Radiation Therapy is an important cancer treatment that uses controlled doses of ionising radiation to damage the DNA of cancer cells and prevent them from growing or dividing. It can be delivered to many types of cancer and may be used with curative or palliative intent. Treatment planning typically involves CT or other imaging to define the tumor and surrounding organs at risk. Techniques such as IMRT, IGRT, stereotactic radiation, and brachytherapy may be selected according to the patient's condition.
