Radiation Therapy History

Its more commonly used in abdominal or pelvic cancers and in cancers that tend to recur come back after treatment. Radiation therapy has been in use for the treatment of cancer and other diseases for approximately 100 years.

Short overview on history of medical radiation.

Radiation therapy history. Radiation therapy is one of three major modalities available to treat malignant disease the other two major modalities being chemotherapy and surgery. As there is no exit dose when using proton radiation therapy the dose to surrounding normal tissues can be significantly limited reducing the acute toxicity which positively impacts the risk for these long term side effects. History of radiation therapy.

Doctors known as radiation ocologists oversee radiation therapy which usually consists of a specific number of treatments given over a set period of time. External beam radiotherapy ebrt is the most common form of radiotherapy radiation therapythe patient sits or lies on a couch and an external source of ionizing radiation is pointed at a particular part of the body. In contrast to brachytherapy sealed source radiotherapy and unsealed source radiotherapy in which the radiation source is inside the body external beam radiotherapy directs.

Radiation induced secondary malignancy is another very serious adverse effect that has been reported. In addition to treating cancer radiation oncologists may also use ionizing radiation to treat benign tumors that are unable to be removed by surgery. Intraoperative radiation therapy iort is a form of treatment that delivers radiation at the time of surgery.

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 burnsinfluenced by electrotherapy and escharotics the medical application of caustic substances doctors began using radiation to treat growths and lesions produced by diseases such as lupus. For example malignant cells are usually killed by ionizing radiation. Is known to destroy cancer cells.

The radiation can be given directly to the cancer or to the nearby tissues after the cancer has been removed. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. Using a thin aluminum window that allowed light to exit the tube while maintaining the necessary vacuum he observed.

The decision to use radiation therapy is guided by specific indications of disease. 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. The german physicist wilhelm rontgen figure 1 1 discovered the radiation known today as x rays or rontgen rays on 8th november 1895 while investigating the external effects of radiation from various types of vacuum tubes.

Radiation therapy radiation therapy indications for radiation therapy. As early as 1897 it was concluded that x rays could be used for therapeutic as well as diagnostic purposes and in 1912 marie curie published the theory of radioactivity. Radiation therapy the use of ionizing radiation high energy radiation that displaces electrons from atoms and molecules to destroy cancer cells.
