Brief Summary:

RATIONALE: Studying samples of breast tissue in the laboratory may help doctors learn more about the genes and proteins found in breast tissue.

PURPOSE: This phase I trial is studying genes and proteins in breast tissue from women undergoing surgery for breast cancer or core biopsy of the breast.

Condition or disease Intervention/treatment
Breast Cancer Genetic: microarray analysis Procedure: breast biopsy

Detailed Description:


  • Assess tumor gene expression information from women undergoing surgery for breast cancer or core biopsy sampling of the breast.

OUTLINE: This is a pilot study.

Tumor tissue is collected and analyzed for tumor gene expression by DNA microarray analysis for research studies.

PROJECTED ACCRUAL: A total of 100 patients will be accrued for this study.
