What is a lumpectomy?
Nonpalpable lesions are usually discovered on routine screening mammography or on diagnostic workup using breast
ultrasound or breast MRI. Microcalcifications, masses, densities, and architectural distortion fall into the category
of potentially malignant lesions. Breast ultrasound can identify complex cystic or solid masses, and MRI can show
areas of abnormal vascular enhancement. In these instances, the breast usually feels and looks normal. Typically, the
radiologist places one or more percutaneous hookwires in close proximity to the lesion, using local anesthesia. Later,
in the operating room, the surgeon then uses the hookwire(s) as an anatomical guide to locate and excise the area of
abnormality. These procedures are referred to as wire-localization breast biopsies or lumpectomies. In the OR,
the surgeon removes the breast tissue surrounding the wire and confirms the removal of the wire and target lesion
on specimen radiography and/or ultrasound. Bracket wire localization refers to placement of multiple hookwires
to mark the periphery of a larger lesion or multiple lesions so tissue can be removed between the bracketing wires
