This chapter provides an overview of radiotherapy. Radiotherapy is the method of treatment using ionizing radiation. Normally, radiation is in the form of X-rays or gamma rays which, when directed through a cell, result in the ionization and destruction of DNA. Methods of delivering radiation include external X-ray beams and the use of radioisotopes. Radiation is potentially dangerous, hence administration of radiotherapy is usually done within a radiotherapy department. Radiotherapy plays a significant role in palliative care: it aids in the management of local symptoms such as pain, haemorrhage, and obstruction. Topics discussed in the chapter include the different kinds of radiation, radioisotope therapy, biological effects of radiation, and fractionation. The chapter also discusses the practicality of radiotherapy, and the practicality and efficiency of radiotherapy in palliative care.
