CHICAGO (Reuters) – Menopausal women who took hormone replacement therapy increased their risk of ovarian cancer by 38 percent, Danish researchers reported on Tuesday.
The study of more than 900,000 Danish women aged 50 to 79 found about one extra ovarian cancer for roughly 8,300 women taking hormone therapy each year.
At the time they got sick, 9 percent of the women were taking hormone therapy, 22 percent were previous users and 63 percent did not take it. The researchers calculated that current hormone use conferred a 38 percent higher risk of contracting the disease compared to non-users over the eight-year study.
Hormone therapy was linked to 140 extra cases of ovarian cancer in Denmark during the eight-year study, accounting for 5 percent of all cases in that period, the researchers reported in the Journal of the American Medical Association.
