Magseed Procedures
A Magseed marker is a small magnetic, unbreakable seed that is placed into patients to help guide surgeons during a breast lumpectomy for impalpable breast cancer.
Made of sterile surgical-grade steel, the Magseed is extremely small – smaller than a grain of rice. It is inserted using ultrasound or X-ray guidance before surgery to help guide breast surgeons during breast surgery.
During surgery, the surgeon will use a handheld Sentimag to locate the Magseed from the surface of the skin. Once the location of the Magseed has been located next to the cancer, the surgeon will then plan the incision and operate accordingly.
