Effect of Weight Loss on Breast Density Using Digital Mammography and MRI in Women Who Are At Increased Risk For Breast Cancer
- Conditions
- Healthy, no Evidence of Disease
- Interventions
- Procedure: magnetic resonance imagingProcedure: digital mammographyProcedure: conventional surgery
- Registration Number
- NCT01259076
- Lead Sponsor
- Northwestern University
- Brief Summary
Diagnostic procedures, such as digital mammography and MRI, may help measure how weight loss affects breast density in women who are at increased risk for breast cancer.
- Detailed Description
OBJECTIVES: I. To determine if weight loss in patients undergoing Roux en Y gastric bypass procedures has any effect on breast density as measured by mammography and breast MRI. OUTLINE: GROUP I: Participants undergo mammography and MRI at baseline and 1 year. Participants also undergo gastric bypass surgery. GROUP II: Participants undergo mammography and MRI at baseline and 1 year. After completion of study treatment, patients are followed up at 1 year.
