WTEN: New Breast Cancer Research at SPHP Reveals More Success with Tumor Removal
November 3, 2026
Sarah Pesek, MD, breast surgeon with St. Peter's Breast Surgery, appeared on WTEN's Women's Health Wednesday segment, where she discussed the results of a clinical trial recently published in the Annals of Surgical Oncology.
Dr. Pesek was a principal investigator for the large, international trial that focused on new technology to make breast cancer surgery more precise and effective.
From the interview:
St. Peter’s Health Partners used the Breast Cancer Locator System on certain patients and found the new technology did a significantly better job in enabling surgeons to remove the complete tumor with no cancer left at the edge of the excision which reduced the need for follow up surgeries.
