Summary
Breast cancer screening rates in four Asian countries averaged 24% for clinical breast exams and 18% for mammography over the last decade. Many Asian nations lack sufficient screening data, highlighting the need for improved cancer control policies.
Area of Science:
- Oncology
- Public Health
- Epidemiology
Background:
- Breast cancer is a significant cause of mortality in women over 50.
- This study focuses on breast cancer screening trends in Asian countries.
Purpose of the Study:
- To determine the prevalence and trends of breast cancer screening in selected Asian nations.
- To identify data gaps in breast cancer screening across Asia.
Main Methods:
- Systematic review and meta-analysis of 41 studies from 14 Asian countries (2012-2023).
- Searched PubMed, Web of Science, and Scopus databases.
- Utilized random effects meta-analysis with Stata 17 for pooled estimates.
Main Results:
- Pooled screening rates in China, Iran, Japan, and Korea: 24% for clinical breast examination (CBE) and 18% for mammography.
- Data spans from 2012-2023, covering 14 Asian countries.
- Identified significant data limitations in most Asian countries regarding screening rates.
Conclusions:
- Insufficient data on breast cancer screening in many Asian countries due to a lack of national surveys and registries.
- Emphasizes the critical need to strengthen cancer control policies and breast cancer screening programs in Asia.

01:21Cancer Survival Analysis
328
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
