CyberKnife cures cancer without surgery or pain


For more than 30 years, traditional radiosurgery systems, or systems that deliver precise, high dose radiation directly to a tumor, have been used primarily to destroy brain tumors. The CyberKnife System represents the next generation of radiosurgery systems, combining continual image-guidance technology with a compact linear accelerator that has the ability to move in three dimensions according to the treatment plan. This combination, called intelligent robotics, extends the benefits of radiosurgery to the treatment of tumors anywhere in the body.

Traditional radiosurgery systems have limited mobility and generally require the use of rigid frames attached to a patient’s skull to provide a coordinate system to effectively target a tumor, restricting their ability to effectively treat tumors outside of the brain. The CyberKnife® System does not have these limitations and, therefore, has increased flexibility to treat tumors throughout the body from many different directions, while minimizing the delivery of radiation to healthy tissue and vital organs.

The CyberKnife procedure requires no anesthesia, can be performed on an outpatient basis and allows for the treatment of patients that otherwise would not have been treated with radiation or who may not have been good candidates for surgery. In addition, the CyberKnife procedure avoids many of the potential risks and complications that are associated with other treatment options and is more cost effective than traditional surgery.

The World Health organization (WHO) estimates that there are 24.6 million people living with cancer worldwide, with approximately 10.9 million new cases being diagnosed every year. To date, Accuray has brought the superior tumor treatment capabilities of the CyberKnife System to more than 50,000 patients around the world, including those with tumors previously considered inoperable or surgically complex.

Since the launch of the CyberKnife System, Accuray has undertaken an aggressive strategy to develop system enhancements that facilitate clinicians’ ability to treat tumors anywhere in the body with the highest levels of accuracy. Currently, Accuray has installed more than 150 CyberKnife Systems worldwide and a large body of peer-reviewed papers supports its clinical practice. Accuray is committed not only to continuing its tradition of advancing the field of robotic radiosurgery, but also to providing its customers with the highest level of support in their ongoing efforts to fight cancer.
