Screening and early diagnosis of breast cancer in China: a practice guideline

This practice guideline includes 50 recommendations and 5 expert consensus statements, with a scope of screening, early diagnosis, genetic testing on recurrence risk, and communication and training in the screening program. The formulation of recommendations considered best available evidence-based medicine, sense of worth and preferences of Chinese women, and cost and resource utilization. The implementation of recommended screening and diagnostic strategies need to consider the local contexts.
