Core Biopsy

Core Biopsy

Sometimes an area identified on mammography films, is considered to be of concern, and may need to be biopsied. Alternatively it may be an area that can be felt during breast examination and is visible using ultrasound.

A core biopsy of an area can be performed by a Radiologist using Ultrasound to guide the needle to the correct position. The biopsy involves taking a fine sliver of tissue to be taken for pathological analysis. As with all biopsy type procedures being on Warfarin is a relative contra-indication to the procedure.

Local anesthetic is injected into the skin and a biopsy needle is inserted into the area. It is usual to take several samples to ensure that a representative sample has been obtained from the area of concern.

The procedure takes approximately 30-45 minutes and is generally well tolerated by most women. There may be some bruising as a result of the procedure but mild painkillers and application of ice can help with that.

After the procedure the tissue samples are sent to the Pathology Laboratory for analysis. The results are sent to the person that requested the biopsy and is co-ordinating your care.
