Breast biopsy

A biopsy takes a tiny sample of tissue so a pathologist can examine it under a microscope. It is the only way to know for certain whether a finding is cancer.

The word biopsy sounds alarming, but it is a routine, quick procedure done under local anaesthetic. Most biopsies confirm the finding is benign — and knowing for certain is always better than wondering.

Common types of breast biopsy

  • Fine needle aspiration: draws fluid or a few cells
  • Core needle biopsy: takes a small cylinder of tissue
  • Vacuum-assisted biopsy: collects a slightly larger sample
  • Surgical biopsy: rare, when a needle cannot reach the area

Ultrasound or mammography guides the needle so the sample comes from exactly the right place. A tiny marker may be left in the breast to identify the area on future imaging. Afterwards you will have a small bruise and minimal pain.
