Stereotactic Guided Biopsy

Stereotactic mammography is a procedure used to pinpoint the exact location of a breast abnormality. This is done by using a computer analysis of X-rays taken from two different angles. Using calculated computer coordinates, the radiologist inserts a needle through a small cut in the skin, and then advances it into the lesion and removes tissue samples.

A stereotactic guided biopsy is performed so that a sample of breast tissue can be taken from the breast of an abnormality that is visible on a mammogram, but not on a breast ultrasound examination.

The purpose of a stereotactic guided biopsy

Stereotactic breast biopsies will help determine whether you have breast cancer or any other abnormalities. A stereotactic mammography may be performed when a mammogram shows a breast abnormality, such as:

  • A new mass.
  • A suspicious mass.
  • An area of abnormal tissue change.
  • Distortion in the structure of breast tissue.
  • Microcalcifications (tiny clusters of small calcium deposits).
