It has been reported that IL-6 acts as an essential agent, exerting different protumorigenic activities that intrinsically act on cancer cells through numerous mediators that support the proliferation, survival, and dissemination of these cells and that extrinsically act on cells that make up the tumor microenvironment, thus supporting angiogenesis and evasion of immune surveillance [39–42]. This evidence concerns the gene IL6 and neoplasm.
