3. Advantages and disadvantages of the technique
Advantages:Positioning the wire needle helps the surgeon to remove the abnormal breast mass that is not palpable. This method helps to mark even the smallest lesions identified by MRI, ultrasound or mammography. Because only the localized lesion is removed, the surgical scar is very small and the breast shape is maximally preserved. This method also helps to reduce surgery time, especially when you are anaesthetized with general anesthesia.
Short hospital stay only about 1 day.
Cons:
Some women experience an allergic reaction to local anesthetics, although this is rare. When it comes to MRI imaging, there are some problems if you have a previous metal implant in your body. In rare cases, you may be allergic to the contrast agent used in an MRI scan. Thread breakage also occurs occasionally. However, this is rarely dangerous, because the loop material is similar to the positioning clips the doctor places in the mammary gland, so there is no need to remove it if a needle is missing. Displacement of the wire needle: due to the loose fatty tissue of the mammary gland and the weak hook of the needle, you need to keep the loop fixed and avoid strong movement after the needle is positioned. When the needle is displaced you will need to place it to reposition the breast lesion again.
