Radiation Therapy involves the treatment of cancer with high energy X-rays. Today, Radiation Therapy is delivered using very sophisticated state-of-the-art equipment, computers and treatment planning capabilities to selectively pinpoint and treat areas while minimizing radiation dose to normal tissues.
Radiation Therapy is typically administered by a sophisticated machine called a Linear Accelerator that produces a high-energy x-ray beam which is externally delivered to the appropriate area of the body. This is called External Beam Radiation Therapy. In certain cases, radiation seeds or sources can be placed into the body, either permanently or temporarily. This is called Brachytherapy or Seed Implantation.
Radiation Therapy can be used alone as the only treatment for cancer. Often it may be combined with chemotherapy or surgery.
