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).
