Area of Application:
The most common cancer among women

More than 1,676,000 women worldwide develop breast cancer every year. There is a growing demand for a thorough diagnosis of breast cancer, as well as improved and more patient-friendly products.

SchurSign® is both safe and precise in its application, making it well-suited for diagnosing tumors not only in the breast but also in other organs.

"The current markers with a metal core rarely meet the needs of my patients, especially when it comes to a permanent implant. Patients complain of discomfort and sometimes even pain. The ultrasound visibility of metal marker is often limited. Scars and capsule formation in particular make it difficult to see them on ultrasound. This makes intraoperative ultrasound imaging more difficult, which is standard practice for us. Occasionally, there is also migration from the insertion site, and gel-coated markers sometimes do not detach properly from the applicator, which carries the risk of incorrect placement.


I am happy to have supported SurgMark GmbH in its efforts to produce a patient- and user-friendly marker and to be able to continue to do so. I am fully convinced that SchurSign® will significantly improve the marking and thus the diagnosis and treatment of cancer in the future. Above all, I am impressed by the commitment and empathy of the SurgMark team, who have set themselves the goal of taking the future of medicine to a higher level with their products.”
