CyberKnife radiation surgery is the most advanced, non invasive radiation therapy tools available to treat especially non-cancerous as well as cancerous and other diseases with the help of precise beams of high-dose radiation. It is a no pain and a no risk day-care treatment wherein patients are discharged as soon as the session gets over and therefore, no hospitalization is required. The treatment uses a sophisticated image guidance system to beam high doses of radiation directly to your tumour. 

The CyberKnife radiation therapy has clinically proven success rates, however, it works the best for tumours that's upto 2-2.5 cm in size. However, in a few rare cases it is also used as an treatment option to cure brain tumours that either cannot be operated because of their location in the head, or the patients who cannot undergo brain cancer surgery due to their poor medical condition, etc.

The next generation of CyberKnife - M6 is highly precise when compared to the earlier ones used in India as this offers some of the exceptional features and delivers a maximum dose of radiation directly to the tumour from many different angles with sub-millimeter precision for the higher success rates. Also, the emitted focused beams of intense energy destroy cancer cells and shrink/control the growth of tumours. It further prevents the cancerous cells from multiplying. Infact, the objective of radiation therapy is to destroy the harmful cells while minimising damage to healthy cells.

Besides, the CyberKnife system automatically adjusts itself and tracks the tumour which aids in minimising radiation exposure to healthy organs and tissues. The CyberKnife radiation surgery offers multiple benefits compared to conventional radiation treatments and surgery.

In comparison to other traditional radiosurgeries like gamma knife, tomotherapy or conventional radiation therapy, M6 cyberknife robotic surgery eliminates the need for stereotactic head frames with screws and bolts thereby enabling the surgeon to achieve higher levels of micro-millimeter accuracy. The surgery is performed in a non-invasive manner with a higher brain surgery recovery time done on outpatient basis. The characteristics of M6 to pinpoint the exact location of the tumour in real time using 3-D imaging techniques during the treatment of brain tumour and ablating the tumour without any cut marks has proven outcomes to overtake the traditional methods of treatment. With the flexibility of the treatment to be done in 1 to 5 sessions each of 30 minutes duration provides comfortability to the patient and the maximum level of restricting the tumour from spreading further.

Conventional radiotherapies use small doses of radiation over weeks and months to treat tumours, and at the same time M6 cyberknife delivers high dose of radiation (100’s of narrow radiation beams) from different angles to intersect at the tumour. This helps in only ablating the tumour without damaging the surrounding sensitive brain tissues.

Till date M6 cyberknife is the most advanced and non-invasive radiation therapy available to treat the hardest to reach tumours (both tumourous and non-tumourous) with the help of a precise beam of high dose radiation. The treatment uses a sophisticated image guidance system to beam high doses of radiation directly to the tumour thereby eliminating the need for hospitalization. It is a no pain and a no risk day-care treatment wherein patients are discharged as soon as the session gets over.

This therapy has a proven clinical success rate of over 95% of the brain tumour patients and works best for tumours upto 2.5-3 cm in size. As the system automatically adjusts itself to track the tumour, it aids in curtailing the radiation exposure to healthy organs and tissues. The objective of the focused beam is only to destroy the harmful cells and prevent the tumourous cells from multiplying, provides multiple benefits over other radiosurgical treatments. The treatment through Cyberknife is cost effective and it is almost similar to the cost of other surgeries.
