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.

Abstract
OBJECTIVES
Through a survey on perception of lung cancer screening and accompanying medical radiation exposure in Korea, the present study was to investigate its current situations and evaluate various perception of physicians regarding it in order to propose measures for improvements.
METHODS
Medical specialists in national cancer screening institutions selected through stratified random sampling were subjected to face-to-face interview using a structured questionnaire. We investigated physicians’ perception on effectiveness of lung cancer screening depending on screening modality, selection criteria for subjects of screening, types of equipment used to screen, and perception for seriousness of adverse effects following the test. In addition, odds ratios to underestimate risk of radiation exposure from screening were calculated through logistic regression analysis.
RESULTS
Each response that chest X-ray is effective for lung cancer screening and that smoking history is not considered prior to screening recommendation accounted for more than 60% of respondents, suggesting the chance of unnecessary screening tests. Regarding adverse effects of lung cancer screening, about 85% of respondents replied that false positive, radiation exposure, and overdiagnosis could be ignored. About 70% of respondents underestimated radiation dose from lung cancer screening, and a low proportion of physicians informed patients of radiation exposure risk.
CONCLUSIONS
It was found that most physicians underestimated harms of lung cancer screening including radiation exposure and were lack of awareness regarding lung cancer screening. It should be noted that physicians need to have proper perceptions about screening recommendation and accompanying possible harms, for successful implementation of the screening program.
Summary
Korean summary
전국 100여개 국가암검진 기관을 대상으로 폐암검진 관련 설문을 수행한 결과, 효과적인 폐암검진의 수단이나 방법에 대한 이해 및 검사에 수반되는 각종 부작용에 대한 의사들의 인식이 확연히 부족한 것으로 조사되었다. 그 중에서도 특히 의료방사선 노출에 대한 낮은 인지도는, 촬영 시 피폭량에 대한 전반적인 과소평가 및 방사선 노출 위험과 관련한 환자 교육의 부재를 통해 확인할 수 있었다. 인구집단 대상 선별검사의 도입에 따른 잠재적인 위해 가능성과 그 결과에 대한 고민은 반드시 필요하며, 이와 관련된 의료제공자들의 인식 개선을 촉구하는 본 연구는 정책 도입에 앞서 선결되어야 할 과제로서 공중보건학적 측면에서 중요한 의의를 지닌다.
