Diagnostic Evaluation

What is a Vacuum-Assisted Biopsy?

A vacuum-assisted biopsy is a minimally invasive procedure used to obtain tissue samples from the breast when more detailed evaluation is needed.

It is particularly useful in specific situations, such as:
* Diffuse or subtle abnormalities seen on imaging, like clusters of microcalcifications or architectural distortion
* Cases where a previous core needle biopsy was non-diagnostic or inconclusive.

This technique allows for accurate sampling through a single small incision and may, in certain cases, provide a more representative sample of the area
under investigation.

What To Expect?

Vacuum-Assisted Biopsy

Step 1

You will be positioned comfortably. The area of concern is cleaned and numbed using local anaesthetic. You will remain awake, and general anaesthesia is not required.

Step 2

Guidance by ultrasound or mammography is used to precisely locate the area. A small probe is inserted through the skin into the targeted tissue.

Step 3

Using gentle vacuum suction, multiple tissue samples are collected. In some cases, the abnormality may be fully removed during the process.

Step 4

The procedure is completed in less than an hour. A dressing is applied over the site, and you will receive aftercare instructions. Most individuals can return
to light activities within 24 hours.

 Is a Vacuum-Assisted Biopsy Painful?

Local anaesthetic is used to numb the area, and the procedure is generally well tolerated. Some people describe a sensation of pressure, but significant discomfort is uncommon.

How long does the VAB procedure take?

Vacuum-assisted biopsy typically takes 20 to 40 minutes, depending on the size and complexity of the area being sampled. It is performed on an
outpatient basis.

What happens after the biopsy?

A small dressing is applied. Mild bruising or swelling may occur, but usually resolves within a few days. The tissue samples are analysed, and your referring doctor will follow up with the results, typically within a week.
