Aromatase inhibitors are a class of drugs used primarily in the treatment of hormone-sensitive breast cancer in postmenopausal women. They work by blocking the aromatase enzyme, which converts androgens into estrogens, thereby reducing estrogen levels in the body. This is crucial, as many hormone-sensitive cancers thrive on estrogen.
