Comparing Vacuum-Assisted Percutaneous Excision to Open Surgical Excision for Borderline or High-Risk Breast Lesions

The intervention group will undergo the vacuum assisted percutaneous excision (VAPE). All VAPE procedures will be performed on a digital supine table using the ATEC© Breast Biopsy System hand piece (Hologic) with a 9-gauge needle and a 10 or 20 mm aperture providing 6-mmHg of suction strength to completely excise the breast lesion.

The control group will undergo standard open surgical excision of the breast lesion. This will be done in the operating room using preoperative image-guided localization with radioactive seed (I-125) or in the procedure room of the Breast Care Centre if appropriate (i.e. lesion is palpable and localization is not required).
