Radiation therapy administered from an energy source outside the body and directed to a target inside the body
Radiation treatment for prostate cancer, where a high dose of radiation is delivered from an outside source into the prostate to kill the cancer. The radiation must transverse through healthy tissue to reach the cancerous area. Treatments are generally 5 days a week for 7-8 weeks. Each treatment last only a few minutes. Newer forms of external beam radiation, called three-dimensional conformal radiation (3D-CRT) and intensity modulated radiotherapy (IMRT) more accurately target the prostate and are considered the preferred method when using external beam radiation for the initial treatment of prostate cancer. With these newer therapies the patient is immobilized and subjected to radiation beams aimed from several directions.
(EBRT): a form of radiation therapy in which the radiation is delivered by a machine directed at the area to be radiated as opposed to radiation given within the target tissue such as brachytherapy, see also IMRT
The use of radiation as treatment for cancer. The radiation is produced by equipment external to the body, and a tightly focused beam of energy is directed to the area to be treated to kill cells or slow their growth.
Radiation treatment delivered from a machine. See Radiation therapy.
Radiation therapy that uses a machine outside of the body to deliver high-energy rays directed at the cancer or tumor.
A form of radiation therapy in which radiation from an outside source is focused on the on the prostate gland to kill cancer cells.
Radiation therapy that uses photon (light) rays from a machine directed toward parts of the body.
radiation therapy provided by machines that aim special radiation beams at the prostate to destroy cancer cells.
The sending of radiation from outside the body toward a tumor or potential tumor site inside the body.
Treating cancer and other disorders with the use of radiation. Sometimes it is called radiation therapy.
A 25-28 treatment protocol that utilizes External Beam Radiation. Approximately 6800-7400 rads of radiation energy is delivered to the Prostate. There can be some radiation effect on surrounding tissues.
Any type of radiation therapy in which the radiation source is located at a distance from the patient's body (see also brachytherapy ).
A form of radiation therapy that utilizes radiation delivered by an external source (machine) and directed at a target area to be radiated. In contrast to EBRT, brachytherapy utilizes radiation sources (seeds) that are internal, implanted in the target tissue. EBRT may use conventional photons, protons, neutrons or electrons.
Radiation therapy in general is the use of high-energy radiation from x-rays, gamma rays, and other sources to kill cancer cells and shrink tumors. When the source of the radiation comes from a machine outside the body it is called external-beam radiation therapy.
A therapy in which a radiation beam from outside of the body targets cancer on the inside of the body. Also called EBRT
Radiation therapy that is given by directing a beam of radiation at the cancer from a source located outside of the body.
irradiation of an area of disease (usually cancerous) using an external source of radiation in order to destroy the diseased tissue. Dividing cells are more susceptible to radiotherapy as their DNA is vulnerable to radiation-induced breaks
