The most popular kind of radiation therapy administered inside is called brachytherapy. It is used to treat various cancers, such as breast, cervical, prostate, uterine, and vaginal cancer. Brachytherapy is primarily administered by radiation oncologists, just like external beam radiation therapy (EBRT). It depends on the hospital how you receive brachytherapy.
Brachytherapy involves putting sealed radioactive sources inside the body, either near or inside the tumour. The sources emit gamma rays, which work over a very small area yet have the same impact on cancer as the x-rays used in external beam radiation therapy (EBRT). It is a method of providing the cancer a high dose of radiation while only allowing a very small dose to reach the nearby tissues and organs. The type of cancer being treated determines the type of brachytherapy employed. It could include of pellets, seeds, needles, wires, or other small, mobile sources that are applied to the body through applicators from a machine (thin plastic tubes). Both brachytherapy and EBRT are options.
