Did you know that nearly half of all patients undergoing cancer treatment will at some point benefit from radiation therapy? In fact, studies show that radiation is involved in approximately 50% of curative-intent treatments. At the heart of this is the field of radiation oncology, where technology meets human care. At the Gleneagles Cancer Institute in Bangalore, under the leadership of Dr Mathangi J, Senior Consultant & In-Charge of Radiation Oncology, this blend of science and compassion takes centre stage.
Radiation oncology is the branch of medicine that uses targeted energy called ionizing radiation to destroy cancer cells or inhibit their growth. It is a major pillar of modern cancer treatment alongside surgery and systemic therapies. For patients facing a diagnosis such as a tumour in the lung, brain, prostate or head and neck region, radiotherapy offers a precise option to eradicate disease while preserving normal tissues.
In simplest terms, radiotherapy delivers high-energy beams that damage the DNA of cancer cells, causing them to die or stop dividing. The process relies on careful planning to balance the destruction of malignant tissue with the protection of healthy organs. At Gleneagles, Dr Mathangi’s team uses the latest algorithms and imaging to map treatment volumes, identify critical structures, and deliver therapy with sub-millimetre accuracy.
Stereotactic radiosurgery (SRS) or stereotactic body radiotherapy (SBRT) delivers very high doses of radiation in one or few sessions to a well-defined target. This technique is ideal for small tumours in the brain, lung, liver or spine, allowing non-invasive, outpatient treatment in many cases. Under Dr Mathangi’s care, patients with complex lesions such as brain tumours or spine metastases have access to this cutting-edge option with safety and precision.
The incorporation of real-time imaging (IGRT) and motion control (such as gating for breathing) means that the radiation beams adapt to the patient’s anatomy and movement. These innovations reduce dose to normal organs and enhance tumour targeting—making the difference in outcomes and side-effects. Dr Mathangi emphasises that combining the best technology with compassionate patient-centred workflow is what defines modern radiation oncology practice.
At the heart of Dr Mathangi’s practice is a wide spectrum of tumour types where radiation plays a key role. These include:
By offering a full range of indications, Dr Mathangi ensures that patients are evaluated in a multidisciplinary setting and receive personalised radiation plans tailored to their situation, needs and goals.
One might ask: Why choose Dr Mathangi and her team for your radiation needs? The answer lies in the three-fold commitment to expertise, innovation and empathy.
With over 20 years of experience and more than 12,000 successfully treated patients, Dr Mathangi brings deep technical proficiency and clinical judgment to every case. Her credentials (MBBS, DMRT, DNB) and advanced training in Germany (for SRS/SBRT), Denmark (IGRT/RapidArc) and other global institutions underline her dedication to staying at the forefront of radiation oncology.
The installation of the TrueBeam STx platform, and the integration of other “advanced radiotherapy techniques”, gives patients access to world-class tools in Bangalore. Whether it’s SBRT for lung oligometastases, DIBH gating for breast cancer, or image-guided brachytherapy for cervix, the technology is matched by a culture of continual improvement.
Technical skill alone is not enough. Dr Mathangi and her team believe that each patient is more than a diagnosis—they are a person with hopes, fears, family and life beyond cancer. From pre-treatment counselling to side-effect management and survivorship planning, the element of empathy is woven into every stage. Many patients say they ‘felt cared for’ in ways that matter just as much as the treatment itself.
If you or a loved one are considering radiation, here are some practical steps to prepare and get the most from your care:
In many cancers, timely delivery of radiation therapy can dramatically improve outcomes. With key conditions like head and neck cancer, lung cancer or prostate cancer, delays or sub-optimal techniques can reduce chances of cure or raise toxicity. At Gleneagles, the workflow under Dr Mathangi is streamlined—from planning to delivery—to ensure minimal delays and maximum precision. That means patients are not simply waiting—they are actively moving toward recovery.
Dr Mathangi J is a Senior Consultant & In-Charge of Radiation Oncology at Gleneagles Cancer Institute, Bangalore. She completed her DMRT at Madras Medical College, Chennai, and her DNB residency at Apollo Cancer Specialty Hospital, Chennai. She received advanced training in SRS/SBRT at Klinikum Frankfurt (Oder), Germany; IGRT/RapidArc at Copenhagen University Hospital (Rigshospitalet), Denmark; and intra-operative radiotherapy (IORT) from 4EIEVSEN. Under her leadership the radiation oncology department has treated over 12,000 patients using cutting-edge technology including TrueBeam STx, Gated RapidArc, DIBH gated Radiotherapy and image-guided interstitial brachytherapy.

Below are concise, patient-friendly answers to common questions about care with Dr. Mathangi at Gleneagles Cancer Institute, Bangalore. Tap a question to expand the answer.
Radiation oncology is a medical specialty that uses ionizing radiation to precisely target tumors while protecting healthy tissue. Under Dr. Mathangi’s leadership, the team pairs advanced planning, clear communication, and gentle side-effect management to deliver radiotherapy as part of holistic cancer treatment that respects your goals, time, and comfort.
Radiotherapy is recommended for many tumor sites—brain, lung, prostate, breast, cervix, and head and neck cancer—either to cure, to improve local control, or to relieve symptoms. With meticulous contouring and advanced radiotherapy techniques, Dr. Mathangi aims for strong control rates and fewer complications, while keeping you informed about benefits, timelines, and follow-up.
Stereotactic radiosurgery delivers very high, pinpoint-accurate doses over one to a few sessions, ideal for small, well-defined targets in the brain, spine, lung, or liver. It contrasts with conventional multi-week courses by compressing treatment time and minimizing exposure to nearby organs—an approach Dr. Mathangi optimizes using the precision of TrueBeam STx and image guidance.
TrueBeam STx couples rapid, image-guided delivery with sub-millimetre accuracy, supporting stereotactic workflows and respiratory gating. For eligible patients, this can translate into shorter sessions, tighter dose sculpting, and better protection of healthy organs. Under Dr. Mathangi’s protocols, the platform anchors a safe, efficient pathway from planning to completion.
Side effects are reduced through precise imaging (CT/MRI/PET), motion management (gating/DIBH), daily verification, and personalized dose constraints. By tailoring fields and using advanced radiotherapy techniques, the team keeps sensitive organs within safe limits, then supports you with nutrition, skin care, oral care, and evidence-based medications throughout radiotherapy.
Head and neck cancer planning demands millimetre-level accuracy to spare salivary glands, swallowing structures, and the spinal cord. Dr. Mathangi combines meticulous contouring, adaptive image guidance, and symptom-led care (for mouth sores, dry mouth, nutrition) to protect function while maintaining tumor control, all with compassionate counseling and timely follow-ups.
Bring prior scans, pathology, treatment summaries, medicines list, and your questions. Comfortable clothing helps for simulation. To book, submit your details at drmathangi.com/contact. The team will schedule your consultation, explain your plan, and guide you through each step of cancer treatment.
Conventional courses can run 1–6 weeks on weekdays, while stereotactic schedules may finish in 1–5 visits. Start times depend on simulation, contouring, and quality checks—steps that ensure accuracy and safety. Dr. Mathangi’s streamlined workflow aims to minimize waiting while preserving the exactness that underpins effective radiotherapy.
