Summary

This trial will screen and assess risk reducing interventions for those at increased risk of endometrial cancer. A risk model and Progesterone test will identify those to receive standard of care and lifestyle interventions.

Who is the study for?
This trial is for postmenopausal individuals at least three years past their last menstrual period, who still have an intact uterus. It's not open to those on hormone therapy for menopause, taking male hormones or anti-endocrine drugs like tamoxifen, using aromatase inhibitors, experiencing abnormal uterine bleeding, or with an IUD.
What is being tested?
The study tests the feasibility of a screening method and risk-reducing treatments in people at high risk for endometrial cancer. Participants will take Provera (medroxyprogesterone acetate) for ten days; if they bleed afterwards, it indicates potential endometrial proliferation and leads to standard care including possible biopsy and hormone therapy.
What are the potential side effects?
Provera may cause side effects such as nausea, breast tenderness, headache, insomnia, mood swings and withdrawal bleeding. Long-term use can sometimes lead to increased risks of blood clots or changes in menstrual flow when used by premenopausal women.
