What is a breast biopsy used for?

A breast biopsy is performed to investigate areas that have been identified during imaging or clinical examination, such as:

  • A breast lump
  • An abnormality seen on ultrasound or mammography
  • Areas of thickening or concern

The tissue sample is sent for analysis to help determine the nature of the finding.
