radiation therapy

   Also found in: Dictionary/thesaurus, Medical, Legal, Acronyms, Wikipedia 0.02 sec.

radiation therapy

 or radiotherapy or therapeutic radiology

Use of radiation sources to treat or relieve diseases, usually cancer (including leukemia). The ionizing radiation primarily used to destroy diseased cells works best on fast-growing cancers. However, radiation can also cause cancer (see radiation injury) and is no longer used for benign conditions. Other complications include nausea, hair loss, weight loss, and weakness. Radioactive substances may be implanted in tumours (see nuclear medicine). External radiation involves 10–20 sessions over several months, either after surgical removal of the growth or when surgery is impossible; it can deliver higher doses to deep tumours than implantation. Infrared radiation and ultraviolet radiation is applied with lamps to relieve inflammation.
