An aromatase inhibitor is a type of medication that works by blocking the enzyme aromatase, which is responsible for converting androgens into estrogen. Aromatase inhibitors are commonly used in the treatment of hormone receptor-positive breast cancer, as they help reduce estrogen levels in the body.

By inhibiting aromatase, these medications effectively lower the amount of estrogen available to fuel the growth of hormone-sensitive breast cancer cells. This can help slow down or even stop the progression of the disease, making aromatase inhibitors an important component of hormone therapy for breast cancer patients.

There are several different types of aromatase inhibitors available, including anastrozole, letrozole, and exemestane. These drugs may be used alone or in combination with other therapies, such as surgery, radiation, or chemotherapy, depending on the individual patient’s specific situation.
