Nearly half of all cancer patients worldwide undergo radiation therapy during their treatment journey. With rising survival rates and rapid technological progress, advanced radiotherapy techniques now play a decisive role in improving both precision and safety. For patients in Bangalore, Dr Mathangi J, Senior Consultant & In-charge of Radiation Oncology at Gleneagles Cancer Institute, stands at the forefront of this progress.
Modern cancer care demands accuracy. Conventional methods can harm surrounding healthy tissues, but the latest radiotherapy techniques allow oncologists to concentrate energy precisely where it’s needed. Under the guidance of Dr Mathangi J, a highly respected radiation oncologist in Bangalore, each treatment is planned using the most suitable approach—balancing tumour control with patient comfort.
Her approach focuses on protecting quality of life while ensuring maximum tumour control. By harnessing image guidance, beam modulation, and motion management, patients receive treatments that are both effective and gentle. Missing this level of precision could mean missing a chance at the best possible outcome.
Each form of radiotherapy offers distinct advantages depending on tumour type, size, and location. Below is a simplified overview of commonly used technologies at Dr Mathangi’s centre.
| Technique | How it works | When it’s used |
|---|---|---|
| 3D-CRT | Three-Dimensional Conformal Radiation Therapy uses imaging to shape radiation beams that conform to the tumour, minimizing exposure to nearby healthy tissue. | Suitable for tumours with defined borders, where moderate dose precision is required. |
| IMRT | Intensity-Modulated Radiation Therapy adjusts the intensity of beams across multiple angles, delivering precise doses to irregularly shaped tumours. | Commonly used for head-and-neck, prostate, and pelvic cancers where vital structures are nearby. |
| IGRT | Image-Guided Radiation Therapy integrates real-time imaging during treatment, ensuring the target area remains perfectly aligned at every session. | Ideal for lung, liver, or abdominal tumours where breathing or movement affects accuracy. |
| SBRT | Stereotactic Body Radiation Therapy delivers high doses in fewer sessions with millimetre accuracy, often substituting for surgery in small, localized tumours. | Highly effective for lung nodules, liver lesions, or isolated metastases. |
| Stereotactic radiotherapy | This ultra-precise method targets brain or spine tumours using multiple converging beams, minimizing dose to normal brain tissue. | Preferred for brain metastases or spine tumours where surgical risks are high. |
| Brachytherapy | Internal radiation places radioactive sources close to or inside the tumour, allowing high doses directly at the site. | Widely used for prostate, cervical, and breast cancers where localized radiation achieves optimal results. |
| Proton therapy | This technique uses charged protons rather than photons, depositing energy precisely at the tumour while sparing surrounding organs. | Beneficial for tumours near critical organs and for select head, neck, or paediatric cases. |
At Gleneagles Cancer Institute, every patient’s journey begins with a detailed consultation and imaging assessment. Dr Mathangi J personally supervises treatment planning, leveraging cutting-edge systems like the TrueBeam STx—the first of its kind in the Asia-Pacific region. This technology enables rapid delivery of highly accurate radiation beams with minimal patient discomfort.
Dr Mathangi’s extensive international training in Germany, Denmark, and other leading global centres ensures that patients in Bangalore receive treatment on par with international standards. Her expertise bridges compassion and innovation, making her one of the most trusted figures in radiation oncology.
Advanced radiotherapy techniques are pivotal for cancers that demand high precision to protect surrounding organs. Under Dr Mathangi’s care, patients with the following conditions often benefit:
For each cancer type, Dr Mathangi J carefully selects the appropriate modality—whether it’s IMRT for head-and-neck, SBRT for lung lesions, or brachytherapy for cervical cases—to maximise tumour control while maintaining patient comfort.
The advantage of these advanced systems lies in their precision. Patients experience:
With real-time imaging and dose modulation, treatments can be adapted even during a session, offering unparalleled safety. However, the success of these techniques depends greatly on the skill of the specialist administering them—making Dr Mathangi’s oversight invaluable.
Every patient’s condition is unique. If you’ve been advised radiation therapy, a detailed consultation will determine whether you require IMRT, IGRT, SBRT, or any other advanced approach. Through sophisticated planning and evaluation, Dr Mathangi J ensures that each treatment is individually optimised.

Below are concise, clinic-ready answers from Dr. Mathangi J, Senior Consultant & In-charge of Radiation Oncology, Gleneagles Cancer Institute, Bangalore. Use these to quickly understand options and book the most suitable consultation pathway for your case.
Advanced radiotherapy techniques use imaging, beam-modulation, and motion control to maximise tumour dose while protecting healthy organs. Dr. Mathangi recommends them when the tumour is close to critical structures (brain, spine, head-and-neck), when daily motion matters (lung, liver), or when faster, high-precision schedules can safely reduce overall treatment time.
IMRT (Intensity-Modulated Radiation Therapy) sculpts dose by varying beam intensity across many angles, achieving superior conformity around complex shapes. 3D-CRT conforms the outer beam to the tumour’s 3D outline but does not modulate intensity within each beam. In many head-and-neck and prostate cases, IMRT helps reduce dry mouth, rectal irritation, or bladder exposure versus traditional plans.
IGRT (Image-Guided Radiation Therapy) verifies tumour position at each session using onboard imaging and adjusts the patient setup accordingly. This matters for lung, liver, and abdominal targets where daily motion can blur dose placement. Under Dr. Mathangi, IGRT reduces “misses,” allowing tighter margins and better organ protection.
SBRT delivers very high, ablative doses over a few sessions—often 1–5—using millimetre-level targeting. It’s typically chosen for small, well-defined tumours in lung, liver, spine, or oligometastatic disease when surgery is risky or not preferred. The schedule and dose are individualised after imaging, motion assessment, and risk review.
stereotactic radiotherapy uses multiple finely focused beams and image guidance to converge a high dose on the target while sparing surrounding tissue. Compared with conventional courses, it achieves higher biological doses in fewer visits, which can be crucial for brain or spine lesions and select lung or liver nodules treated at Dr. Mathangi’s centre.
brachytherapy places a radiation source inside or beside the tumour, delivering a high dose right where it’s needed. It’s valuable for cervical, prostate, and select breast cases. Depending on the site, the procedure may be outpatient or short-stay, with careful imaging, applicator placement, and personalised dose planning by Dr. Mathangi’s team.
proton therapy uses charged particles that deposit most of their energy at a specific depth (the Bragg peak), reducing exit dose. It’s considered when critical organs must be spared—such as base-of-skull or certain head-and-neck sites. Dr. Mathangi advises on suitability, access pathways, and complementary photon techniques when appropriate.
As a seasoned radiation oncologist in Bangalore, Dr. Mathangi combines international training with high-end platforms (including TrueBeam STx) to personalise care across complex sites. Her protocols integrate IMRT, IGRT, SBRT, 3D-CRT, brachytherapy, proton therapy, and stereotactic radiotherapy as indicated—streamlining evaluation, treatment, and follow-up for optimal outcomes.
