External Beam Radiation Therapy (EBRT) is a non-invasive treatment that uses high-energy X-rays or gamma rays to target and destroy cancer cells. The radiation is delivered from outside the body using a machine called a linear accelerator. EBRT is commonly used for many cancers, either alone or in combination with surgery and chemotherapy.
EBRT is a type of radiation treatment where a machine directs high-energy beams to a specific area of the body to kill or shrink cancer cells. It is painless and performed on an outpatient basis, meaning patients usually do not need to stay in the hospital.
EBRT is used to treat many cancers, including:
It may also be used to relieve symptoms such as pain, bleeding caused by advanced cancer or metastatic disease
Before treatment begins, patients undergo simulation and planning scans (CT/MRI) to map the exact tumor location. During treatment:
Each session lasts 15–30 minutes and is usually given 5 days a week for several weeks
No. The treatment itself is painless. Patients may hear the machine and need to remain still, but they do not feel the radiation. Side effects may occur gradually over the course of treatment. Side effects depends on the dose, fractions, and where we give the treatment.
Side effects depend on the area treated and may include:
Most side effects are temporary and manageable with supportive care.
EBRT is highly effective for many cancers, either as a curative treatment (to eliminate cancer) or palliative treatment (to relieve symptoms). Success depends on cancer type, stage, and the overall health of the patient.
Patients will have regular follow-up visits to monitor response and manage any side effects. Imaging tests may be ordered to check tumor control. Long-term lifestyle changes, including good nutrition and exercise, help improve recovery.
