A letter from three University of Chicago researchers in this week’s New England Journal of Medicine updates a 47-year-old series of reports on the risks of exposure during pregnancy to a supplement, diethylstilbestrol (DES), that was once widely used but since 1971 has been linked to a rare cancer: clear-cell adenocarcinoma of the vagina and cervix. In the May 3, […]
