Breast Biopsies

A biopsy is carried out when your doctor has determined that a biopsy of the breast will be useful for diagnosis. The procedure will be explained by the sonographer. It will take approximately 30 – 45 minutes once you are in the ultrasound room.

The skin will be cleansed and the biopsy site numbed with a local anesthetic. There are two types of biopsy procedures: a fine-needle aspiration and a core biopsy. These vary in the type of needles used. Both procedures are guided by ultrasound. The type of biopsy and number of samples taken will depend on your specific case. Please see the Ultrasound Preparation page for more information.
