“…In our study, the percentage of BCS only accounted for 5.2% (131/2,525), which is similar to Zhang's study from China (5.6%) (Zhang et al, 2013). MRM is decreasing and have been a non-mainstream operation pattern in developed countries (Ko et al, 2012;Piscitelli et al, 2012). While, our study showed MRM was still the major surgical treatment accounting for 71.8%, similar to another study from China (79.7%), which is much higher than developed counties/areas (Ko et al, 2012;Turashvili et al, 2011;Wei et al, 2010).…”
