RATIONALE: Diagnostic procedures, such as dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI), magnetic resonance spectroscopy (MRS), and tissue proteomics, may help doctors find and diagnose breast cancer and plan the best treatment. PURPOSE: This clinical trial is studying MRI and MRS with or without tissue proteomics analysis to see how well they work in evaluating healthy women and women who are undergoing surgery for breast cancer.
OBJECTIVES: * To correlate data obtained by DCE-MRI and MRS in healthy women and in women who are undergoing surgery for breast cancer with data obtained by conventional X-ray mammography, tissue proteomics, and histopathology. * To evaluate the impact of MRSI data on treatment planning for radiotherapy and/or surgery. OUTLINE: Healthy participants undergo dynamic contrast-enhanced (DCE)-MRI and magnetic resonance spectroscopic (MRS) for longitudinal studies of breast imaging and spectroscopy. Patients with breast cancers undergo DCE-MRI and MRS prior to initiation of treatment (i.e., surgery, chemotherapy, or radiotherapy). After treatment has begun, patients then undergo repeat imaging (not more than 1 per month) for follow-up assessments and longitudinal studies. Breast tissue samples are collected from patients undergoing surgery. Samples are evaluated by histopathological and proteomic analysis for correlation with DCE-MRI and MRS findings. The study interventions are discontinued after definitive surgery is performed. PROJECTED ACCRUAL: A total of 10 healthy participants and 40 patients with breast cancer will be accrued for this study.

removal of breast tumor or removal of the entire breast in which the tumor is located
Prior to initiation of treatment
Correlation of data obtained by DCE-MRI and magnetic resonance spectroscopy (MRS) with data obtained by conventional X-ray mammography, tissue proteomics, and histopathology in women with breast cancer
Imaging and spectroscopic studies are performed before surgery. After surgery, this data will be compared and contrast with data obtained from conventional mammograms and the patient's tissue.
Time frame: At time of breast surgery
Evaluation of the impact of MRS data on treatment planning for radiotherapy and/or surgery in women with breast cancer
Investigators will evaluate the effectiveness of spectroscopic data used to plan for the patient's post-imaging surgery and/or post-surgical radiotherapy.
Time frame: After the last scan
