Women Exposed to Synthetic Estrogen Diethylstilbestrol (DES) in the Womb Face Increased Cancer Risk, Study Finds
In the late 1960s, an unusual occurrence of a rare cancer of the vagina among young women, called clear cell adenocarcinoma (CCA), was observed and subsequently linked to their exposure to DES while in the womb.

Increased risks of clear cell adenocarcinoma of the vagina and cervix and of breast cancer have been found for daughters of women who took DES during pregnancy; fertility problems are also more common among these daughters.
