This study delivers radiation therapy to any residual breast tissue and the chest wall plus
lymph node areas around the breast. These lymph node areas are under the arm, around the
collar bone, and under the sternum (breastbone).
IMRT treatment uses a computer-controlled x-ray (CT) to deliver radiation beams at several
different angles and strengths to deliver precise doses to the regions at risk for recurrence
of breast cancer while reducing or sparing the dose to critical structures (heart, lungs) and
nearby normal tissue.
