On July 9, 2002, a major clinical trial of the risks and benefits of hormone replacement therapy (“HRT”) for menopausal women was cut short. The trial, which involved 16,660 women, was halted because the data revealed that women undergoing HRT using the drug Prempro, a combination pill of estrogen and progestin, allegedly had a higher risk of breast cancer, coronary heart disease, stroke and pulmonary embolisms.
