Aromatase inhibitors (AIs) play a crucial role in the treatment of hormone-receptor-positive breast cancer, particularly in postmenopausal women. They work by inhibiting the aromatase enzyme, which converts androgens into estrogens, thus reducing estrogen levels in the body. Choosing the correct dosage of aromatase inhibitors is essential to ensure maximum efficacy while minimizing side effects.
