Modern oncology has entered an era where precision defines survival. The evolution of stereotaxic surgery—a highly targeted, three-dimensional cancer treatment technique—has transformed outcomes for patients with complex tumours. This approach has significantly improved tumour control rates while preserving healthy tissue. In Bangalore, Dr. Mathangi J, Senior Consultant and In-charge of Radiation Oncology at Gleneagles Cancer Institute, is among the foremost experts offering this advanced treatment for patients across India.
Stereotaxic surgery is a precise, image-guided method that allows doctors to locate and treat deep-seated or complex tumours within the body using a three-dimensional coordinate system. It can involve both surgical and radiation-based techniques, depending on the type and location of the tumour. The process enables clinicians to focus treatment energy exactly where it is needed—limiting exposure to healthy tissues and reducing recovery time.
At Gleneagles Cancer Institute, under the leadership of Dr. Mathangi J, this technology is not just a procedure—it’s a promise of precision, compassion, and cutting-edge care for patients battling cancers in critical organs such as the brain, spine, liver, lung, prostate, and breast.
While both aim to treat tumours with high precision, stereotaxic surgery is the umbrella technique that may use mechanical or radiation-based tools, whereas radiosurgery specifically refers to a non-invasive method that uses focused radiation beams to destroy tumour cells without incisions. Radiosurgery is particularly effective for patients with brain, lung, or spine tumours where surgical access is challenging. At Gleneagles, both modalities are employed depending on the patient’s condition and treatment goals.
The phrase stereotactic meaning revolves around accuracy and control. Derived from “stereo” (three-dimensional) and “tactic” (arrangement), it signifies a method that uses 3D coordinates to navigate within the human body. This technology allows oncologists like Dr. Mathangi to deliver targeted therapy with remarkable precision—minimising risks and maximising outcomes for each patient.
A stereotactic procedure begins with advanced imaging such as CT, MRI, or PET scans to map the exact location of the tumour. A specialised frame or mask system ensures the patient remains still during treatment. Using computer-guided planning, a detailed 3D model of the tumour is created. This model directs the radiation beams or surgical instruments to the exact coordinates, allowing treatment delivery with sub-millimetre accuracy.
At Dr. Mathangi’s centre, each stereotactic procedure is planned through multidisciplinary discussions involving radiation oncologists, medical physicists, and radiologists, ensuring safety and precision at every step.
Brain stereotaxic surgery is one of the most remarkable applications of this technique. It is used to target tumours, vascular malformations, and certain functional disorders without requiring large incisions. For patients who cannot undergo open brain surgery due to tumour location or overall health, stereotaxic approaches offer hope. The precision achieved ensures that delicate brain structures remain unaffected, preserving neurological function and improving recovery time.
The success of stereotaxic surgery lies in its ability to combine precision with safety. Here are some key benefits:
While the outcomes of stereotaxic surgery are outstanding, understanding potential risks is essential for informed decision-making. Some patients may experience temporary swelling or mild fatigue after treatment. In rare cases, radiation to nearby healthy tissue may cause transient discomfort or inflammation. Tumour size and proximity to critical organs can also influence candidacy for this approach.
At Gleneagles, these risks are meticulously managed through advanced image-guided systems, real-time dose monitoring, and strict adherence to international radiation safety protocols. Patients are counselled thoroughly before undergoing treatment to ensure comfort and clarity.
Under the care of Dr. Mathangi J, stereotaxic approaches are integrated into personalised cancer care plans for various conditions, including:
When it comes to stereotaxic and radiosurgical treatments, expertise determines outcomes. Dr. Mathangi J combines over two decades of clinical experience with extensive international training from leading cancer institutes in Germany and Denmark. She has treated more than 12,000 patients and leads a team equipped with the Asia-Pacific region’s first TrueBeam STx Machine—an advanced linear accelerator known for sub-millimetre precision and reduced side effects.
Her leadership in technologies such as Stereotactic Ablative Body Radiotherapy (SBRT), Gated RapidArc, and Image-Guided Interstitial Brachytherapy ensures that every patient receives globally benchmarked care. Her calm and empathetic approach reassures patients at every step of their journey—from diagnosis to recovery.
Patients seeking consultation with Dr. Mathangi can prepare by compiling their medical and imaging records, noting down any prior treatments, and listing their questions. During the consultation, each case is carefully reviewed to assess the suitability of stereotaxic techniques and create a customised treatment plan. To book an appointment, simply submit your contact details on Dr. Mathangi’s contact page, and her team will arrange your session promptly.
Cancer is a battle where timing determines advantage. The earlier advanced options like stereotaxic surgery are considered, the higher the probability of success. Delays can limit the scope of minimally invasive options. Dr. Mathangi’s centre provides rapid assessment and treatment planning, ensuring patients get access to timely and effective interventions.

Below are concise, patient-friendly answers curated by Dr. Mathangi J, Senior Consultant & In-charge of Radiation Oncology, Gleneagles Cancer Institute, Bengaluru. Use these to quickly understand choices, benefits, and safety before you book a consultation.
In plain language, stereotaxic surgery is a highly precise, image-guided technique that treats deep or delicate tumors using a 3D coordinate system. It helps your care team focus treatment energy on the tumor while protecting healthy tissue, often resulting in shorter recovery and fewer side effects under Dr. Mathangi’s protocol-driven planning.
Think of stereotaxic targeting as the method, and radiosurgery as one way to deliver treatment. Radiosurgery uses focused radiation beams—no incision—to destroy tumor cells with surgical accuracy. Dr. Mathangi selects between these modalities (or combines them with other therapies) based on your tumor’s site, size, prior treatments, and personal goals.
The phrase stereotactic meaning highlights 3D precision. Your scans (CT/MRI/PET) define coordinates that guide beams or instruments directly to the lesion. This accuracy helps reduce dose to nearby organs, lowers complications, and supports faster return to daily routines when planned and delivered by experienced teams like Dr. Mathangi’s.
Patients with well-defined lesions in the brain, spine, lung, liver, or prostate often qualify for a stereotactic procedure. Suitability depends on tumor size, number, location, your overall health, and any previous therapies. During consultation, Dr. Mathangi reviews imaging, pathology, and history to tailor a plan that prioritizes tumor control and safety.
For brain stereotaxic surgery, you’ll undergo high-resolution imaging and careful immobilization (frame or mask). Advanced software maps the tumor in 3D, allowing sub-millimetre targeting. Treatment may be completed in a single session or a few short sessions. Most patients go home the same day with clear post-care guidance from Dr. Mathangi’s team.
Benefits: no large incisions, high precision, fewer sessions, and typically faster recovery. Risks: temporary swelling, fatigue, or rare effects in nearby tissue, which are minimized through meticulous planning and dose constraints. Dr. Mathangi explains your personalized benefit–risk profile and documents all safety checks before treatment.
Many plans finish in one to five sessions, each typically under an hour, though complex cases may vary. Most patients resume light routines within 24–72 hours. You’ll receive a written after-care sheet and follow-up schedule; if needed, supportive medications are prescribed to keep you comfortable.
