Title: Exercise Diet and Sex Hormones in Postmenopausal Women (NEW)
Brief Summary: RATIONALE: A low-calorie diet and/or exercise program may help lower an overweight or obese postmenopausal woman's risk of developing breast cancer. It is not yet known whether a low-calorie diet and/or exercise program are more effective than no diet or exercise program in lowering an overweight or obese postmenopausal woman's risk of developing breast cancer.

PURPOSE: This randomized clinical trial is studying the effect of a low-calorie diet and/or exercise program on risk factors for developing breast cancer compared with no diet or exercise program in overweight or obese postmenopausal women.
