This is a companion study to the "Pragmatic Randomized Trial of Proton vs Photon Therapy for Patients with non-Metastatic Breast Cancer Receiving Comprehensive Nodal Radiation: A Radiotherapy Comparative Effectiveness (RadComp) Consortium Trial" (NCT02603341). The investigators will collect cardiovascular (CV) biomarkers and echocardiograms prior to, during, and for up to 1 year following radiation for a subset of patients enrolled on RadComp and to evaluate the impact of proton vs photon radiation therapy (RT) on CV function and structure.
