The incidence of ductal breast carcinoma in situ (DCIS) is increasing and currently lies at about 15% of all breast cancers. Detection of DCIS reduces the subsequent incidence of invasive ductal carcinoma. Patients with Breast Imaging Reporting and Data System (BI-RADS) category 4 lesions are best served by minimally invasive biopsies to improve the precision of diagnosing DCIS lesions. Vacuum-assisted biopsies have the greatest sensitivity and specificity of the biopsy techniques and reduce tumor upgrading of DCIS lesions at operation by at least half compared with core-needle biopsy. Moreover, vacuum-assisted biopsies have proved to be safe and reduce health care costs. Since they provide a maximum of preoperative information, vacuum-assisted biopsies could improve outcomes in patients with DCIS.
