IL1B and cancer: In consistent with our findings, previous studies have also reported that the high expression of IL1α, IL1β or IL8 could increase tumor growth and metastasis of various types of cancer cells, including TNBC cells.[42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56] Furthermore, elevating the expression of IL1β or IL8 in macrophages after the co‐culture treatment enhanced breast tumor growth and metastasis.[57, 58]
