Magseed®

Meet the seed that changed the game

The original Magseed® is known worldwide as a simple and effective alternative to wire localization. So far, it’s been used in over 300,000 localizations — and counting.

So far. So good.

Magseed® was the first localization seed to be routinely used on all six continents that perform breast surgery.  It’s now the number one choice for thousands of physicians and used in more countries than any other localization seed.

Tried and tested

More than 10,000 patients have been involved in Magseed® clinical trials. That’s more than all the other seed devices combined.

Easier for patients

Magseed® helps remove some of the stress of breast cancer surgery. Patients can have their seed placed any time before surgery, when convenient for them, safe in the knowledge it won’t move before surgery.

Choose your approach

During surgery, the seed’s pinpoint signal allows the surgeon to take the most cosmetic approach to removing it. This reliable signal means the vast majority of patients are now having their cancer removed in one operation.

Why Magseed®?

The Magseed marker has been designed to simplify breast cancer treatment, from the time the cancer is marked, through to when it’s removed in surgery.

  • Accurate Placement

    With the choice of when and where to mark the cancer, you have ultimate control over placement.

  • Firmly Implanted

    The Magseed marker won't move, break, or deactivate — no matter when it's implanted.

  • Pinpoint Detection

    Detectable to the millimeter, Magseed will guide you to the tumor with absolute precision.

  • Accurate Removal

    Being certain of the cancer’s location means you can remove it while leaving behind as much healthy tissue as possible.

Magseed has simplified the whole process of the pre-operative localization for the surgery.

The advantage of seeds is that they can be placed anytime. That way, on the day of surgery you really just have to deal with the surgery schedule.
Dr. Abigail Caudle MD Anderson Cancer Center
Magseed has had a great positive effect on our department. There's easier coordination with our surgeons, with the operating room, and just scheduling our patients.
Dr. Heather Greenwood University of California San Francisco
I would highly recommend having the Magseed vs the wire. It's just so much better for the patient.
