About this trial
Partial Breast Irradiation (PBI) is a targeted radiation approach commonly administered post-lumpectomy, specifically targeting the tumour bed. This targeted therapy reduces the exposure to other nearby tissues such as lungs, heart, and chest wall. However, traditional PBI treatment involves lengthy multiple fraction courses which presents a burden to patients from rural and remote communities, who must travel long distances to receive high quality cancer care. The purpose of this study is to compare single fraction (SF) PBI vs. multiple fraction (MF) PBI.
