This is a two-arm randomized clinical trial with one test group (communication of the QL-finding to the coordinating physician) and a control group (no communication). Patients with newly diagnosed breast cancer who are treated in the study region by one of the coordinating doctors will be included in this randomized study. QL-assessments (EORTC QLQ-C30 plus BR23) will be taken at designated points in time over a 12 months time course. Finally, patients will provide an overall evaluation of the course and the effects of the therapy using an open-ended questionnaire.
