Breast Cancer Screening Programs in China: Implementation, Challenges, and Future Perspectives

Area of Science:

• Public Health
• Oncology
• Medical Imaging

Background:

• China faces a high burden of breast cancer, with the highest global incidence.
• A national screening program initiated in 2009 targets women aged 35-64.
• The program utilizes ultrasonography (US) and mammography, with US being crucial due to resource limitations and dense breast prevalence.

Purpose of the Study:

• To review the implementation and outcomes of China's national breast cancer screening program.
• To evaluate the specific role and effectiveness of ultrasonography (US) in this screening context.
• To identify key challenges and future directions for improving breast cancer screening in China.

Main Methods:

• Review of China's population-based breast cancer screening program implementation.
• Analysis of the role of ultrasonography (US) alongside mammography.
• Discussion of program achievements, challenges, and future strategies.

Main Results:

• China's screening program has expanded to cover a significant population.
• Ultrasonography (US) is integral to the program, addressing resource constraints and dense breast tissue.
• The program's real-world implementation offers insights for global breast cancer screening efforts.

Conclusions:

• China's breast cancer screening program demonstrates significant implementation efforts and achievements.
• Ultrasonography (US) plays a vital role in overcoming specific challenges within the Chinese context.
• Understanding these practices can inform and enhance breast cancer screening strategies internationally.
