Optimal treatment strategies and prognosis of breast cancer are largely dictated by three variables: molecular subtype, disease stage, and patient preferences.Limited data have been published regarding the knowledge level of breast cancer patients about their diagnosis. It has been reported that 13%–65% of patients do not know whether their tumor is hormone sensitive, 34%–70% are unaware of their HER2 status, and 28%–49% do not know their disease stage.Previous studies have demonstrated the feasibility and utility of educational interventions to improve breast cancer patients' awareness of their disease.
