Types of radiation therapy

In radiation therapy, a distinction is made between teletherapy (external beam radiation therapy) and brachytherapy.

Ionising radiation Brachytherapy

In brachytherapy (Greek brachys - short, close) the radiation source is placed in immediate proximity to or directly into the area to be irradiated. As contrasted with teletherapy, brachytherapy allows radiation treatment from inside.

Ionising radiation Teletherapy

In teletherapy (Greek tele: far), the radiation source is located at a spatial distance from the tumour. In the process, mostly tumours inside the body are irradiated through the skin from outside the patient. This case is referred to as percutaneous radiation therapy (percutaneous - through the skin). Various radiation qualities can be used.
