Compared with never use, ≥10 years' duration of OC use was associated with lower risk (multivariable IRR = 0.45, 95% CI, 0.27–0.74), but risk was higher among current users of estrogen-only (IRR = 3.78, 95% CI, 1.69–8.43) and estrogen plus progestin FMH (IRR = 1.55, 95% CI, 0.78–3.11). Risk was not increased among former users of estrogen-only (IRR = 0.87, 95% CI, 0.44–1.72) or estrogen plus progestin FMH (IRR = 0.63, 95% CI, 0.36–1.09).</jats:p> <jats:p>Conclusions: Current use of estrogen-only and estrogen plus progestin FMH was associated with increased risk of endometrial cancer.
