CyberKnife Robotic Radiosurgery
CyberKnife Robotic Radiosurgery
For many cancers, CyberKnife® provides a precise, painless alternative to surgery or traditional radiation therapy.
El Camino Hospital’s cancer program offers the CyberKnife, an advanced form of radiation therapy that offers greater precision and fewer treatment sessions. CyberKnife, which was invented in Silicon Valley, allows us to eliminate solid tumors 90 percent of the time — without surgery.
At our Center for Advanced Radiotherapy and CyberKnife Radiosurgery on our Mountain View campus, we combine advanced expertise with compassionate, personalized care to support you throughout your treatment.
Our doctors have extensive experience using CyberKnife to treat noncancerous and cancerous tumors throughout the body, including:
- Brain and spinal tumors
- Head and neck cancer
- Kidney cancer
- Lung tumors
- Pancreatic cancer
- Prostate cancer
Painless, Noninvasive Targeted Therapy
Despite its name, CyberKnife radiosurgery doesn’t require any incisions, which is crucial for treating certain areas of your body, such as your brain and spine. CyberKnife greatly reduces the risk of damaging critical structures surrounding the tumor. The treatment is extremely safe in the hands of our experienced radiation oncologists.
CyberKnife's advanced capabilities allow us to pinpoint solid tumors anywhere in your body and deliver radiation with submillimeter accuracy. The improved accuracy means CyberKnife delivers a minimal dose of radiation to surrounding normal tissues. The enhanced precision allows us to delivery a higher dose of radiation to the tumor, so it requires fewer treatment sessions than traditional radiation approaches. For examples, traditional radiation therapy for prostate cancer requires multiple sessions over nine weeks, while CyberKnife therapy only requires four or five sessions.
Because CyberKnife doesn't involve surgery or anesthesia, you can have radiosurgery and go home the same day — without an overnight hospital stay. You can return to regular daily activities right away.
What to Expect During CyberKnife Treatment
Before beginning treatment, your doctor takes a high-resolution CT — sometimes along with an MRI or PET scan — to determine the size, shape and location of your tumor. Images are transferred digitally to the CyberKnife System, and one of our experienced clinicians matches the desired radiation dose to the tumor, while limiting radiation exposure to your surrounding healthy tissue.
In most instances, you remain in your street clothes as you lie on a treatment table. The CyberKnife robotic arm moves slowly around you to deliver radiation to the tumor from many different angles. A treatment session takes 30 to 90 minutes, depending on the type of cancer. If your treatment is being delivered in stages, you’ll return for additional treatments, up to five days.
There is little or no recovery time after each session, and you can return to regular activities right away. You may experience minimal side effects, such as fatigue or nausea, but those often go away within the first week or two.
Your care team will make sure you know what to expect during and after radiosurgery. We're here to answer your questions and make sure you have the support and information you need to feel comfortable.
