Irradiation of node areas is still a complex challenge in external radiotherapy for breast cancer. Acceptable target coverage is always balanced by protection of organs at risk and patient morphology. Intensity-modulated radiotherapy increases the quality of dose distribution on the planning target volume, but modifies dramatically the irradiation coverage of critical structures in a different way compared to 3D treatment. In this paper we analyze this new technique in breast treatment with node regions, its expected gain and potential risks.
