Compared to the controls, BC cases had a higher mean blood concentration of most of the analysed inflammatory biomarkers, i.e., interleukin-6 (4.06 versus 2.46 pg/mL), leukocyte count (7.10 versus 5.74 × 103 cells/μL), including absolute granulocyte count (4.51 versus 3.26 103 cells/μL), which were mostly neutrophils (4.39 versus 3.02 × 103 cells/μL), as well as the mean ratio of granulocyte-to-lymphocyte (2.36 versus 1.70; Table 2). This evidence concerns the gene IL6 and breast cancer.
