29^th International Oncology Summit

Radiation oncology

Each radiation oncologist has specialized training in performing radiation treatment for people with cancer and those with certain noncancerous (benign) conditions. The doctors further specialize by concentrating their individual practices on treating different types of cancers, including complex and rare cancers. Radiation oncology (radiotherapy/radiation therapy) is a medical speciality that is an essential part of a multidisciplinary approach to cancer treatment. It uses high energy x rays(photons) most commonly delivered through a linear accelerator. A radiation oncologist may use external beam radiation therapy or brachytherapy to treat cancer. External beam radiation therapy can be generated by a linear accelerator (a machine that accelerates electrons to produce x-rays or gamma rays).
