“…The majority of the patients in the study cohort were Chinese, and expected to have similar physical attributes in terms of breast tissue volume as Chinese women elsewhere. Still, BCT rates in the study cohort are higher than in other Chinese-dominant countries (Chuwa et al, 2009;Yau et al, 2009;Yip et al, 2009;Chang et al, 2011;Wang et al, 2011) and are similar to, if not also higher than, those reported in Western countries (Lee et al, 2009;McGuire et al, 2009;Garcia-Etienne et al, 2012;Agarwal et al, 2014). Hence, the issue of smaller breast tissue volume and its impact on BCT rates needs further investigation.…”
