RATIONALE: Exercise may change the risk of developing breast cancer. It is not yet known whether low-intensity exercise or high-intensity exercise is more effective in lowering the risk of breast cancer.

PURPOSE: This randomized clinical trial is studying how well exercise programs work in healthy young women at increased risk of developing breast cancer.

Primary Outcome Measures:
  • Change in the area under the curve for urinary estrogen (E1G-AUC) adjusted for cycle length [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Effects of exercise on variables known to affect or reflect mitogenic activity as related to breast cancer risk [ Designated as safety issue: No ]
  • Changes in other physiologic parameters associated with breast mitotic activity [ Designated as safety issue: No ]
  • Extent to which changes in body composition and body mass mediate observed changes in E1G-AUC [ Designated as safety issue: No ]
  • Relationship between estrogen and progesterone from daily urinary measurements with observed menstrual cycle alterations (i.e., follicular and luteal phase length changes, and ovulatory status) [ Designated as safety issue: No ]

Estimated Enrollment: 160
