Breast cancer treatment has undergone a significant transformation, evolving from broad-spectrum chemotherapy to highly targeted therapies that address specific molecular subtypes. Today, treatment is largely guided by such as hormone receptors (ER/PR) and the human epidermal growth factor receptor 2 (HER2), which allow for a "precision medicine" approach. 1.

Targeted drugs recognize specific markers, typically proteins, that help cancer cells grow and spread. 2. Targeted Therapies
