Radiation therapy, also known as external beam radiation therapy, is a type of cancer treatment that uses high-energy beams to kill cancer cells. Our team of North American and European Board Certified expert hematologists and oncologists offer cutting-edge techniques and advanced technologies to ensure the health and wellbeing of the patient. How is the treatment performed? Radiation therapy is performed using a linear accelerator, a machine that directs high-energy beams of radiation into the patient’s body to target cancerous cells. During the therapy, the linear accelerator moves around to deliver radiation from several angles while the patient is lying down. The linear accelerator can be adjusted for the particular situation to ensure it delivers the precise dose of radiation recommended by the doctor.
