Overview
Radiation oncologists design and deliver targeted radiation treatments to control tumors and relieve symptoms while minimizing normal tissue toxicity. Techniques include external beam radiotherapy brachytherapy and stereotactic approaches. Multidisciplinary coordination with surgery and medical oncology optimizes combined modality care.
Clinical Practice
Care includes simulation and treatment planning, fractionation selection and management of acute and late radiation effects and integration with systemic therapies. Radiation oncologists participate in tumor boards and survivorship planning. Precision planning and image guidance improve therapeutic ratios.
Procedures and Tools
Tools include CT MRI and PET for planning, treatment planning systems, linear accelerators and brachytherapy suites and dosimetry services. Quality assurance and physics oversight ensure safe dose delivery. Advanced techniques such as IMRT and proton therapy expand treatment options.
Training and Roles
Radiation oncologists complete residency training and often pursue fellowships in subspecialty areas and maintain board certification. They collaborate closely with medical physicists, dosimetrists and radiation therapists to deliver complex treatments. Research in radiobiology and technology drives innovation.
