Scientists uncover the hidden nerve network fueling breast cancer

Researchers have uncovered a surprising way triple-negative breast cancer may turn the body against itself. Tumors appear to recruit macrophages—immune cells normally involved in healing and fighting infection—and use them to release a protein called BDNF that draws nerves into the tumor. Those nerves may then help the cancer grow, resist treatment, and potentially spread.
