This number was announced by Dr. Barbieri, Harvard Professor and Chief of Obstetrics and Gynecology at the Brigham and Women's Hospital in Boston, in article by the Boston Globe and the Wall Street Journal. The analysis that led to this discovery comes from a group of 4 physicians: One from Boston University and three from the Brigham and Women's Hospital. The manuscript is currently under review at the New England Journal of Medicine, along with another demonstrating a similar result. A 1 in 400 risk of spreading cancer to a stage 4 with morcellation, is medically unacceptable and floridly unethical. Help us stop this deadly gynecological "standard of practice".
