What this trial studies

This study aims to evaluate the safety and effectiveness of the Magseed Pro® marker and Sentimag® Gen3 system for marking suspicious or biopsy-proven positive axillary lymph nodes and soft tissue lesions in the breast. The devices are intended to assist surgeons in accurately locating and excising targeted tissues during surgical procedures. This multicenter international study will involve participants who require localization of breast lesions or axillary nodes prior to surgical excision. Patients will have the Magseed Pro® marker placed to guide the surgical removal of the identified lesions.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who require localization of breast lesions or axillary lymph nodes for surgical excision.

Not a fit: Patients who are pregnant, nursing, or have certain medical conditions that may affect their ability to participate will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the precision of surgical excisions for breast cancer, potentially improving patient outcomes.

How similar studies have performed: Other studies using similar localization techniques have shown promise, indicating that this approach may be effective.
