GammaKnife is a type of radiosurgery, that is, a surgery conducted with the help of radiation. It is a noninvasive treatment that helps destroy the cancerous tissue precisely from an identified location with the help of ionizing radiation. It can be used to treat cancerous as well as noncancerous tumors.
This type of radiosurgery does not require anesthesia. Most of such surgeries are performed in a single sitting. However, some candidates may require multiple sessions. It is decided using the planning phase before the administration of the treatment.
GammaKnife radiosurgery is not painful. The actual results of the treatment may be seen radiologically within a few weeks or months of first receiving radiation. For a few painful conditions such as trigeminal neuralgia, patients are relieved almost immediately and can lead a pain-free life. The effects in terms of pain relief can be seen within 1 day to a few weeks.
The following factors affect GammaKnife surgery cost:
The cost of GammaKnife radiosurgery is about $7000 to $9000 in India, $8500 to $11000 in Poland, $28000 to $38000 in the UK, $35000 to $45000 in the US, and $10000 to $13000 in Turkey.
People suffering from the following conditions are considered to be the perfect candidates for GammaKnife radiosurgery:
The tumors or lesions should be between 5 and 40 millimeters for it to be eligible for GammaKnife radiosurgery.

Gamma Knife surgery is a type of noninvasive procedure used to shrink or kill the tumor with the help of ionizing radiation. Unlike conventional surgery, Gamma Knife surgery does not include the use of scissors or surgical blades and knives to make an incision to access the tumor.
Gamma Knife is actually the name of the technique and the equipment that is used to deliver precise radiation to the tumor site. It allows for precise targeting of the tumor without affecting the nearby healthy cells and tissues.
It is a type of stereotactic radiosurgery (SRS) and similar to other techniques such as CyberKnife and X-Knife. Each type of SRS has its own benefits and limitations and therefore, the treatment is applied after careful selection of the candidates for each of these techniques available.
Gamma Knife radiosurgery uses specialized computerized treatment planning software that helps physicians locate the small target areas inside the head. These target areas are then irradiated with extremely high precision without damaging the nearby tissues.
This type of radiosurgery is now used for the treatment of a number of conditions, including primary or metastatic brain cancers, benign brain tumors (meningioma, acoustic neuroma, and pituitary adenomas), vessel malformations such as arteriovenous malformations, and functional disorders such as trigeminal malformations.
Gamma Knife radiation is used to treat brain lesions and inoperable tumors in the brains by targeting them with enough radiation. After the procedure, the targeted lesion is expected to shrink, disintegrate completely, or stop growing any further.
This type of radiosurgery is now used for the treatment of a number of conditions, including primary or metastatic brain cancers, benign brain tumors (meningioma, acoustic neuroma, and pituitary adenomas), vessel malformations such as arteriovenous malformations, and functional disorders such as trigeminal malformations.
Gamma Knife radiosurgery uses multiple beams of radiation to converge in three dimensions to focus on a small area of tumor or lesion precisely. This permits a large volume of high-dose radiation to be delivered with accuracy.
The Gamma Knife machine commonly being used worldwide uses robotic technology for submillimeter patient movement during the procedure to ensure that the complete targeted location is irradiated.
The following are the major steps that are executed during the procedure:
Depending on the requirement and treatment planning, a patient may need 1 to 5 sessions or sittings of Gamma Knife radiation to treat the lesion.
Gamma Knife radiosurgery is a painless procedure. Most of the patients nap during the procedure and so not feel anything.
The head may hurt for 10 minutes as the pins of the head frame are attached. But the pain subsides and there is not much sensation left because of the local anesthetic which is given.
The results and effects of the Gamma Knife radiation may start appearing anywhere from a day to a couple of weeks. The results of radiosurgery are visible on CT/MRI after a few weeks to a few months. However, there can be relief in pain in conditions such as trigeminal neuralgia almost immediately.
