Stereotactic Radiosurgery in India is a non-surgical radiation therapy used to treat functional disorders and small tumors of the brain. It can deliver precisely-targeted radiation in smaller high-dose treatments than standard therapy, allowing healthy tissue to be preserved. When SRS is used to treat body tumors, it’s called stereotactic body radiotherapy (SBRT). Outpatient procedures such as SRS and SBRT are common. Ask your doctor if you should arrange for someone to take you home afterward, and if you should wait several hours before eating, drinking, or taking any medications.

Stereotactic Radiosurgery in India is a non-surgical radiation therapy used to treat functional disorders and small tumors of the brain. It can deliver precisely-targeted radiation in smaller high-dose treatments than standard therapy, allowing healthy tissue to be preserved. When SRS is used to treat body tumors, it’s called stereotactic body radiotherapy (SBRT).
Outpatient procedures such as SRS and SBRT are common. Ask your doctor if you should arrange for someone to take you home afterward, and if you should wait several hours before eating, drinking, or taking any medications. Tell your doctor if you are pregnant, breastfeeding, or using oral or insulin to treat diabetes. Discuss whether you have an implanted medical device, claustrophobia, or allergies to contrast materials.
The cost of stereotactic radio surgery in India starts from 5500 USD. The patient must spend two days in the hospital and six days outside of it. The entire cost of treatment is determined by the patient’s diagnosis and the services he or she selected.
What Is Stereotactic Radiosurgery?
Stereotactic radiosurgery in India, or SRS, is a minimally invasive concentrated beam of radiation that aids in the destruction of cancer cells and other abnormalities of the brain, spine, and other body regions. The radiation beam is delivered using specialized equipment. Radiation is used with precision to ensure that adjacent organs and tissue are not harmed.
It is frequently used to treat disorders that do not originate in the central nervous system. There are several side effects that must be dealt with after radiation has successfully cured the disease. Fatigue, skin issues, and brain swelling are all common radiation after-effects. This is a targeted therapy that causes the cancerous cell to become distorted. There is no removal of the cancerous cell that is involved in the process.
Stereotactic body therapy in India, like stereotactic radiation, aims to cure cancer in the body. The radiation beams are specifically directed to the part of the tumor in this procedure. While the radiations are aimed towards the intended spot, the patient must remain in a static head position.
The specialized equipment focuses a large number of small radiation beams on a tumor or cancer growth. A single beam has minimal effects on the tissue it passes through, but at the point where all the beams connect, a focused dose of radiation is delivered. Tumors shrink and blood vessels block off over time as a result of the high dosage of radiation delivered to the affected area, shutting off the tumor’s blood supply.
How Stereotactic Radiosurgery Is used?
This treatment is only possible due to the development of cutting-edge radiation technologies that allow for maximum dose distribution within the target while limiting exposure to healthy tissue in the surrounding area. The goal is to deliver doses that will kill the tumor and give the patient permanent local control.
Several technologies are used in SRS and SBRT:
- Three-dimensional imaging and localization techniques that determine the exact coordinates of the target within the body
- Methods for immobilizing and positioning the patient with care, as well as maintaining the patient’s posture during therapy
- Gamma-ray or x-ray beams with a high degree of focus that converge on a tumor or abnormality
- Image-guided radiation therapy (IGRT) is a type of radiation therapy that employs medical imaging to confirm the location of a tumor before, and in certain cases, during, treatment. IGRT improves the treatment’s precision and accuracy.
CT, MRI, and PET/CT are three-dimensional imaging techniques that are used to find a tumor or abnormality within the body and characterize its exact size and structure. These images also help with treatment planning, which involves designing radiation beams to converge on the target area from various angles and planes, as well as patient positioning during therapy sessions.
Although SRS is most commonly associated with a one-day treatment, doctors may propose several stereotactically delivered treatments. This is important for tumors larger than one inch in diameter because the volume of normal tissue exposed to a single high dosage of radiation must be respected and limited, and the volume of normal tissue treated increases proportionally to tumor size. Radiation delivered in several sessions rather than one can improve safety and allow normal tissue to recover between treatments. As a result, fractionating the treatment allows for greater dosages to be provided while keeping an acceptable safety profile within the target. This approach is known as fractionated stereotactic radiotherapy (SRT), and it involves the administration of two to five doses of focused radiation, which are not always delivered on the same day.
SRS and SBRT are viable alternatives to invasive surgery, particularly for individuals who are unable to undergo surgery or who have tumors or abnormalities that are:
- Difficult to reach
- Located close to vital organs/anatomic regions
- Subject to movement within the body
Which Type of Disease Can Be Treated with Stereotactic Radiosurgery?
The following conditions can be treated with radiosurgery techniques:
Many types of Brain Tumors including:
- Benign and malignant
- Primary and metastatic
- Single and multiple
- Residual tumor cells following surgery
- Intracranial, orbital, and base-of-skull tumors
Arteriovenous malformations (AVMs) are tangled enlarged blood arteries in the brain that impairs normal blood flow and occasionally bleed.
Trigeminal neuralgia (a nerve problem in the face), tremors, and other neurological issues
SBRT is now used and/or being researched for the treatment of malignant and benign small-to-medium-sized tumors in the body and common disease sites, such as:
- Lung
- Liver
- Abdomen
- Spine
- Prostate
- Head and neck
Stereotactic radiosurgery in India works in much the same way as other types of radiation therapy. It does not remove the tumor; instead, it destroys the tumor cells’ DNA. As a result, these cells can no longer reproduce. Benign tumors normally diminish over the course of 18 months to two years after therapy. Tumors that are malignant or metastatic may decrease more quickly, even in a matter of months. Arteriovenous malformations (AVMs) treated with SRS may begin to thicken and shut off over a period of several years after therapy. Many tumors will remain stable and inactive for an extended period of time.
