Additional Study Information: This study is being done to answer the following question: How can we best help patients and their clinicians make decisions about breast cancer treatment (surgery and other treatments, like radiation and chemotherapy)? We are doing this study because we want to better understand how to support patients in making decisions about breast cancer treatment. We want to see if new approaches to support patient decision-making and patient-clinician communication about breast cancer treatment are better than existing or usual approaches. We are testing two interventions, one for patients and one for clinicians.
