Wire Marking (Wire) Biopsy

How is Needle Localization Biopsy (with wire) Performed?

Needle localization biopsy is important in finding the tumor area in the breast. The needle localization biopsy (with wire) is performed on the same day as surgery. The steps of this procedure are as follows:

• First, local anesthesia is applied to the patient.
• A needle containing a thin wire is placed into the suspicious area in the breast using imaging techniques.
• After placing the wire in the suspicious area, the needle is withdrawn.
• A part of the wire is left inside the breast while the other part remains outside.
• The outside portion of the wire is taped to the breast.
• A film is taken to check the position of the wire.
• After these steps, the patient is taken to surgery.
• Since the end of the wire is hook-shaped, no displacement occurs.
• During surgery, the surgeon locates the wire.
• The surgeon removes the tissue around the wire.

Thus, the procedure is completed.

What is the Roll Localization Method?

The Roll localization method is a method that uses radioactive material to mark the cancerous area instead of using a wire. In this procedure, local anesthesia is applied to the patient. A needle is placed into the suspicious area. A radioactive substance is injected through the tip of the inserted needle. Then, a contrast agent is injected from the same needle. A film is taken to understand where the marking is located. During surgery, a gamma probe is used. This device is moved over the breast, and once the substance is detected, it alerts the surgeon, allowing the marked area to be found.

What Are the Advantages of Needle Localization Biopsy (with wire)?

The advantages of wire biopsy can be listed as follows:

• Helps to accurately locate areas identified in imaging techniques but not detectable on physical examination during surgery.
• No significant volume loss in the breast.
• Prevents shape distortions and imbalances.
• Reduces the chance of leaving small tumors after surgery.

What Are the Disadvantages of Needle Localization Biopsy (with wire)?

The disadvantages of needle localization biopsy can be listed as follows:

• The end of the wire remaining outside the breast.
• The patient may feel discomfort due to the protruding wire end.
• The wire may not be positioned exactly above the tumor.
• The wire may be cut along with the tumor during removal.
• The wire may remain inside the breast.

Use of Ultrasonography in Needle Localization Biopsy (with wire)

By marking the lesion with a wire under ultrasonography or magnetic resonance guidance, the location of the mass is determined. The lesion is then removed in the operating room under wire guidance. After the lesion is removed, ultrasonography or magnetic resonance is used to confirm that the lesion has been completely excised, and the surgery is concluded. If any tissue remains, it is removed as well. This ensures that sufficient tissue is sampled while avoiding unnecessary removal of breast tissue.

What Is the Difference in Needle Localization Biopsy (with wire)?

It is a procedure that can be performed instantly without the need for general anesthesia. It may be slightly more expensive than fine or coarse needle methods, but better results are achieved through ultrasound imaging. The procedure involves more equipment and materials, making it more costly than other biopsy methods. However, this procedure ensures that the necessary tissue is completely removed without leaving any small tumor tissues behind, thus eliminating the need for a second surgery.
