The use of high-energy radiation from x-rays, gamma rays, neutrons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body in the area near cancer cells (internal radiation therapy, implant radiation, or brachytherapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that circulates throughout the body. Also called radiotherapy.
Treatment for some diseases, e.g., cancer, using a variety of forms of radiation, X-ray, and radioactive isotopes.
Use of radioactive elements as diagnostic and therapeutic interventions.
Treatment by X-rays or other forms of radiation; used to treat cancer and other diseases.
Also known as radiotherapy; treatment of malignant (cancerous) tumors and benign (not cancerous) conditions using X rays or radionuclides. Radiation therapy is the use of high-energy radiation to destroy or shrink malignant or benign cells by carefully regulating the dose and by targeting to the treatment site.
The use of energy from man-made ionizing radiation or from the radioactive decay of atomic nuclei to destroy diseased tissues, especially cancers.
The use of high-energy radiation to kill cancer cells.
Use of radiation either to destroy cancer cells or to destroy their reproductive mechanism so they cannot replicate.
A therapeutic approach for cancer management involves the application of high-energy rays to eliminate or debilitate cancerous cells. Radiation can be administered externally or internally through surgically implanted pellets.
