IL‐1β promotes tumor progression and counteracts immunosurveillance by recruiting myeloid cells, such as myeloid‐derived suppressor cells (MDSCs) and tumor‐associated macrophages (TAMs).[qv: 31,32] This suggests that BRCA1 mutation could establish a tumor‐associated microenvironment for cancer progression via inflammasome activation. Here, IL1B is linked to cancer.
