[Radiotherapy of benign disorders]

The radiation oncologist's primary concern is treatment of patients with malignant tumors but sometimes faces on occasion rare, non malignant disorders. The scarcity of disease incidence is reflected by the paucity of references for these diseases in the literature. This minimal exchange of information may make research and analysis difficult, tedious and not easily directed. Even with recognition of the risks of late skin injury, carcinogenesis, leukemogenesis and genetic damage from all ionizing radiation, radiation therapy also continues to be accepted treatment for benign diseases that do not respond to other methods of therapy. The purpose of this paper is to provide a short overview of the radiotherapy of most frequent benign disorders.
