Abstract
OBJECTIVES
Since 2002, the Korean government has provided breast cancer screening as part of the National Cancer Screening Program. This study reported trends in the screening rate among Korean women from 2005 to 2020, including organized and opportunistic screening for breast cancer.
METHODS Data from the Korean National Cancer Screening Survey, an annual cross-sectional nationwide survey, were collected using a structured questionnaire between 2005 and 2020. The study population included 23,702 women aged 40-74 years with no history of cancer. We estimated the screening rate based on the current recommendation of biennial mammographic screening for breast cancer. In addition, a joinpoint trend analysis was performed for breast cancer screening rates among various subgroups.
RESULTS In 2020, the breast cancer screening rate was 63.5%, reflecting an annual increase of 7.72% (95% confidence interval 5.53 to 9.95) between 2005 and 2012, followed by non-significant trends thereafter. In particular, a significant decrease in the breast cancer screening rate was observed in the subgroups aged 50-59 years old, with 12-15 years of education, and living in rural areas.
CONCLUSIONS Although there has been substantial improvement in breast cancer screening rates in Korean women, the trend has flattened in recent years. Therefore, continual efforts are required to identify subgroups with unmet needs and solve barriers to the uptake of breast cancer screening.

Summary
Korean summary
본 연구는 2005년에서 2020년까지 암검진수검행태조사 자료를 이용하여 40세 이상의 우리나라 여성의 유방암 검진 수검률이 추이에 대해 분석하였다. 우리나라 유방암 검진 수검률은 2020년 현재 63.5%이다. 하지만 지속적으로 증가하던 유방암 검진 수검률의 추이는 2012년 이후 정체되어 있으며 일부 사회경제적 계층에서는 감소하는 경향을 보였다.
Key Message
In Korea, despite of the high level of breast cancer screening rate, decreasing trends in some socioeconomic classes after 2012.
Continual efforts are required to identify subgroup with unmet needs and barriers to the uptake of breast cancer screening.
