How CyberKnife® Works

What Is CyberKnife® Surgery Used For?

CyberKnife Robotic Radiosurgery treatment at NYU Winthrop Hospital on Long Island, NY gives new hope to thousands of people with tumors and lesions, may of which were once considered inoperable. This non-invasive alternative to surgery is used for the treatment of both cancerous and non-cancerous tumors anywhere in the body.

CyberKnife radiosurgery takes treatment of benign and malignant masses to a whole new level. CyberKnife delivers precise beams of high-dose radiation with extreme accuracy to tumors in the prostate, lung, brain, spine, liver, pancreas and kidney. Learn more about conditions CyberKnife treats.

NYU Winthrop Hospital’s CyberKnife Center is a worldwide leader among medical institutions offering breakthrough CyberKnife treatment. In addition to being one of the busiest and most experienced CyberKnife centers in the U.S., NYU Winthrop experts have trained physicians from around the world in the use of CyberKnife technology.

What is CyberKnife?

Despite the name, CyberKnife radiosurgery is actually not surgery. This non-invasive radiation therapy is painless and bloodless, and uses high-tech, cruise-missile-guidance technology and ultra-flexible, computer-controlled robotics to deliver precisely targeted radiation to tumors.

Dr. Jonathan Haas, Chairman, Department of Radiation Oncology at NYU Winthrop Hospital, oversees various forms of radiation treatments for a myriad of cancers. He considers CyberKnife radiosurgery as “the most advanced form of radiation therapy currently available, and one of the biggest advancements in cancer treatment in the last decade.”

CyberKnife Pioneers in Prostate Cancer Treatment

What is CyberKnife? CyberKnife radiosurgery is extraordinarily accurate. The radiation beams can be targeted to reach small, deeply imbedded, complex masses, while minimizing damage to surrounding healthy tissue. This remarkable capability provides unparalleled access to previously unreachable and untreatable tumors throughout the body. Moreover, it virtually eliminates most of the side effects commonly associated with other forms of radiation.

NYU Winthrop Hospital is a pioneer in the use of CyberKnife as a highly effective treatment for prostate cancer. With over 5 years of published clinical data, including the Stanford University Hospital study, it is clear that the success rate for CyberKnife matches or exceeds that of any other standard treatment option.

What Is CyberKnife Surgery like as an Outpatient Procedure?

An alternative to conventional surgery in certain cases, CyberKnife has transformed radiosurgeries of the brain, spine and soft-tissue into painless outpatient procedures that allow patients to resume normal activities soon after the procedure.

CyberKnife treatment takes up to five 45-minute sessions, unlike other radiation treatments which require longer sessions and a higher number of treatments over a period of many weeks.

After a CyberKnife treatment, patients are free to go about their daily routines with no interruptions. This is why CyberKnife is truly one of the most revolutionary forms of cancer treatment, and NYU Winthrop Hospital is proud to be a world leader in its use.
