Minimal Invasive Breast Cancer Excision Using Vacuum Assisted Biopsy Under Ultrasound Guidance

First, the tumor will be removed under local anesthesia using the VAB system with US guidance, through a small skin incision (\<0.5 cm). A localization marker will be placed in the biopsy cavity, to help determine the cavity location.

After 3 weeks, the breast conserving surgery is performed, excising the VAB excision cavity and a ≥1 cm of surrounding tissue, as deemed appropriate by the attending breast surgeon. A sentinel node biopsy will be performed in the same procedure.
