Over 50% of all cancer patients receive radiotherapy during their treatment, according to the World Health Organization. This highlights the significance of understanding the radiotherapy definition and how it is used to manage cancer effectively. At the forefront of this science is Dr. Mathangi J, Senior Consultant and Head of radiation oncology at Gleneagles Cancer Institute, who brings over 15 years of global and clinical expertise to this vital field.
Let’s begin with the radiotherapy definition: Radiotherapy is a form of medical radiation that uses high-energy rays or particles to destroy cancer cells. This technique may be used as a primary treatment, adjuvant therapy, or for palliative care. Understanding radiotherapy basics helps patients approach treatment with clarity and confidence.
Radiation oncology is the branch of medicine that deals with using radiation to treat cancer. It combines advanced physics, imaging, and medical expertise to deliver highly focused therapy. Dr. Mathangi leads this department at Gleneagles with excellence, offering the latest protocols and technology-driven cancer care.
Ionizing radiation is the type of radiation used in therapy because it carries enough energy to damage the DNA inside cancer cells. By disrupting this DNA, cells can no longer grow or divide, leading to their eventual death. Techniques like IGRT, SBRT, and SRS — all practiced by Dr. Mathangi — enhance the safe and effective delivery of this powerful energy.
Cancer cell destruction is the ultimate goal of radiation therapy. When exposed to ionizing radiation, cancer cells absorb the energy, causing breaks in their DNA strands. Unlike healthy cells, cancer cells cannot repair this damage efficiently, leading to controlled cell death. Dr. Mathangi ensures this process is carefully calculated to preserve surrounding healthy tissue.
Targeted therapy in oncology often refers to drugs, but radiation can be just as precise. With technologies like RapidArc, DIBH, and TrueBeam STx, Dr. Mathangi delivers high-dose radiation directly to the tumor with millimeter accuracy. This form of targeted therapy reduces side effects while maximizing treatment success.
The primary treatment goals of radiotherapy vary based on the cancer type and stage. These goals can be:
At Gleneagles, Dr. Mathangi ensures these goals are clearly discussed with every patient, building a personalized treatment roadmap.
Modern radiotherapy includes several cutting-edge techniques, all of which are available under Dr. Mathangi’s supervision:
One of the most common concerns patients have is: “Is radiation safe?” With the guidance of experienced specialists like Dr. Mathangi and the use of real-time imaging, safety margins, and dosage controls, radiotherapy is now safer than ever before. Side effects are minimized, and treatments are monitored continuously for maximum benefit and lowest risk.
With over 12,000 cancer patients successfully treated, Dr. Mathangi stands as a national leader in advanced radiotherapy. She is the first in Asia-Pacific to install the TrueBeam STx system and is the Director of the Fellowship in Advanced Radiotherapy Techniques at RGUHS. Her dedication to personalized care and safety makes her one of the most trusted experts in radiation oncology today.
If you or your loved one is preparing for radiation therapy, the first step is to get evaluated by an experienced radiation oncologist. Dr. Mathangi and her team will provide a detailed consultation, explain every step of the process, and create a personalized treatment plan tailored to your needs and comfort.
