Stereotactic Biopsy

Your mammogram has shown an area of tissue that needs to be examined more closely. During this procedure, a needle is inserted into the breast and a small amount of tissue will be taken out for examination under a microscope. The images from the mammography machine are used to make sure that the samples are taken from the correct area.

What to expect
Local anaesthetic is used so that the area around the biopsy site will be numb. You will either lie down on the bed or sit on a chair during the procedure, which will take about one hour. You will be able to drive home afterwards but do not plan to do anything too energetic that day.

The results will take about one week to come back from the laboratory to the breast specialist.
