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

Drugs like Anastrozole (Arimidex) , Letrozole (Femara), and Exemestane (Aromasin) are primarily for postmenopausal women. They block the aromatase enzyme, which is necessary for making estrogen in the body. 2. Targeted Therapies

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.
