Hormone Therapy and the Impact of Estrogen Intake on the Risk of Ovarian Cancer

Abstract

Oral HT is associated with risk of ovarian cancer in women who have not undergone hysterectomy. Our results imply that the risk increases with cumulative oral estrogen intake but not with duration of HT, indicating that the increased ovarian cancer risk associated with oral HT may be diminished substantially by minimizing the daily dose of estrogen from oral HT.
