How does radiation therapy work?
Radiation therapy works by damaging the DNA of cancerous cells. This DNA damage is caused by one of two types of energy, photon or charged particle. This damage is either direct or indirect ionization of the atoms which make up the DNA chain. Indirect ionization happens as a result of the ionization of water, forming free radicals, notably hydroxyl radicals, which then damage the DNA.

Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator.
When did ionizing radiation start?
The modern understanding of ionizing radiation got its start in 1895 with Wilhelm Röntgen. In the process of conducting various experiments in applying currents to different vacuum tubes, he discovered that, despite covering one in a screen to block light, there seemed to be rays penetrating through to react with a barium solution on a screen he’d placed nearby. After several experiments, including taking the first photo (of his wife’s hand and skeletal structure) with the new rays, he named them “X-Rays” temporarily as a designation of something unknown, and the name stuck.
Who discovered radioactivity?

Overview
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 and lesions produced by diseases such as lupus, basal cell carcinoma, and epithelioma. Radiation was generally believed to have ba…
Early development of radiotherapy (1895–1905)
The imaging properties of x-rays were discovered, their practical uses for research and diagnostics were immediately apparent, and soon their use spread in the medical field. X-rays were used to diagnose bone fractures, heart disease, and phthisis. Inventive procedures for different diagnostic purposes were created, such as filling digestive cavities with bismuth, which allowed them to be seen through tissue and bone.
Further development and the use of radium (1905–1915)
Because of the excitement over the new treatment, literature about the therapeutic effects of x-rays often exaggerated the propensity to cure different diseases. Reports of the fact that in some cases treatment worsened some of the patients' conditions were ignored in favor of hopeful optimism. Henry G. Piffard referred to these practitioners as "radiomaniacs" and "radiografters". It …
Commercialization, quackery, and the end of an era (1915–1935)
Widespread commercial exploitation of radium only began in 1913, by which time more efficient methods of extracting radium from pitchblende had been discovered and the mining of radium had taken off.

Medical uses
Different cancers respond to radiation therapy in different ways.
The response of a cancer to radiation is described by its radiosensitivity. Highly radiosensitive cancer cells are rapidly killed by modest doses of radiation. These include leukemias, most lymphomas and germ cell tumors. The majority of epithelial cancers are only moderately radiosensitive, and require a significantl…
Side effects
Radiation therapy is in itself painless. Many low-dose palliative treatments (for example, radiation therapy to bony metastases) cause minimal or no side effects, although short-term pain flare-up can be experienced in the days following treatment due to oedema compressing nerves in the treated area. Higher doses can cause varying side effects during treatment (acute side effe…

When Dupuytren's disease is at the nodules and cords stage or fingers are at a minimal deformation stage of less than 10 degrees, then radiation therapy is used to prevent further progress of the disease. Radiation therapy is also used post surgery in some cases to prevent the disea…
Technique
Radiation therapy works by damaging the DNA of cancerous cells. This DNA damage is caused by one of two types of energy, photon or charged particle. This damage is either direct or indirect ionization of the atoms which make up the DNA chain. Indirect ionization happens as a result of the ionization of water, forming free radicals, notably hydroxyl radicals, which then damage the DNA.
In photon therapy, most of the radiation effect is through free radicals. Cells have mechanisms f…
