Exposure in utero to a drug used to prevent miscarriage can lead to an increased risk of developing cancer, according to researchers at The University of Texas Health Science Center at Houston (UTHealth Houston).

The study was published today in the American Journal of Obstetrics and Gynecology.

The drug, 17α-hydroxyprogesterone caproate (17-OHPC), is a synthetic progestogen that was frequently used by women in the 1950s and 1960s, and is still prescribed to women today to help prevent preterm birth. Progesterone helps the womb grow during pregnancy and prevents a woman from having early contractions that may lead to miscarriage.

“Children who were born to women who received the drug during pregnancy have double the rate of cancer across their lifetime compared to children born to women who did not take this drug,” said Caitlin C. Murphy, PhD, MPH, lead author on the study and associate professor in the Department of Health Promotion and Behavioral Sciences at UTHealth School of Public Health in Houston. “We have seen cancers like colorectal cancer, pancreatic cancer, thyroid cancer, and many others increasing in people born in and after the 1960s, and no one really knows why.”
