Breast Biopsies

Winneshiek Medical Center performs ultrasound-guided breast biopsies, stereotactic breast biopsies and surgical biopsies when a mammogram or MRI suggests further testing.

Ultrasound-Guided Breast Biopsies

An ultrasound-guided breast biopsy is an outpatient procedure that is performed by a radiologist. You are awake during this procedure. During an ultrasound-guided breast biopsy, you will be asked to lie on your back on an exam table, with your arm on the affected side raised above your head. The radiologist will inject local anesthesia into the affected breast, numbing the area for the procedure. Using an ultrasound probe to guide him or her, the radiologist will make a small incision (about 1/8 inch in length) to insert a special biopsy needle. The needle will remove a small amount of breast tissue; the radiologist will take several samples to ensure adequate sampling.

Following the procedure, the breast tissue samples will be evaluated by a pathologist and the results will be sent to your doctor. Your doctor will share the results with you and, together, you will determine the next steps of your care.

An ultrasound-guided breast biopsy takes between 30-60 minutes to complete.

Stereotactic Breast Biopsies

A stereotactic breast biopsy is an outpatient procedure that is performed by a radiologist who uses angled mammogram images to determine the exact location of the affected breast tissue. You are awake during this procedure. During a stereotactic breast biopsy, you will be asked to lie face down on a padded biopsy table. The breast to be biopsied will be positioned in a hole in the table during this procedure. The radiologist sits on a stool lateral to your breast to perform the biopsy.

The radiologist will inject local anesthesia into the affected breast, numbing the area for the procedure. Two compression plates will compress your breast and mammograms are taken to determine the exact location of the affected area. The radiologist will make a small incision (about 1/8 inch in length) to insert a special biopsy needle. The needle will remove a small amount of breast tissue; the radiologist will take several samples to ensure adequate sampling.

Following the procedure, the breast tissue samples will be evaluated by a pathologist and the results will be sent to your doctor. Your doctor will share the results with you and, together, you will determine the next steps of your care.

A stereotactic breast biopsy takes between 30-60 minutes to complete.

Surgical Biopsies

Surgical biopsies are performed by general surgeons at Winneshiek Medical Center. They are done as an outpatient procedure in the operating room.  Talk to your doctor to determine the right plan of care for you.
