Brachytherapy is a method used to raise local control of the disorder by increasing the dose of radiation applied to the tumor before and after external radiotherapy. However, it may also be used on its own for curative purposes in patients whose situation is suitable for such treatment.
In brachytherapy, radioactive sources are placed in the tumor and target tissues with unique methods; thus, limitation of dose around sources is provided.

Fields of application for radiotherapy
It is possible to separate radiotherapy in two main groups depending on the state of the disease:
In the light of the available information about the disease, it is applied in cases where the disease can be completely treated. It can be applied alone or with surgery and/or chemotherapy.
Applied in cases where it is impossible to completely destroy the disease. The goal is to prevent and relieve suffering and to improve quality of life for people facing serious, complex illness. For instance, bone pain suffered by a patient can be reduced by radiotherapy. Blood loss can be brought under control with radiotherapy applied on hemorrhagic tumors. The radiation dose given in this type of radiotherapy is lesser than the dose given in curative radiotherapy. The treatment duration is also shorter.
