EBRT is delivered by Linear Accelerator by which traverses the body from outside to inside. Most Patients receives EBRT in daily sessions which are spread over several weeks depending on the disease and stage. EBRT can be delivered in various forms. Using a special X-ray machine called a linear accelerator, EBRT delivers high-energy rays to tumors. The machine delivers radiation from any angle and shapes radiation beams to thecontour of the tumor. The machine moves around the body without touching the patient, aiming radiation at the cancer. Some types of focused EBRT target a tumor with higher, more precise doses of radiation, while reducing damage to healthy tissue and nearby organs. As a result, EBRT may help reduce the risk of side effects associated with traditional radiation treatment.
