Ultrasound Guided Core Biopsy
Your breast ultrasound 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 ultrasound machine is used to show the exact location of the area to be sampled.
What to expect
Local anaesthetic is used so that the area around the biopsy site will be numb. You will lie down on the bed during the procedure, which will take about 45 minutes. 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.
