Breast cancer is the most common cancer among women worldwide, and according to the WHO, more than 2.3 million women are diagnosed every year. As treatment becomes increasingly personalized and less invasive, IORT for breast cancer has emerged as a powerful option that offers targeted therapy, reduced treatment time, and excellent clinical outcomes. Patients across India are actively seeking advanced radiation options, and very few centers offer them with the precision and expertise that Dr. Mathangi brings to every case.
This comprehensive guide answers the most common questions women ask about IORT—how it works, its advantages, risks, and why it is rapidly becoming a preferred choice for suitable candidates undergoing breast conserving surgery. With over 20 years of experience and more than 12,000 treated patients, Senior Consultant & In-Charge of Radiation Oncology, Dr. Mathangi at Gleneagles Cancer Institute, Bangalore, is one of India’s foremost experts in advanced radiation therapies including intraoperative radiation therapy breast cancer.
IORT for breast cancer is a technique where a concentrated dose of radiation is delivered directly to the tumor bed during surgery, immediately after the removal of cancerous tissue. It provides immediate treatment at the exact location where cancer recurrence is most likely. This eliminates the delays typically associated with external radiation and ensures high precision.
In the hands of an expert like Dr. Mathangi—who has trained internationally in IORT and stereotactic techniques at globally renowned centers—the technology becomes even more powerful. She ensures that the radiation is shaped, directed, and calculated with exceptional precision, maximizing effectiveness while preserving surrounding healthy tissue.
IORT is commonly paired with breast conserving surgery because it allows the patient to receive radiation “on the table,” reducing the burden of several weeks of daily radiation sessions. For many women, this approach significantly improves convenience and quality of life.
As a leading expert in breast tumor radiation and advanced radiotherapy, Dr. Mathangi has refined patient selection criteria to ensure only those who truly benefit from the technique undergo IORT. Her experience in managing complex breast cancers gives patients confidence during decision-making.
The IORT success rate varies depending on patient selection, tumor characteristics, and adherence to precise radiation guidelines. International studies report recurrence rates comparable to conventional whole-breast radiation in selected early-stage cases.
However, when performed by highly trained specialists like Dr. Mathangi, who integrates global protocols with advanced imaging and radiation planning, patients often experience excellent local control, reduced treatment fatigue, and faster return to daily activities. This strength is especially significant for Indian patients who travel long distances for therapy or cannot commit to extended treatment schedules.
IORT offers multiple benefits that make it a preferred option for suitable breast cancer patients. Below is a quick, snippet-ready summary:
Because Dr. Mathangi has deep expertise in IGRT, RapidArc, SBRT, DIBH techniques, and other advanced modalities, she ensures that IORT is performed with the highest level of accuracy and safety, maximizing all the above benefits.
While IORT is generally safe, like any medical procedure, it carries certain risks. The most common include mild skin reactions, temporary swelling, or seroma formation. Because it delivers a high dose of radiation in a single sitting, it may not be suitable for every patient.
This makes expert evaluation essential. Dr. Mathangi performs detailed multidisciplinary assessments to ensure that radiation is delivered only when the expected benefits outweigh the risks. Her strong background—ranging from interstitial brachytherapy to gated radiotherapy—ensures that complications are minimized and outcomes optimized.
Both IORT and conventional breast tumor radiation aim to eliminate microscopic cancer cells. The difference lies in timing, delivery method, and impact on a patient’s daily life.
| Feature | IORT | Conventional Radiation |
|---|---|---|
| Duration | Single session during surgery | 3–6 weeks daily treatments |
| Radiation field | Highly targeted to tumor bed | Larger portion of the breast |
| Side effects | Fewer, localized | Varies; may include fatigue & skin issues |
| Ideal candidates | Early breast cancer, good margins | Broad applicability |
India’s rising demand for breast cancer treatment India has led many patients to seek treatments that offer both convenience and effectiveness. Under Dr. Mathangi’s guidance, patients receive individualized comparisons to choose the safest and most effective path.
Ideal IORT candidates generally include women with early-stage breast cancer, smaller tumors, and clear surgical margins. However, eligibility is not universal.
At Gleneagles Cancer Institute, Dr. Mathangi uses a comprehensive evaluation protocol that includes:
Her evaluations are guided by her long experience treating complex cancers such as head and neck cancers, lung cancers, prostate cancers, uterine cancers, cervical cancer, and others where radiation therapy plays a key role. This background helps her predict treatment outcomes more accurately and counsel patients effectively.
Few oncologists in India combine advanced international training, technological expertise, and compassionate patient care the way Dr. Mathangi does. She is known not only for her vast clinical experience but also for installing Asia Pacific’s first TrueBeam STx machine—an accomplishment demonstrating her leadership in cutting-edge radiation oncology.
Her approach blends precision, empathy, and scientific rigor. Patients consistently choose her because she:

Intraoperative radiation therapy breast cancer (IORT) is a technique where a concentrated dose of radiation is delivered directly to the tumour bed during surgery immediately after the tumour is removed. It reduces radiation exposure to surrounding healthy tissues and can shorten the overall treatment timeline.
How Dr. Mathangi uses it: she integrates IORT into a coordinated surgical and radiation approach when clinically appropriate.
Many patients eligible for breast conserving surgery may be considered for IORT, but candidacy depends on tumour size, location, pathology, and other health factors. IORT is best suited for select early-stage cancers with favourable features.
Dr. Mathangi provides personalised assessments — she reviews imaging and pathology, discusses options (IORT vs. external beam after breast conserving surgery), and recommends the safest plan tailored to each patient.
Reported IORT success rate varies by study and patient selection; for carefully selected early-stage patients, local control and cosmetic outcomes are comparable to traditional radiation in many series. Long-term follow-up data shows low recurrence for appropriately chosen cases.
During consultation Dr. Mathangi will review outcome data relevant to your specific tumour type and explain the expected benefits and follow-up plan so you can make an informed choice.
IORT concentrates radiation at the surgical site, which can reduce exposure to skin, heart, and lungs versus some external techniques. Side effects may include local wound changes, temporary swelling or tenderness, and rarely changes in skin or delayed healing. Conventional breast tumor radiation over weeks has its own risk profile (skin redness, fatigue), and the trade-offs depend on individual factors.
Dr. Mathangi discusses risks honestly and outlines steps her team takes to minimise complications, including specialised wound care and follow-up imaging.
Recovery from the surgery itself is similar to standard lumpectomy recovery. Because radiation is delivered during the operation, many patients avoid several weeks of daily visits to a radiation centre. Follow-up includes regular clinical exams, mammography, and targeted surveillance recommended by Dr. Mathangi based on your pathology and overall treatment plan.
Yes — breast cancer treatment India includes centres offering IORT as part of their multidisciplinary services. Availability varies by hospital. Dr. Mathangi offers consultations to evaluate suitability, coordinates imaging, pathology review, and the intraoperative radiation delivery, and provides post-operative follow-up and survivorship planning so the entire pathway is seamless.
Bring your imaging (mammograms, ultrasound, MRI if available), biopsy/pathology reports, previous surgical notes (if any), and a list of medications. At the first visit Dr. Mathangi will review these, explain whether IORT or another approach is best, and outline next steps for planning surgery and radiation if indicated.
