Preparing for Your Breast Biopsy
Why a Breast Biopsy is Performed
A breast biopsy is performed when a mammogram, ultrasound or physical examination has found a lump, abnormality, or suspicious microcalcifications. This procedure involves taking sample tissue from the suspicious area. A biopsy allows a pathologist to examine the abnormal tissue under a microscope to determine what it is and whether it could possibly be cancerous.
Breast Biopsy Methods
Several factors determine which biopsy method should be used, including the location and size of the area in question. We provide the following types of breast biopsies:
Ultrasound Guided Breast Biopsy
This method uses ultrasound to locate the abnormality and to provide precision and guidance while obtaining the samples. Once located, the area is numbed, and a small incision is made so an instrument can be gently inserted to obtain tissue samples for the pathologist to review.

Stereotactic Needle Biopsy
A stereotactic biopsy uses mammography and computer plotting to identify the breast abnormality. This method is frequently selected to sample microcalcifications of concern. The patient lies on her stomach with the breast fitted through a hole in the table. The breast is numbed, and a small incision is made. The instrument obtains numerous samples, which are sent to the pathologist for review.

MRI Guided Breast Biopsy
An MRI guided breast biopsy is used when MR imaging reveals a breast abnormality, such as a suspicious mass unidentified by other surgical techniques, an area of distortion, or an area of abnormal tissue change. The biopsy is typically performed within a closed MRI system with a specially modified table where breasts hang freely from cushioned openings. MR imaging is used to assist in guiding the radiologist's instruments to the site of abnormal growth. MRI guided breast biopsy is offered at MyMichigan Medical Centers in Midland and Alma.
