Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor. Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology. A physician who practices in this subspecialty is a radiation oncologist.
A radiation oncologist is a specialist physician who uses ionizing radiation in the treatment of cancer. Radiation oncology is one of the three primary specialties, the other two being surgical and medical oncology, involved in the treatment of cancer. Radiation can be given as a curative modality, either alone or in combination with surgery and/or chemotherapy. It may also be used palliatively, to relieve symptoms in patients with incurable cancers. A radiation oncologist may also use radiation to treat some benign diseases, including benign tumors. In some countries, radiotherapy and chemotherapy are controlled by a single oncologist who is a "clinical oncologist". Radiation oncologists work closely with other physicians such as surgical oncologists, interventional radiologists, internal medicine subspecialists, and medical oncologists, as well as medical physicists and technicians as part of the multi-disciplinary cancer team. Radiation oncologists undergo four years of oncology-specific training whereas oncologists who deliver chemotherapy have two years of additional training in cancer care during fellowship after internal medicine residency in the United States.
Brachytherapy is a form of radiation therapy where a sealed radiation source is placed inside or next to the area requiring treatment. Brachy is Greek for short. Brachytherapy is commonly used as an effective treatment for cervical, prostate, breast, esophageal and skin cancer and can also be used to treat tumours in many other body sites. Treatment results have demonstrated that the cancer-cure rates of brachytherapy are either comparable to surgery and external beam radiotherapy (EBRT) or are improved when used in combination with these techniques. Brachytherapy can be used alone or in combination with other therapies such as surgery, EBRT and chemotherapy.
In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer. The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy nearby tissues.
M. Krishnan Nair was an Indian oncologist. He was the founding director of the Regional Cancer Centre, Thiruvananthapuram, a director of the S.U.T. Institute of Oncology, and Trivandrum Cancer Center(TCC), part of SUT Royal Hospital in Thiruvananthapuram (Trivandrum) and a professor at the Amrita Institute of Medical Sciences & Research in Kochi. The Government of India awarded him the fourth highest civilian award of the Padma Shri, in 2001 for his contributions in the cancer care field.
The European Organisation for Research and Treatment of Cancer (EORTC) is a unique pan-European non-profit clinical cancer research organisation established in 1962 operating as an international association under Belgium law. It develops, conducts, coordinates and stimulates high-quality translational and clinical trial research to improve the survival and quality of life of cancer patients. This is achieved through the development of new drugs and other innovative approaches, and the testing of more effective therapeutic strategies, using currently approved drugs, surgery and/or radiotherapy in clinical trials conducted under the auspices of a vast network of clinical cancer researchers supported by 220 staff members based in Brussels. The EORTC has the expertise to conduct large and complex trials especially specific populations such as the older patient and rare tumours.
Fast neutron therapy utilizes high energy neutrons typically between 50 and 70 MeV to treat cancer. Most fast neutron therapy beams are produced by reactors, cyclotrons (d+Be) and linear accelerators. Neutron therapy is currently available in Germany, Russia, South Africa and the United States. In the United States, one treatment center is operational, in Seattle, Washington. The Seattle center uses a cyclotron which produces a proton beam impinging upon a beryllium target.

Neutron capture therapy (NCT) is a type of radiotherapy for treating locally invasive malignant tumors such as primary brain tumors, recurrent cancers of the head and neck region, and cutaneous and extracutaneous melanomas. It is a two-step process: first, the patient is injected with a tumor-localizing drug containing the stable isotope boron-10 (10B), which has a high propensity to capture low energy "thermal" neutrons. The neutron cross section of 10B is 1,000 times more than that of other elements, such as nitrogen, hydrogen, or oxygen, that occur in tissue. In the second step, the patient is radiated with epithermal neutrons, the sources of which in the past have been nuclear reactors and now are accelerators that produce higher energy epithermal neutrons. After losing energy as they penetrate tissue, the resultant low energy "thermal" neutrons are captured by the 10B atoms. The resulting decay reaction yields high-energy alpha particles that kill the cancer cells that have taken up enough 10B.

Docrates Cancer Center is the first and currently the only private hospital in the Nordic countries that comprehensively specialises in cancer treatment. It operates in Helsinki, Finland. It characterises its operations as those complementing the public sector. Docrates Oy was established in 2006 and the hospital started its operations at the premises of Eira Hospital in autumn 2007. It moved to its own premises in Jätkäsaari, Helsinki, in 2009, where it has hospital rights. There is a ward and Health and Recovery Center located at Docrates Cancer Center. Among other things, diagnostics, pharmacotherapy, radiation therapy and isotopic treatments are carried out at the hospital. Cancer surgeries are performed in partner hospitals. Docrates also participates in clinical trials and the testing and development of new treatments.
