Radiation Therapy Definition

Radiation therapy definition radiation therapy sometimes called radiotherapy x ray therapy radiation treatment cobalt therapy electron beam therapy or irradiation uses high energy penetrating waves or particles such as x rays gamma rays proton rays or neutron rays to destroy cancer cells or keep them from reproducing. The use of high energy rays to damage cancer cells stopping them from growing and dividing.

Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.

Radiation therapy definition. The term radiation therapy most often refers to external beam radiation therapy. It may be delivered externally through external beam radiation therapy and a linear accelerator or a number of other delivery types. Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells.

Radiation may come from a machine outside the body external beam radiation therapy or it may come from radioactive material placed in the body near cancer cells internal radiation therapy or brachytherapy. Radiation therapy or radiotherapy often abbreviated rt rtx or xrt is therapy using ionizing radiation generally as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Purpose the purpose of.

Radiation can come from a machine external radiation or from a small container of radioactive material implanted directly into or near a tumor internal radiation. The use of high energy radiation from x rays gamma rays neutrons protons and other sources to kill cancer cells and shrink tumors. Radiation therapy is used to kill cancer cells and shrink tumors.

Like surgery radiation therapy is a local treatment that affects cancer cells only in the treated area. Radiation therapy most often uses x rays but protons or other types of energy also can be used.
