This article describes the breast cancer statistics in Korea, including the incidence, type of surgical procedure, stage, and molecular subtype, using the Korean Breast Cancer Society (KBCS) and Korea Central Cancer Registry data. There were a total of 26,534 new breast cancer diagnoses in 2017 in Korea, of which 4,139 were carcinoma cases and 22,395 were invasive cancer cases. The age standardized rate of breast cancer was 75.3 per 100,000 women in 2017 (63.0 of invasive carcinoma and 12.3 of carcinoma ), and it has been steadily increasing across all age groups. Breast cancer occurred most commonly in the 40-49 age group. Compared to 2016, breast conserving surgery (BCS) has increased, and 67.4% of patients were treated with BCS in 2017. The proportions of stage 0 and stage I have continued to increase, accounting for 60.7%. The most common subtype of breast cancer was hormone receptor (HR) positive and human epidermal growth factor receptor-2 (HER2) negative type comprising 65.9% of the cases, whereas HR negative and HER2 positive type was the rarest comprising 10.2% of the cases. The 5-year relative survival rate of breast cancer patients had increased by 14.0% from 79.2% in 1993-1995 to 93.2% in 2013-2017. It is essential to actively enter breast cancer data into the KBCS registry to improve our understanding.
本文利用韩国乳腺癌协会（KBCS）和韩国中央癌症登记处的数据，描述了韩国的乳腺癌统计数据，包括发病率、手术方式、分期和分子亚型。2017年韩国共有26534例新发乳腺癌诊断病例，其中4139例为原位癌病例，22395例为浸润性癌病例。2017年乳腺癌的年龄标准化发病率为每10万名女性75.3例（浸润性癌为63.0例，原位癌为12.3例），且在所有年龄组中都在稳步上升。乳腺癌最常发生在40-49岁年龄组。与2016年相比，保乳手术（BCS）有所增加，2017年67.4%的患者接受了保乳手术治疗。0期和I期的比例持续上升，占60.7%。乳腺癌最常见的亚型是激素受体（HR）阳性和人表皮生长因子受体2（HER2）阴性型，占病例的65.9%，而HR阴性和HER2阳性型最为罕见，占病例的10.2%。乳腺癌患者的5年相对生存率从1993-1995年的79.2%提高到2013-2017年的93.2%，提高了14.0%。积极将乳腺癌数据录入KBCS登记处对于增进我们的了解至关重要。
