The HER2 (human epidermal growth factor receptor 2) gene makes HER2 proteins (also called HER2/neu proteins). HER2 proteins are receptors on breast cells. HER2 receptors help control how a breast cell grows, divides, and repairs itself.
📌 If the HER2 gene doesn’t work properly, it can make breast cancer grow and spread faster. A pathology report will say whether the breast cancer is HER2-positive or HER2-negative.
