The Role of Tissue Microenvironment in Breast Cancer Development and Importance of its Behavioral Profiling for Individually Tailored Therapy

Abstract

Pavol Zubor

Invasive breast cancer is the endpoint of complicated evolutionary process starting in TDLU of mammary gland. It is the network of multiple-step mechanism including cell proliferation, differentiation, atypical intracellular expression and signaling leading to the misbalance between mammary epithelial cells and breast tissue microenvironment. The disruption of epithelial-stromal equilibrium can lead to the epithelial carcinogenesis, progressive stromal invasion and metastatic spread in the final stages. Although we know some of the histopathologic features in these mechanisms, the molecular profile of these events is still not adequately responded, and remains the scope for future research.
