Breast cancer is the most frequent cancer of women in the western hemisphere. This book presents a new imaging modality of the breast which improves the possibilities of mammography at a very high level: Cancers can be detected at a very early stage y MRM. The huge number ofbreast biopsies can be reduced dramatically. Even tiny breast cancers (e.g.3mm) can be detected. The prognosis for women with breast cancer will improve due to earlier detection.
