IL6 and breast cancer: Serum test results (Figure 4E) demonstrated that the expression of each factor in the MC group [group difference: IL-1β (9.264, 95% CI: 0.7616 to 17.77, p = 0.028), IL-6 (53.51, 95% CI: 28.79 to 78.22, p < 0.001), TNF-α (0.2314, 95% CI: 0.0274 to 0.4355, p = 0.021), and IFN-γ (32.72, 95% CI: 12.41 to 53.03, p < 0.001)] increased significantly than that in the BC group.
