What is Anastrozole?
Anastrozole is a medication primarily used to treat breast cancer in postmenopausal women. It functions as an aromatase inhibitor, which means it lowers estrogen levels in the body. Estrogen can promote the growth of certain types of breast tumors, so by inhibiting its production, Anastrozole helps to slow or reverse tumor growth.

How Anastrozole Works
Anastrozole works by blocking the aromatase enzyme, which is responsible for converting androgens into estrogen. Reduced estrogen levels can lead to lesser stimulation of hormone-sensitive tumors, effectively managing and potentially shrinking the tumor size.
