A new standard in
breast cancer staging.

Perform radiation-free sentinel lymph node biopsies

The tiny magnetic particles of the Magtrace® lymphatic tracer are optimized to take the same path a spreading cancer cell would through the lymphatic system, making it an ideal tracer for sentinel lymph node biopsy procedures.

Why use Magtrace?

Flexible. Accurate.

Magtrace® lymphatic tracer for sentinel node mapping

The Magtrace® lymphatic tracer is a liquid tracer that has been developed specifically for sentinel node biopsies. Detected by our Sentimag® localization system, this non-radioactive tracer directs surgeons to the first draining lymph nodes most likely to contain cancer to help determine if it has spread.

This simple liquid allows any patient or any hospital to access the highest standard in breast cancer staging.
