Exemestane is primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It works by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogen. By lowering estrogen levels, it helps to slow or stop the growth of certain types of breast tumors that rely on estrogen to develop and proliferate.

This medication is often prescribed as an adjuvant therapy following initial treatments like surgery or radiation to reduce the risk of cancer recurrence. It may also be used in advanced stages of breast cancer to manage the disease and control its progression. Additionally, exemestane is sometimes utilized in the prevention of breast cancer in high-risk postmenopausal women.

Patients typically take exemestane orally, and it is usually administered once daily. It is important for individuals to follow their healthcare provider’s instructions and attend regular check-ups to monitor the effectiveness and manage any potential side effects.
