Radiation therapy is a personalized treatment for every patient
Different radiation therapy types
Radiation therapy is a personalized therapy and depends on various factors such as the type tumor, its location, the radiation treatment duration and the type of therapy. Different radiation therapy types can be distinguished: internal, external and so called metabolic radiation therapy. When radiation beams are delivered by a machine outside the body, it is called external radiation therapy. The beams will go through the skin before reaching the tumor. If the source of radiation therapy is placed inside the body, close to the cancer cells, it is called internal radiation therapy or brachytherapy. Metabolic radiotherapy involves a radioactive device, given orally (through drink or capsule) or injected intravenously. Once swallowed or injected the device attaches itself to the cancer cells to destroy them.
