Abstract Accelerated partial breast irradiation is commonly done with the MammoSite applicator which requires symmetry to treat the patient. This paper describes three cases that were asymmetric when initially placed and became symmetric over time without manipulation. Background Accelerated partial breast irradiation APBI with the MammoSite catheter is a new brachytherapy concept in breast conserving therapy for a subset of patients with early stage breast cancer 1 2 .
