Technique of locoregional irradiation in breast cancer.

In medicine, one modality of treatment cannot be replaced by another unless the new method is equal, if not superior, to the existing one. Currently, much is heard about using irradiation alone for the treatment of early breast cancer. Uniform irradiation of the breast, underlying chest wall, and the regional lymph nodes is a complex procedure and unless done properly, a geographical miss of the tumor and/or unnecessary irradiation of adjacent normal structures can occur, leading to inferiority of the treatment method.
