Stereotactic Radiosurgery (SRS) has transformed cancer treatment globally. According to recent statistics, more than 150,000 patients undergo this procedure annually worldwide, with success rates exceeding 85% for certain brain tumors. This level of precision offers hope for patients who once had limited or high-risk treatment options. In India, Dr. Mathangi, Senior Consultant & In-charge of Radiation Oncology at Gleneagles Cancer Institute, Bangalore, is a pioneer in introducing cutting-edge radiosurgical solutions to patients seeking safe and effective cancer care.
Radiosurgery stereotactic is a specialized form of radiation therapy that uses highly focused beams of radiation to destroy abnormal tissues such as tumors, without requiring an open surgical incision. Despite its name, it is not surgery in the traditional sense. Instead, the precision of stereotactic technology allows oncologists like Dr. Mathangi to target diseased areas in the brain, spine, and other organs with sub-millimeter accuracy.
By 2025, radiosurgery has become central to cancer treatment due to:
Many patients ask about stereotactic meaning. The term “stereotactic” comes from the Greek words “stereo” (three-dimensional) and “taxis” (arrangement). It refers to the method of using 3D imaging coordinates to locate and treat very small targets inside the body with extraordinary accuracy. This accuracy makes stereotactic treatment ideal for delicate organs like the brain, spinal cord, and lungs.
Stereotaxic surgery involves using a stereotactic frame or advanced image-guided systems to map a target area in 3D space. Unlike open surgery where physical cutting is required, radiosurgery uses beams of radiation, eliminating the risks of bleeding, infection, or prolonged hospital stays. Under the care of Dr. Mathangi, patients benefit from advanced imaging, planning, and execution that minimize collateral damage to healthy tissues.
Stereotactic treatment is particularly effective for cancers where precision is critical. At Gleneagles Cancer Institute, Dr. Mathangi offers SRS for:
By focusing radiation precisely on the tumor, patients experience fewer side effects while achieving excellent tumor control.
With over 20 years of experience and training from prestigious institutions in Germany and Denmark, Dr. Mathangi has treated more than 12,000 patients successfully. Her expertise in advanced radiotherapy techniques such as Gated RapidArc, SBRT, and image-guided brachytherapy makes her a trusted name in India for cancer care. She was instrumental in bringing Asia Pacific’s first TrueBeam STx machine, enabling world-class treatment in Bangalore.

Book Your AppointmentSRS is a non-invasive technique that uses precisely focused beams to treat small, well-defined lesions—most commonly in the brain and spine—without an incision. It suits patients who need high precision, have tumors in delicate areas, or prefer minimal downtime. Under Dr. Mathangi’s care in Bangalore, candidacy is confirmed through imaging, tumor board review, and an individualized plan.
The term stereotactic meaning refers to a three-dimensional coordinate system that allows clinicians to pinpoint a target with remarkable accuracy. Using MRI/CT fusion and image guidance, Dr. Mathangi maps the lesion and then delivers a sculpted dose that conforms tightly to its shape while protecting healthy tissue around critical structures.
Radiosurgery stereotactic delivers high-dose radiation beams without an incision, anesthesia risks, or prolonged hospitalization. Instead of cutting, the radiation damages tumor DNA so it can no longer grow. Patients typically resume normal activities faster, and the approach is ideal when lesions are deep-seated or surgically risky.
The phrase stereotaxic surgery historically describes frame-based procedures that use a 3D coordinate system to guide instruments. SRS adopts the same coordinate precision but replaces invasive instruments with converging radiation beams. In Dr. Mathangi’s practice, modern frameless immobilization and image guidance provide comfort with the same exactness.
On the day of therapy, immobilization, image verification, and real-time monitoring ensure stereotactic accuracy. You will lie on a treatment couch while the machine arcs around you to deliver the planned dose. Most sessions last 30–60 minutes, and you can usually return home the same day with standard after-care guidance.
Stereotactic treatment is especially valuable for small, well-defined lesions in the brain and spine, as well as select nodules in the lung or liver. In Bangalore, Dr. Mathangi commonly treats brain metastases, meningiomas, vestibular schwannomas, spinal metastases, and isolated pulmonary or hepatic targets after multidisciplinary assessment.
Under the umbrella of advanced radiotherapy, Dr. Mathangi employs image-guided systems, high-dose-rate delivery, motion management (gating), and stereotactic planning with sub-millimeter accuracy. This integrated setup improves dose conformity, reduces exposure to healthy tissue, and supports excellent outcomes with minimal downtime.
Any high-precision therapy has potential side effects, including temporary fatigue, headache, edema around the lesion, or—rarely—radiation necrosis. With radiosurgery, risks are mitigated by meticulous planning, careful dose constraints, and structured follow-up. Patients receive personalized supportive care to manage inflammation and preserve quality of life.
