Official title

Mechanisms of Prevention of Ovarian Cancer by Oral Contraceptives

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Use of oral contraceptives (OCs) reduces a woman's risk of ovarian cancer very significantly and the protective effect continues for at least 25 years after use of OCs is stopped; the mechanisms of how this occurs are not understood. We are proposing here to directly study the effect of OCs on the fallopian tube and inclusion cysts within the ovary - sites from which most ovarian cancers are thought to arise - in order to better understand the mechanistic basis for OC protection against ovarian cancer. We think the protection results from reduced cell proliferation. It will lay the foundation for further studies to ensure that the protection against ovarian cancer afforded by 'traditional' OCs is not lost with alterations in OC formulation, and, if possible, to guide development of OC formations to improve further on the protection afforded by OCs.
