OBJECTIVES:
* Estimate the diagnostic yield and positive predictive value of breast magnetic resonance imaging (MRI) for the detection of cancer in women who are at greater than 25% lifetime risk for developing breast cancer.
* Compare the diagnostic yield and positive predictive value of MRI with conventional breast cancer screening (mammography and physical examination) for the detection of breast cancer in women with a greater than 25% lifetime risk of developing breast cancer.
OUTLINE: All patients receive a physical exam within 90 days of initial MRI scan. Patients undergo a two view screening mammogram within 3 months prior to study entry. Patients undergo an MRI with gadolinium contrast at entry. All lesions identified as suspicious on physical examination, mammography, or MRI undergo a core needle or excisional biopsy.
PROJECTED ACCRUAL: A total of 200 patients will be accrued for this study within 2 years.
