The history of radiation therapy or radiotherapy can be traced back to experiments made soon after the discovery of X-rays (1895), when it was shown that exposure to radiation produced cutaneous burns. Influenced by electrotherapy and escharotics —the medical application of caustic substances—doctors began using radiation to treat growths ...
Radiation therapy or radiotherapy (RT, RTx, or XRT) is a treatment using ionizing radiation, generally provided as part of cancer therapy to either kill or control the growth of malignant cells. It is normally delivered by a linear particle accelerator .
1896 – French Dr. Victor Despeignes, "the father of radiation therapy", starts to use X-rays to treat cancer [ 8 ] 1896 – American Dr. Emil Grubbe starts to treat breast cancer patients with X-rays [ 4 ] 1896 Sir George Thomas Beatson invented hormonal treatment of breast cancer by bilateral ovary removal in women with inoperable breast cancer.
1423298. [edit on Wikidata] Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer. Radiosurgery was originally defined by the ...
External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. A radiotherapy beam is composed of particles which travel in a consistent direction; each radiotherapy beam consists of one type of particle intended ...
Image-guided radiation therapy is the process of frequent imaging, during a course of radiation treatment, used to direct the treatment, position the patient, and compare to the pre-therapy imaging from the treatment plan. [1] Immediately prior to, or during, a treatment fraction, the patient is localized in the treatment room in the same ...
Radionuclide therapy. Radionuclide therapy (RNT, also known as unsealed source radiotherapy or molecular radiotherapy) uses radioactive substances called radiopharmaceuticals to treat medical conditions, particularly cancer. These are introduced into the body by various means (injection or ingestion are the two most commonplace) and localise to ...
Intraoperative radiation therapy (IORT) is radiation therapy that is administered during surgery directly in the operating room (hence intraoperative). Usually therapeutic levels of radiation are delivered to the tumor bed while the area is exposed during surgery. IORT is typically a component in the multidisciplinary treatment of locally ...
