesia, or hospitalization. Instead, highly focused radiation beams are delivered directly to the treatment area with exceptional accuracy.

This approach allows clinicians to treat certain tumors and lesions while minimizing radiation exposure to nearby healthy organs and tissues.

Designed to Track Movement in Real Time

One of the most unique features of the CyberKnife machine is its ability to continually monitor and adjust for movement during treatment.

Because tumors can shift slightly due to normal breathing and other natural body movements, the CyberKnife system uses advanced image guidance to track the treatment target throughout each session.

This technology allows the system to:

  • Follow tumor movement during treatment
  • Adjust radiation delivery in real time
  • Maintain treatment accuracy throughout each session
  • Reduce unnecessary radiation exposure to healthy tissue

The result is a highly precise treatment experience designed to maximize effectiveness while minimizing side effects.

Conditions Commonly Treated with CyberKnife

The CyberKnife machine is used to treat a wide range of cancerous and non-cancerous conditions, including:

  • Prostate cancer
  • Lung cancer
  • Brain tumors
  • Spine tumors
  • Liver tumors
  • Pancreatic cancer
  • Metastatic tumors

Every patient receives an individualized evaluation to determine whether the CyberKnife treatment may be an appropriate option.

Why Patients Choose the CyberKnife Treatment

Many patients throughout Missouri and Southern Illinois are interested in treatment options that can fit into their lives while still delivering effective results.

Non-Surgical Treatment

The CyberKnife system treatments are completely non-invasive, eliminating the need for incisions and lengthy recovery periods.

Precise Tumor Targeting

The combination of robotics, imaging, and treatment planning software enables radiation to be delivered with extraordinary precision.

Shorter Treatment Courses

Depending on the diagnosis, many patients can complete treatment in just a few visits rather than several weeks of conventional radiation therapy.

Minimal Disruption to Daily Life

Most patients can return home immediately after treatment and continue many of their normal activities.

Customized Treatment Planning

Each treatment plan is tailored to the patient’s diagnosis, anatomy, and treatment goals.

What Patients Can Expect

The CyberKnife treatment process begins with consultation and imaging studies used to map the treatment area. Physicians then create a personalized treatment plan designed specifically for the patient’s condition.

During treatment, patients rest comfortably while the robotic system delivers radiation from multiple angles. Treatments are painless, and patients remain awake throughout the procedure.

Because there are no incisions or anesthesia, recovery time is minimal compared to many surgical approaches.
