Abstract Background Although several studies have evaluated health-related quality of life (HRQoL) in breast cancer survivors, few have compared HRQoL between breast cancer survivors and an age-matched general population in terms of improvement patterns according to time after surgery. Thus, we compared the postoperative changes in HRQoL in breast cancer survivors with those of age-matched general population groups using the EuroQoL five-dimension three-level questionnaire (EQ-5D-3 L). Methods EQ-5D-3 L questionnaires were obtained from 686 breast cancer survivors during follow-up visits. They were divided into five groups according to time after surgery: 0–5 months, 6–11 months, 12–35 months, 36–59 months, and ≥ 60 months. Their EQ-5D-3 L data, covering five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), were compared with those of age-matched general population groups. Results The mean EQ-5D-3 L index of breast cancer survivors was high in group with longer time after surgery and the mean EQ-5D-3 L index of breast cancer group over 5 years after surgery was similar to that of an age-matched general population (0.919 vs 0.928, p = 0.305). Although there were deficits in all dimensions of breast cancer survivors, motility eventually exceeded that of general population groups and self-care and usual activities of groups over 3 years after surgery matched those of general population however, pain/discomfort and anxiety/depression of survivors over 5 years after surgery remained worse than those of the general population (p = 0.028, p < 0.001). Conclusions Motility, self-care, and usual activities decreased in the early postoperative period for breast cancer survivors but showed recovery after 3 years. However, pain/discomfort and anxiety/depression remained poorer in these patients than in the general population for many years.
