This breast procedure is needed to clearly show which part of the breast tissue needs to be removed during your operation.

What to expect
The skin around the area is cleaned with a sterilising solution, then numbed with a local anaesthetic. A fine needle is then inserted into that area and the mammography machine is used to take films to check the position of the needle. Your breast will not be flattened as much as during a normal mammogram. A very fine wire with a hook on the end follows the length of the needle and remains in the breast until you have your operation.
