Susan grew up in competitive swimming. In the late 70s, she was captain of the Syracuse University team. After graduating, Susan was diagnosed with a rare vaginal cancer—a hallmark of DES exposure in the womb. DES was the first synthetic form of estrogen and thought to prevent miscarriages. It was approved by the FDA without controlled studies, and beginning in the late 40s prescribed to 10 million women worldwide, including Susan’s mother. By the mid 50s, research revealed that DES didn’t work and was potentially toxic and carcinogenic. But it was a big money maker for over 275 U.S. drug companies, and it wasn’t until 1971 that it was removed from the market. But it was too late for 2 million DES daughters who were beginning to experience its devastating legacy.
