Radiation oncology is a modality of treatment that involves the controlled use of radiation beams to treat cancer and other symptoms caused by cancer. Radiation therapy also known as radiotherapy is the term used to describe the actual treatment delivered by the radiation oncology team.
Radiation therapy can be delivered to treat a wide range of cancers, and may be used alone or in conjunction with surgery, chemotherapy and other treatments. Radiation Therapy is usually completely non-invasive, and does not require a patient to be admitted for the treatment.
Radiation Oncology includes responsibility for the diagnosis, treatment, follow-up and supportive care of the cancer patient, and forms an integral part of the multidisciplinary management and investigations of patients.
