Overview
- The findings were published in JAMA Network Open on February 2, 2026 by a University of British Columbia–led team.
- Researchers analyzed health records for more than 85,000 people in British Columbia who had gynecologic surgery between 2008 and 2020, comparing those with and without the added procedure.
- The analysis found a 78% lower incidence of serous ovarian cancer after the procedure, with rare post-procedure cancers appearing less biologically aggressive.
- Results were supported by data from international pathology laboratories, and prior studies indicate the approach is safe, hormone-sparing, and cost-effective.
- British Columbia reports uptake in roughly 80% of hysterectomies and tubal ligations, professional bodies in 24 countries recommend the strategy, and the province is piloting use in general and urologic surgeries.
