IL6 and breast cancer: Compared with the BC group, the DN group had very significantly increased levels of the pro-inflammatory factor IL-1β (p < 0.01) and non-significantly increased levels of IL-6 (p ≥ 0.05), as well as a very significantly reduced expression of the anti-inflammatory factor IL-10 (p < 0.01); compared with the DN group, the DM group had very significantly reduced levels of the pro-inflammatory factors IL-6 and IL-1β (p < 0.01) and increased levels of the anti-inflammatory factor IL-10 (p ≥ 0.05) (Figure 6).
