Endomag for Patients

This guide has been written to help you understand more about what's involved in a lumpectomy performed using the Magseed® marker, if you've been diagnosed with early-stage breast cancer.

A sentinel lymph node biopsy (SLNB), is a treatment that takes place alongside the removal of a cancerous lump from your breast. It involves identifying and then surgically removing a small selection of sentinel lymph nodes from your underarm, before analysing them to see if your cancer has spread beyond the initial lump.

Targeted axillary dissection (TAD) is a treatment that involves ‘marking’ cancerous lymph nodes in your underarm early, before undergoing a therapy such as chemotherapy. This is done ahead of surgery to attempt to eliminate or shrink the cancer in the lymph node, before later removing the lymph nodes in surgery for analysis.

For most patients with ductal carcinoma in situ (DCIS), a SLNB procedure at the same time as your planned breast surgery is common. Fortunately, thanks to our Magtrace® tracer, a new 'delayed' sentinel lymph node biopsy is possible, providing up to 80% of DCIS patients the opportunity to potentially avoid lymph node surgery altogether.
