Summary
Brief summary (as posted)
The purpose of this prospective observational study is to evaluate the impact of preoperative breast MRI in patients with breast cancer selected for breast- conserving surgery. MRI is a more sensitive radiological modality than mammography and ultrasonography. Patients with small breast cancers are, based on conventional modalities, selected for breast-conserving surgery. If preoperative breast MRI reveal additional lesions in the breasts, and malignancy is confirmed histopathologically, this finding leads to a change of surgical method to mastectomy.
