This breast cancer tissue microarray (TMA) includes paired cancerous and adjacent non-tumor breast tissues, providing a valuable resource for comparative studies and high-throughput analysis. The array contains 106 patient cases with 110 cores of 1.5 mm diameter. Each sample is annotated with pathology grade, TNM and clinical stage (AJCC 8th edition), and IHC marker results for ER, PR, HER2, and Ki-67, enabling comprehensive biomarker and disease progression research.

Applications:

• Breast cancer biomarker discovery and validation
• Comparative analysis of tumor and adjacent tissue
• Immunohistochemistry (IHC) studies
• Correlation of pathology with clinical outcomes
