The study is for postmenopausal women taking aromatase inhibitors for adjuvant endocrine therapy - Participants with cognitive impairment are excluded due to dose titration instructions and completion of questionnaires - Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
