title: [Radiotherapy of cancer of the breast. Technical problems and new approaches].
abstract: Technical problems often arise during irradiation to the breast, chest wall, and regional lymph nodes. The following are among the most frequently encountered problems: avoidance of normal tissues (heart and lungs) during chest wall, internal mammary nodes, and large breast irradiations; dose heterogeneity in large breasts; under- or overdosage at field junctions (breast medial tangent and internal mammary fields in particular). Various technical solutions have been offered: modified treatment positions, field inclinations, and conformal irradiation. Many are currently under evaluation. These new technical approaches in breast cancer irradiation require modern facilities for imaging, simulation, and dosimetry, which help to individually design treatment planning.
