In our study cohort the mastectomy rate did not differ (39 % vs. 39 %) between patients with and without preoperative breast MRI, although tumor stages and focality were higher in the group of patients undergoing MRI. Breast MRI was beneficial for 20.3 % (127/626) of the patients as additional foci of cancer in the same or contralateral breast were diagnosed (n=122) or MRI could prove a lesser extent of carcinoma (n=5). Patients receiving preoperative MRI had a lower chance of repeated surgery (p=0.007). Preoperative breast MRI did not delay surgery (20.3 days vs. 19.8 days, p=0.7).
