Letrozole is a medication commonly prescribed for hormone-receptor-positive breast cancer, particularly in postmenopausal women. It works by inhibiting the aromatase enzyme, which is essential for the production of estrogen, thereby reducing the hormone levels that can fuel cancer growth. Getting the dosage right is crucial for achieving the best therapeutic outcomes while minimizing side effects.
