This phase II trial studies the effect of megestrol acetate alone or in combination with metformin in preventing the progression of uterine pre-cancer (endometrial intraepithelial neoplasia) to endometrial cancer. Megestrol acetate is a drug used to block estrogen and suppress the effects of estrogen and androgens. It is the current non-surgical treatment of endometrial intraepithelial neoplasia. Metformin is a drug that has been found to have anti-cancer properties. Giving metformin and megestrol acetate together may decrease the growth of endometrial intraepithelial neoplasia in the uterus better than megestrol alone.
