Who should take aromatase inhibitors?
Women with hormone receptor-positive breast cancer who have gone through menopause at the time of diagnosis have 2 options for adjuvant hormone therapy: • They can begin treatment with tamoxifen for 2-5 years and switch to an aromatase inhibitor for another 2-5 years. • They can begin treatment with an aromatase inhibitor for 5 years. At this time, it is not known which treatment option is better. It is reasonable for women who have been taking tamoxifen for 2 or more years to switch to an aromatase inhibitor.
