Anastrozole is a medication commonly prescribed for the treatment of hormone receptor-positive breast cancer. Its primary function is to lower estrogen levels in women, thus slowing or stopping the growth of certain types of breast tumors that need estrogen to grow. Proper dosage is crucial to ensure the medication is effective while minimizing potential side effects.
