NCT00651976
RATIONALE: Hormone therapy using letrozole may fight breast cancer by lowering the amount of estrogen the body makes. Giving letrozole before surgery allows us to monitor the effects of letrozole on the tumor on a molecular level and determine markers of response to treatment. PURPOSE: This study will show us how well letrozole works in treating postmenopausal women with stage I, II or III breast cancer that can be removed by surgery.
