For nearly 40 years, Perez and Brady's Principles and Practice of Radiation Oncology has been the authoritative ‘book-of-record’ for the field of radiation oncology. Covering both the biological and physical science aspects of this complex field as well as site-specific information on the integrated, multidisciplinary management of patients with cancer, Perez & Brady continues to be the most comprehensive reference available for radiation oncologists and radiation oncology residents. Under the editorial leadership of Drs. Edward C. Halperin, David E. Wazer, and expert associate editors Drs. Brian C. Baumann, Rachel C. Blitzblau, and Natia Esiashvili, the fully revised 8th Edition, now known as Perez, Brady, Halperin, and Wazer’s Principles and Practice of Radiation Oncology, is available as a two-volume hardcover edition: Volume 1 covers The Scientific, Technological, Economic, and Ethical Basis of Radiation Oncology, while Volume 2 covers The Clinical Practice of Radiation Oncology.
