Study Summary

In the setting of radiotherapy as part of breast-conservation therapy for patients with early stage breast cancer, the novel planning and delivery method of intensity modulated radiotherapy is an effective and safe alternative to the commonly-used standard 3D-conformal external beam radiotherapy, spares more normal breast and lung tissue, and may lead to improved clinical outcomes.
