Summary
Brief summary (as posted)
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at tumor tissue samples from patients with early-stage breast cancer.
