Non-invasive radiosurgery
Clinical Acceptance
Because CyberKnife® is not yet available in some countries or is still new there, some doctors and medical charities are not yet familiar with it or have only have read earlier reports, issued as the system was being developed or first introduced.
Several centres have now installed a second CyberKnife to cope with rising demand.
Not just a single treatment

CyberKnife is a sophisticated operational tool, not a single treatment, so each procedure should be judged on its merits.  It was originally used for the brain and then for the spine before being approved for full body use and it can be used in many ways by highly skilled surgeons.  It is therefore well established for many treatments, whilst others are comparitively new and more are being developed in their own fields by specialist surgeons around the world.

Non-invasive medical technologies
Private medical centres
CyberKnife delivers multiple, precisely targeted doses of radiation from many different angles without the need for intrusive frames.
As treatments have extended to different organs of the body, new reviews may focus on these aspects, so perpetuating this idea.  In reality CyberKnife is now well established for a range of treatments whilst some others are still fairly new.

So how well established is CyberKnife?
The CyberKnife system is based on radiation technology that has been proven for 30 years and in 2001 it received FDA (the US medical regulatory body) clearance for treatment of tumours anywhere in the body where radiation was indicated.
Many clinical studies have been published in medical journals, over 90,000 patients have received treatment and there are now over 200 CyberKnife systems installed worldwide.
Several centres have now installed a second CyberKnife to cope with rising demand.
As CyberKnife becomes more widely available it sometimes forms just part of a wider treatment for difficult and complex cases.  For example pancreatic cancer is frequently well advanced by the time it is diagnosed and is liable to recur in other areas, no matter how successful initial treatment has been and by what means. 

Realistic expectations
CyberKnife is the only practical treatment option for some patients, whilst for others it will not be suitable.  For some it may be the only treatment they need whilst others may benefit from CyberKnife in combination with different treatments, depending upon their condition.  
Media reports and private internet 'blogs' sometimes overstate or oversimplify the benefits of CyberKnife radiosurgery.  It is nonetheless a valuable resource and extends the range of options available to specialists.  Even where it cannot provide complete treatment it may extend a patient's life and improve the quality of that life.
