乳腺癌已经成为中国女性发病率第一位的恶性肿瘤。在中国抗击COVID-19疫情取得阶段性胜利的时刻，乳腺外科医师应认真总结疫情期间开展乳腺肿瘤诊治的经验，并指导"后疫情阶段"的临床实践。其中，必须坚持患者最大获益和最小受害的理念，优化选择综合治疗方案。而综合评价乳腺癌患者的临床分期和分子分型是制定临床决策的关键。同时，美国外科学会以临床危险度为参考依据，针对临床外科处理原则制定了宏观指导意见，并提出基于疫情防控的需要，乳腺癌患者外科手术可能需要推迟6~8周时间的观点。

Breast cancer has become the most frequently diagnosed cancer in Chinese women. As Chinese doctors have reached a stage victory in fighting the epidemic, breast surgeons should start to reflect and improve their clinical treatment, concerning both the maximum benefit and minimum victimization for the patients, in such "post-epidemic " time.
