That was a study we did that looked at hysterectomies and tubal sterilizations across Canada. What we found was that between 2017 and 2020, 80,000 Canadians received a tubal ligation or a hysterectomy without a salpingectomy, so they missed the opportunity to have their Fallopian tubes removed. This is well into the time when we were recommending opportunistic salpingectomy: The SOGC formally recommended it in 2015. That will translate into a possible thousand future cases of ovarian cancer that could have been prevented if that opportunity had been taken to remove those Fallopian tubes.
