What is a breast biopsy and when is it usually required?

A breast biopsy is a test that is performed if there are changes in your breast tissue that may raise suspicion of cancer. During the procedure, a small sample of tissue is taken.

  • Core needle: a large needle is inserted into the lump and small tissue samples are removed.
  • Open: in this case, a surgical cut is made in the breast to be studied in order to extract a small sample.
  • Stereotactic: performed with the aid of a computer to find the site of the lump and take the sample from the correct place.
  • Vacuum-assisted central vacuum: an ultrasound or X-ray-guided probe is inserted. A device is inserted through the probe to cut and collect small tissue samples.
