In the tumor microenvironment, breast cancer cells participate in crosstalk with the surrounding stroma. This tumoral-stromal interaction forms a balance that dictates tumor suppressing or tumor promoting response mechanisms. Macrophages in the tumor microenvironment are plastic and can mediate several functions depending on their activation states. Tumor associated macrophages co-exist as two major phenotypes: anti-tumorigenic and immune-eliciting classically activated M1 as well as tumor-promoting and immune-suppressive alternatively activated M2 macrophages. Alternatively activated macrophages are specifically associated with more aggressive stages and poor clinical outcomes in breast cancer patients as they suppress the tumoricidal properties of the immune system, thus facilitating …
