Given the high correlation between positive expression and the concentration of H-Ras oncoprotein (Rs=0.71, p=0.03), patients were divided depending on the concentration of H-Ras protein in breast cancer tissue into the study group with a positive concentration of oncoproteins (n=43) and a comparison group in which the studied oncoprotein was absent (n=57). This evidence concerns the gene HRAS and breast carcinoma.
