Stereotactic biopsy refers to a needle biopsy using mammography to locate the area of concern and getting the sample with guidance under mammography. This procedure is done on "spots" that cannot be felt. A needle biopsy that is not done stereotactically, refers to a biopsy that is done with a needle.

What is stereotactic biopsy and what is the technique used?
A stereotactic biopsy is an innovative technique used most often to obtain a sample of a mass to see if it is cancerous. With this tissue sample, a pathologist can identify the grade and type of tumorfound. This operation is used in brain cancers to help facilitate a clear understanding of the tumor in the most minimally invasive way.

Why do I need a stereotactic biopsy?
A stereotactic breast biopsy is an option when a mammogram shows a breast abnormality such as: A suspicious solid mass. Microcalcifications — tiny clusters of small calcium deposits. A distortion in the structure of the breast tissue.
What is the best type of breast biopsy?

Should I worry about breast calcifications?

What is Stereotactic Biopsy?
Stereotactic biopsy is a kind of mammographically guided biopsy that uses x-ray to detect breast cancer or abnormality in breasts. In order to place the biopsy needle precisely at the correct location, stereotactic biopsy utilizes x radiation. Once placed, a small sample of tissue is removed for further examination in the laboratory.
What is Ultrasound Biopsy?
Ultrasound biopsy is an image-guided biopsy that uses ultrasound waves to place the biopsy needle precisely at the correct location. Therefore, ultrasound biopsy does not use radiation. Instead, it uses high-frequency sound.
What are the Similarities Between Stereotactic Biopsy and Ultrasound Biopsy?
In both stereotactic biopsy and ultrasound biopsy, a small sample of tissue is removed for further examination.
What is the Difference Between Stereotactic Biopsy and Ultrasound Biopsy?
Stereotactic biopsy uses an x-ray to examine and place the needle, while ultrasound biopsy uses ultrasound waves to place the biopsy needle. Thus, this is the key difference between stereotactic biopsy and ultrasound biopsy. Unlike stereotactic biopsy, ultrasound biopsy does not use ionizing radiation.
Summary – Stereotactic Biopsy vs Ultrasound Biopsy
Stereotactic biopsy and ultrasound biopsy are two relatively simple and less invasive biopsies than surgical biopsy. Stereotactic biopsy uses x radiation to guide the biopsy needle to the accurate location. In contrast, ultrasound biopsy uses sound waves to locate the biopsy needle to the accurate place.
