The purpose of this study is to characterize the current patterns of care for patients with hormone-receptor-positive, advanced breast cancer who have failed one prior endocrine therapy in Brazil. To investigate patient-related, disease-related and physician-related characteristics that correlate with the use of either endocrine treatment or chemotherapy in such patients. And to evaluate patients' understanding of the treatment options and their participation in the choice.
