Association between breast cancer risk factors and molecular type in postmenopausal patients with hormone receptor-positive early breast cancer

ConclusionsThis analysis shows an association between HRT and the distribution of molecular subtypes of BC. However, no associations between other factors (e.g., age at diagnosis, body mass index, smoking status, age at menopause, number of deliveries, age at first delivery, breastfeeding history, or family history) were noted.
