Breast Carcinoma and Matched Lymph Node Metastasis Tissue Microarray

The Breast Carcinoma and Matched Regional Lymph Node Metastasis Tissue Microarray (48 cases / 96 cores, 1.5 mm) provides a comprehensive tool for studying tumor progression, metastasis, and biomarker expression in breast cancer. Each case includes detailed clinical data such as TNM classification, AJCC 8th edition stage, pathology grade, and immunohistochemistry (IHC) results for ER, PR, and HER2 markers. This high-quality tissue array supports translational research, diagnostic assay validation, and targeted therapy studies in oncology and molecular pathology.
