The Added Value of Contrast Enhanced Mammography to Standard Mammography in Assessing the Extent of DCIS

The study hypothesis is that the rate of inadequate surgical margins after conservative breast surgery for DICS and the rate of reoperation (re-excision or/and mastectomy) is lower in the group of patients who underwent standard preoperative mammography and CEM to assess the extent of DICS, compared to the group of patients for whom the preoperative assessment of the extent of in situ breast cancer was not performed using one of the imaging techniques with contrast medium such as contrast mammography or magnetic resonance imaging.
