Definitions
- the present invention relates to an agent for preventing postoperative recurrence of premenopausal breast cancer comprising 1 GnRH agonist or angina gonist, a menopause comprising a sustained-release preparation containing 2 GnRH agonist or angina gonist or an implant.

- moxifen is an estrogen receptor antagonist and shows its efficacy by competing with endogenous estrogen. Therefore, the effect of premenopausal estrogen synthesis in the ovaries is lower than in postmenopausal cases, because endogenous estrogen levels are higher than in postmenopause, where estrogen is not synthesized in the ovaries.
