Our research, in which the expression of AR and ER receptors in tumor tissue was determined in the first stage taking into account the number of cells having receptors and the intensity of their staining, showed that, in benign and low-malignancy tumors (adenoma and epithelioma), more cells show expression of AR and ER receptors than in malignant tumors (carcinoma). The gene discussed is AR; the disease is epithelial neoplasm.
