Letrozole is a medication commonly used in the treatment of hormone-receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by lowering estrogen levels in the body, thereby slowing or stopping the growth of certain types of breast tumors that require estrogen for growth. Understanding the appropriate dosage of letrozole is crucial for its effectiveness and minimizing side effects.
