About Magseed®
The Magseed® marker is a tiny magnetic seed made from stainless steel which is used to accurately mark tumors or lymph nodes, allowing surgeons to detect and remove them as precisely as possible during surgery.

The Magseed® marker is widely approved for long-term implantation to mark tumors in any soft tissue. Once placed, it cannot be dislodged or damaged and can be detected by the Sentimag® magnetic probe with incredible precision. This helps to overcome surgical scheduling pressures and drastically improve the patient experience.
It has been studied more than any other non-radioactive seed marker, with over 10,000 patients involved in Magseed® clinical trials. With over 250,000 Magseed® procedures carried out in operating rooms across the world, it is quickly becoming the new global standard in breast surgery.
About Magtrace®
The Magtrace® lymphatic tracer is the world’s first, non-radioactive dual tracer for lymphatic mapping in patients with breast cancer. Made from just four ingredients, iron oxide, sugar, salt and water, Magtrace® provides a simple solution for breast cancer staging. Designed specifically for sentinel lymph node biopsies, this magnetic liquid provides a more accurate and efficient way to locate and remove tissue. Its long injection window is also opening up opportunities for more advanced techniques.

Now used in over 1,000 centers in more than 45 countries, Magtrace® has helped over 100,000 breast cancer patients access the best standard of breast cancer care across the world. In addition to Maine Medical Center, this technology is also currently available at Southern MaineHealth and Lincoln Health.
According to Maine Medical Center breast surgeon Dr. Paige Teller, “We were early adopters of Magtrace in the New England region. Magtrace has afforded us the opportunity to perform delayed sentinel lymph node biopsy in our patient population where appropriate, potentially reducing the risk of lymphedema and invasiveness of care.”
