This is a randomized phase II trial comparing participants with stage II-III breast cancer treated with accelerated Proton Beam Radiation Therapy (PBT) versus accelerated conventional photon radiation therapy (XRT) inclusive of the regional lymph nodes.
Participants will be randomized into one of two study groups: proton beam radiation therapy versus photon radiation therapy. Randomization means that participants are put into a group by chance.
Study procedures includes screening for eligibility, study treatment visits, Cardiac Magnetic Resonance Imaging (MRI), blood tests, and questionnaires.
The National Cancer Institute, American Society of Clinical Oncology, and Claflin Grant are supporting this research by providing funding for the research study.
