Vacuum-assisted breast biopsy (VABB) is a minimally invasive, image-guided procedure used to collect breast tissue samples for laboratory examination. It uses a specialised needle and gentle vacuum suction to obtain tissue through a small skin incision. Imaging guidance, such as ultrasound or mammography, helps the clinician target the area of concern.
VABB may be recommended to investigate certain breast lumps, suspicious imaging findings, or other breast abnormalities. It can sometimes be used to remove selected benign breast lesions, depending on their size, location, imaging features, and the clinician’s assessment.
Although VABB generally requires only a small incision, it may leave a small mark and can cause bruising, swelling, discomfort, or bleeding. The appropriate procedure depends on the individual breast finding and the need for an accurate diagnosis.
A breast biopsy may be recommended when a clinical examination or breast imaging identifies an abnormality that requires further investigation. The decision depends on the characteristics of the finding, the imaging results, and the patient’s medical history.
Compared with open surgical biopsy, VABB can provide a less invasive way to obtain tissue samples in suitable cases. However, it is not appropriate for every breast abnormality, and some patients may still require surgical biopsy or additional treatment.
Vacuum-assisted breast biopsy may be considered in selected cases, including:
Breast lumps: To obtain tissue samples from a lump that requires further assessment.
Fibroadenomas: To sample or, in selected cases, remove certain confirmed or appropriately assessed benign fibroadenomas.
Multiple or recurrent fibroadenomas: When the clinician determines that tissue sampling or removal is appropriate.
Imaging-detected abnormalities: To investigate certain findings identified during breast ultrasound or mammography.
Selected symptomatic benign lesions: When removal is considered appropriate after clinical and imaging assessment.
The choice of VABB depends on factors such as the size and location of the lesion, imaging findings, previous biopsy results, and the patient’s preferences. Not every benign breast lump needs removal, and VABB does not replace follow-up imaging or further treatment when these are indicated.
Patients should discuss the benefits, limitations, possible complications, and alternative procedures with their treating clinician before deciding on a biopsy.
