Types of Radiation Therapy Delivery

External Beam Radiation Therapy  Read More...

External-beam radiation therapy is most often delivered in the form of photon beams (either x-rays or gamma rays). A photon is the basic unit of light and other forms of electromagnetic radiation. It can be thought of as a bundle of energy. External beam radiation therapy consists of several different methods of delivering radiation with photons from an external source into the patient’s body to treat the cancer. 

Particle Beam Radiation Therapy  Read More...

Particle beam radiation therapy delivers radiation by accelerating charged particles such as protons, carbon or other heavier ions. These particle beams can carry very high energy and travel through the body with the ability to stop at a specific location (where the cancer cells are located). This important feature is utilized to destroy the tumor and spare the healthy tissues as much as possible. In the last decade, the significant radiobiological and clinical advantages of particle therapy have been quickly realized with a rising number of proton therapy centers opening in the United States and the world.

Brachytherapy  Read More...

Brachytherapy is radiation delivered from radiation sources (radioactive materials) placed inside or on the body. Doctors can use brachytherapy alone or in addition to external-beam radiation therapy to provide a “boost” of radiation to a tumor while sparing surrounding normal tissue. Brachytherapy may be able to deliver higher doses of radiation to some cancers than external-beam radiation therapy while causing less damage to normal tissue.

Systemic Radiation Therapy  Read More...

In systemic radiation therapy, patients swallow or receive an injection of a radioactive substance, such as a radioactive isotope or a radioactive isotope bound to a monoclonal antibody.
