Press Release : Nov 17, 2009 – Manila, Philippines – – An experienced guide in medical tourism, understands your need in finding medical services that are affordable and excellent. For patients who suspect that they have a brain tumor and want it to be treated, Wellness and Health Services Asia Inc. (WAHSA) can help you search medical facilities that have gamma knife surgery.

The gamma knife, known to be used in treating brain tumors, has been proven to be safe because of the very small risk involved in gamma knife radio surgery treatment. The device uses a high dose of radiation therapy to treat the brain tumor. The gamma knife device contains a 201 cobalt-60 source that is placed in a circular array in a heavily shielded assembly. Each 201 cobalt-60 source contains approximately 30 curies. The device focuses the gamma radiation at a target point in the patient’s brain.

The patient wears a specialized helmet that is fixed to the patient’s skull through surgery. After the patient wears the helmet, multiple beams of gamma radiation is sent to the brain tumor in one treatment session. The gamma knife center uses computerized data from imaging tests like CT scans, MRI’s or arteriogram to pick the targeted area within the brain.

The gamma knife radio surgery treatment uses high doses of gamma radiation to kill cancer cells and shrink tumors. It is able to precisely focus multiple beams of high-intensity gamma radiation to the targeted area in order to avoid damaging healthy brain tissue. Each individual beam of gamma radiation has relatively low energy so it has no significant effect on intervening brain tissue. Only the targeted area is affected by the gamma radiation.

The procedure has been proven to be effective since more than 200,000 patients have already undergone the procedure worldwide. The procedure is non-invasive and it has negligible risk of infection or hemorrhage. Aside from treating brain tumors, the procedure has also been proven to be effective for treating vascular malfunctions such as arteriovenous malformation (AVM) and other functional problems.

Gamma knife radiosurgery for essential tremor: A Case report and review of the literature

Approximately 5 million people in America are affected by essential tremors (ET), which are classified as a type of benign movement disorder. This disease manifests as tremors that usually occur in the hands, but they may also be present in the head, face, tongue, and lower limbs.

Radiofrequency thalamotomy (RF) and deep brain stimulation (DBS) are common invasive procedures with proven track records that are used to treat ET. Although these procedures have high success rates, they still put patients at risk of potential side effects and are invasive by nature.

Thalamotomy using the gamma knife (GK) also produces favorable outcomes in treating tremors, without the complications associated with invasive neurosurgery procedures. This report describes the presenting symptoms and extended treatment outcome for a patient with an advanced case of ET, who received GK thalamotomy treatment six years ago.

Because of this non-invasive treatment, she regained the ability to paint and live with an improved quality of life. We also discuss and review the relevant literature regarding the risks and benefits of this treatment modality.

GK thalamotomy is one effective option for the treatment of ET, and due to its noninvasive nature, it has a different risk profile than neurosurgery. We suggest that GK thalamotomy should be presented as one viable treatment option to all ET patients, and should be recommended to those who would be best served by less invasive treatment techniques.

Gamma Knife treats brain tumors without surgery

IP News

ALBUQUERQUE, N.M.: Doctors scanned Roxanna Meyers' brain a year and a half ago and found the same type of tumor her mother had about 30 years before.

Meyers' mother had brain surgery to remove a much larger tumor, requiring a shaved head and a long stretch in the hospital.

"She's never been quite the same,'' says Meyers, president of Century Sign Builders in Albuquerque. ``It just really altered her personality.''

Meyers' tumor was treated on a Thursday in May. She left with a full head of hair and was back at work the following Monday.

The difference is the Gamma Knife, technology that delivers highly focused radiation to damaged brain tissue in a single day's outpatient treatment. The technology has been in the state for almost six years, offering what doctors call a remarkable treatment to more than 700 New Mexico residents, most with tumors.

For many years, says Dr. Andrew Metzger, a neurosurgeon and the state's Gamma Knife medical director, traditional surgery was the accepted way to treat many tumors.

These surgeries could be risky, and although neurosurgeons learned to improve the technique of removing difficult tumors, even through the base of the skull, Metzger says the patients ``didn't fare very well'' after the procedures and had weeks of recovery in store. Gamma Knife patients tend to be in and out in one day, usually a Thursday. They are told to take off work Friday and are generally able to return to normal the following week. Other non-surgical treatments, the most common form of which is full-brain radiation, have heavy costs.

Full-brain radiation can last weeks, with multiple exposures, Metzger says, and can cause hair loss, sunburns on the scalp and even cognitive problems. Gamma Knife patients typically have none of these.

Gamma Knife centers throughout the world treated almost 450,000 people at 257 sites between 1991 and 2007, according to a report from Elekta, the device's maker. Before 2003, when the only Gamma Knife center in New Mexico opened at Lovelace Medical Center in Albuquerque, patients had to travel to Arizona or Texas to receive the treatment.

"I like to think it's had a very positive impact on giving people options they didn't have before,'' Metzger says. ``It means being able to offer people a treatment that has some advantages over the alternative.''

Dr. Bob Hoppman, manager of the Gamma Knife Center New Mexico, says the machine has 201 cobalt-60 radiation sources that can be directed with extreme precision at targets inside the brain.

On the day of her procedure in late June, doctors gave Doni Carpenter, 78, four hefty shots of numbing medication, then screwed on pins for the boxlike metal frame used to keep her head immobile.

Carpenter then sat for a brain scan, which her doctors including Metzger used to plan her Gamma Knife treatment.

Gamma Knife Surgery: Preferred Destination India

Gamma Knife surgery is recognized worldwide as the preferred treatment for brain tumors, arteriovenous malformations and brain dysfunctions such as trigeminal neuralgia. It is supported by over 2,500 peer reviewed research articles that are primarily published in neurosurgery

journals. The Gamma Knife® offers a non-invasive alternative for many patients for whom traditional brain surgery is not an option. Gamma Knife® surgery removes the physical trauma and the majority of risks associated with conventional surgery. This effective single session treatment may require an overnight hospital stay, but is often done in an outpatient surgical setting with periodic follow-up. It has been proven safe over the long term and is recognized and covered by insurance plans.

The same as neurosurgery, the Gamma Knife® allows noninvasive cerebral surgery to be performed in one session and with extreme precision, sparing tissues adjacent to the target. Based on preoperative radiological examinations, such as CT scans, MR scans and angiography

, the unit provides highly accurate irradiation of deep-seated targets, using a multitude of collimated beams of ionizing radiation with scalpel-like precision.

Gamma Knife® surgery represents a major advance in brain surgery, and in the last three decades has changed the landscape within the field of neurosurgery. Its development has enhanced neurosurgical treatments offered to patients with brain tumors and vascular malformations by providing a safe, accurate and reliable treatment option. Gamma Knife® enables patients to undergo a non-invasive form of brain surgery without surgical risks, a long hospital stay or subsequent rehabilitation.

Like other radiosurgery, Gamma Knife® surgery is unique in that no surgical incision is made to expose the inside of the brain, thereby reducing the risk of surgical complications and eliminating the side effects and dangers of general anesthesia. The "blades" of the Gamma Knife® are the beams of gamma radiation programmed to target the lesion at the point where they intersect. In a single treatment session, 201 beams of gamma radiation focus precisely on the lesion. Over time, most lesions slowly decrease in size and dissolve. The exposure is brief and only the tissue being treated receives a significant radiation dose, while the surrounding tissue remains unharmed.


  • Gamma Knife® is a neurosurgical tool designed exclusively for the treatment of brain disorders.

  • The lesion being treated receives a high dose of radiation with minimum risk to nearby tissue and structures.

  • The cost of a Gamma Knife® procedure is often 25% to 30% less than traditional neurosurgery.

  • Patients experience little discomfort.

  • The absence of an incision eliminates the risk of hemorrhage and infection.

  • Hospitalization is short, typically an overnight stay or an outpatient surgical procedure. Patients can immediately resume their previous activities.

Gamma Knife® technology allows treatment of inoperable lesions. The procedure offers hope to patients who were formerly considered untreatable or at very high risk during open skull surgery.

India will soon become THE global health destination. It is replicating the Thai model, which has been the first Asian destination for International Patients. India benefits from a large staff of world class experts and the ultra-competitive cost advantage it offers. Metro cities in India like Mumbai, Delhi, Chennai and Hyderabad offer world class medical healthcare facilities to international patients who wish to have their gamma knife surgery in India.

With prices at a fraction of those in the US or EU, the concept has broad consumer appeal. Indian private facilities offer advanced technology and high-quality treatment at par with hospitals in western countries.

India is promoting "medical outsourcing" where subcontractors aim to provide services to the overburdened medical care systems in western countries. Medical tourism to India is growing by 20% a year. Most non-urgent Western patients usually get a package deal that includes flights, transfers, hotels, treatment and often a post-operative vacation. There are many brokers specialized on the Indian market. For more details on Gamma knife surgery in India visit and

Gamma Knife Surgery - from the patient's perspective

Trigeminal Neuralgia Gamma Knife Surgery

by James Dalton

Trigmenial Neuralgia is an incapacitating disease that can push persons to commit suicide due to the grave pain that they feel. To help relieve the pain various treatments are available. Gamma knife as a treatment for Trigmenial Neuralgia will be the highlight of this article. The article will aim to find out how successful the treatment is for this condition.

Being in the same field as neurosurgery; Gamma knife is a method of non-invasive surgery No incisions need to be made when going for treatment. One benefit of doing this kind of surgery is that it complications are reduced that usually occur when people do traditional surgery. Even though it is called a knife, the Gamma Knife is not one. It is a very complex machine that uses energy to focus gamma beams onto the affected sector of the brain. It is during the treatment 201 beams of gamma radiation are blasted into the brain. There are around 201 gamma beams that are used in the treatment. Only the affected region is affected by this treatment, surrounding tissues are not damaged.

For many decades, the Gamma knife has be used as an efficient treatment of Trigeminal Neuralgia. Great success has been had from this type of surgery, especially as technology has advanced. The first use of the Gamma Knife on Trigeminal Neuralgia was in 1951. The trigeminal ganglion is the main target of this radio surgery. The results over four decades were not highly successful. With the introduction of new technology such as high resolution imaging, the success rate increased. They were able to target the affected area much more easily.

Patients whousually have Gamma Knife surgery done on Trigmenial Neuralgia usually have andrastic reduction in their pain. Even though they experience relief, the effects are not immediately gone. This will decrease over the weeks. Studies have shown that people who have Gamma Knife Surgery done have experienced a significant reduction in the pain they feel. Reduction of pain for people who have the treatment is a high as 90%, with them experience pain relief a month after the surgery. The study that was conducted that numbness of the face was one of the side effects, that was experienced by 1/3 of the patients. That same study showed that patients included in that number showed considerable improvements despite the numbness they experienced.

The effective and safe treatment of the condition, trigeminal neuralgia, can be attributed to the use of Gamma Knife surgery. Complications with this type of surgery are minimized, as well as the success rate.

James Dalton has a vested interest in this product. He has a website dedicated to Gamma Knife on Trigeminal Neuralgia. Here you can find more detailed information on the product. He also has written on different topics that range from Trigeminal Neuralgia Surgery.
and Trigeminal Neuralgia.
