Pathology of Kenyan breast cancer tissue samples. a Experimental design flowchart for this study. Samples were collected, analyzed for pathology, processed to create a tissue microarray, stained for clinical marker immunohistochemistry, and quantified by statistical analysis. b Pie chart representations of the distribution of cancer (left) and benign/not cancer (right) pathologies in Kenyan breast tissues analyzed after H&E staining. Most of these patients were diagnosed with invasive ductal carcinoma (IDC) and mucinous IDC. Most benign samples fell into the category that includes benign mammary, inflammatory tissue, and fibrocystic disease. (C) H&E staining of representative Kenyan breast cancer samples analyzed for pathology. Both Patient 1 and Patient 2 have invasive ductal carcinoma (IDC). Patient 2 has significant immune cell infiltration
