Please note that the content of this book primarily consists of

radiation oncologist is a doctor who specializes in the treatment
of cancer patients, using radiation therapy as the main modality of
treatment. 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. In some countries (not the United States),
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,
other surgeons, internal medicine subspecialists and medical
oncologists, as part of the multi-disciplinary cancer team.
