NCT00569049

Brief Summary

This is a research-based study that is looking at the biologic features of breast tissue, lymph node tissue, or blood in order to study breast cancer development growth, and spread. Through tissue and/or blood samples we hope to gain further knowledge and understanding of how to improve diagnosis and treatment of breast cancer by identifying the molecular markers that predict clinical outcome and response to therapy.
