What is Stereotactic Radiosurgery?

Stereotactic Radiosurgery, contrary to the way it sounds, is not an invasive surgery. It is a non-invasive procedure that uses high-powered x-rays or gamma rays in a very focused manner on a precisely defined portion of the body. This procedure has been used to treat brain disorders for several years but Stereotactic Radiosurgery in India is now finding application in treating medical conditions in other parts of the body such as the lung, liver abdomen, prostate, head and neck as well.


What medical conditions are treated by Stereotactic Radiosurgery in India?

Stereotactic Radiosurgery is being effectively used to for the treatment of several tumours in the brain and in the nervous system. A few examples:


When is Stereotactic Radiosurgery a better option?

Invasive surgery is not an option in those cases where the tumour or the target sites:

In the above situations, stereotactic radiosurgery in India is a good option to consider.


How is Stereotactic Radiosurgery done in India?

Stereotactic Radiosurgery comprises the following steps:

The delivery of radiation to the target site is typically done by using Linear Accelerator (LINAC) machines which are widely available at our associate hospitals in India. Some of our associate hospitals in Delhi, Mumbai, Bangalore, Chennai and Hyderabad also have the latest generation LINAC machines ( Novalis Tx, CyberKnife, etc). These machines deliver photons (x-rays at very high energy levels) to the tumour site in a very precise manner.

Radiation delivery is also done using the Gamma Knife which uses gamma rays instead of x-rays. The Gamma Knife surgery in India is considered to be more useful in the treatment of small tumours, while LINAC machines can handle large tumours as well.


How does Stereotactic Radiosurgery work?

Stereotactic Radiosurgery in India works by damaging the DNA of the tumour cells. Cancers are primarily caused by abnormal cells that multiply rapidly. Radiation, by damaging the DNA of the cells, neutralises their ability to multiply. Thus, over a period of time, the tumour size shrinks. Malignant tumours shrink fairly rapidly while benign tumours take a longer time, sometimes even a couple of years.


Who are the specialists involved in conducting Stereotactic Radiosurgery in India?

Treatment using Stereotactic Radiosurgery involves a team of specialists:


Does this procedure involve hospitalisation?

Hospitalisation is not essential. However for our foreign patients visiting India for treatment, it is more convenient to have the patient admitted to the hospital for two to three days, so that imaging and workup of the patient can be conducted rapidly and comfortably with the patient within the hospital.

Patients are normally able to resume normal activity within a day or two of the procedure.
