A recent study consisting of 8067 Chinese women focused on the same molecular subtypes of breast cancer with us and demonstrated that postmenopausal women tended to have HER2‐overexpressing and triple‐negative subtypes.29 Also consistent with our study, another study on Northeast Chinese women found that postmenopausal status decreased the odds of luminal A and luminal B subtypes compared to controls.30 Therefore, previous studies based on Chinese population in different regions showed generally consistent results with our findings. Here, ERBB2 is linked to breast carcinoma.
