Brachytherapy is a form of radiation therapy in which a sealed radioactive source is placed directly inside or next to the tissue requiring treatment, most commonly a tumor, allowing a high radiation dose to be delivered locally while sparing surrounding healthy tissue. Its name derives from the Greek brachys, meaning short-distance. The technique traces to 1901, when physicist Pierre Curie suggested to physician Henri-Alexandre Danlos that a radioactive source could be inserted directly into a tumor, and it has since become a standard treatment for cancers including those of the cervix, prostate, and breast.

How is brachytherapy different from external beam radiation therapy?
Brachytherapy places the radiation source at the tumour instead of aiming a beam from outside the body.
In external beam radiation therapy, high-energy x-rays are directed at the tumour from outside the body. Brachytherapy instead places short-range radiation sources, such as iodine-125 or caesium-131, directly at the site of the tumour.
