In 2022, nearly 2.3 million new cases of breast cancer were reported globally, with less than half of these cases originating from Asia. Despite the relatively low incidence of breast cancer in most parts of Asia, the mortality-to-incidence ratio remains high. Low-income countries lack resources for breast cancer screening, whereas high-income countries fail to fully benefit from national breast screening programs because of the underutilization of preventive healthcare services. There is a notable difference in the age distribution of breast cancer cases between Asian and Western populations, with the prevalence peaking approximately a decade earlier in Asian women and most commonly affecting those aged 40-50 years. Existing literature on breast cancer trends, screening guidelines, and clinical practices in Asian countries, particularly regarding regional variations and healthcare system differences, is relatively sparse. Gaining a deeper understanding of how different Asian countries are implementing breast cancer screening in response to the rising incidence of the disease can help identify tailored strategies for early detection, ultimately contributing to a reduction in breast cancer-related mortality. This review explored the current breast cancer landscape, including breast cancer screening guidelines and outcomes of screening examinations in Asia, highlighting key challenges and future directions.
2022年,全球报告了近230万例乳腺癌新发病例,其中不到一半的病例来自亚洲。尽管亚洲大部分地区乳腺癌发病率相对较低,但死亡率与发病率之比仍然很高。低收入国家缺乏乳腺癌筛查资源,而高收入国家由于预防性医疗服务利用不足,未能充分从国家乳腺癌筛查计划中受益。亚洲和西方人群乳腺癌病例的年龄分布存在显著差异,亚洲女性的患病率峰值大约提前十年出现,最常见于40至50岁的女性。关于亚洲国家乳腺癌趋势、筛查指南及临床实践(尤其是区域差异和医疗体系差异方面)的现有文献相对较少。深入了解不同亚洲国家如何针对乳腺癌发病率上升实施筛查,有助于确定早期检测的定制策略,最终降低乳腺癌相关死亡率。本综述探讨了亚洲当前的乳腺癌状况,包括乳腺癌筛查指南及筛查检查结果,突出了关键挑战和未来方向。
