About this study

The goal of this study is to investigate the differences in toxicity and efficacy between proton and photon hypofractionated radiotherapy following lumpectomy or mastectomy for breast cancer. The main questions it aims to answer are: 1. What is the difference in the incidence of radiation-related grade 2 or higher adverse events within two years following proton versus photon therapy after breast-conserving surgery? 2. What is the difference in the incidence of radiation-related grade 2 or higher adverse events within two years following proton versus photon therapy after mastectomy?
