RATIONALE: Diagnostic procedures, such as MRI, may help find ductal carcinoma in situ and find out how far the disease has spread. PURPOSE: This clinical trial is studying how well MRI works in assessing tumor size in women with ductal carcinoma in situ.
OBJECTIVES: Primary * Assess the contribution of MRI in accurately determining tumor size in women with ductal breast carcinoma in situ (DCIS). Secondary * Evaluate the sensitivity of MRI in detecting DCIS. * Evaluate the contribution of mammography in accurately determining tumor size. * Compare the contribution of MRI vs mammography in assessing tumor extension. * Compare the contribution of MRI vs mammography in assessing dense breasts. * Evaluate the morphology of DCIS by MRI. * Evaluate the curve of dynamic MRI in assessing DCIS. * Evaluate the impact of nuclear grade of DCIS by MRI. * Evaluate the rate of revision surgery. OUTLINE: Patients undergo clinical examination, mammography, ultrasound imaging, unilateral breast MRI, and tissue sampling.
