Aromatase inhibitors are medications commonly used in the treatment of hormone-sensitive breast cancer, particularly in postmenopausal women. They work by decreasing the amount of estrogen produced in the body, thereby slowing the growth of estrogen-dependent tumors. Proper dosage is crucial for the effectiveness of these medications and for minimizing potential side effects.
