Objective: Based on cancer registry data, the present work aimed to analyze breast cancer survival and epidemiology in China. Methods: The cancer data was retrieved from the National Central Cancer Registry Database. The new diagnosis situation and the number of deaths due to breast cancers were estimated. The time trend and survival for breast cancer were also analyzed. Results: About249,000 new cases, with a 37.86/100,000 crude incidence rate, of female breast cancer were diagnosed in China in 2011. The crude incidence rate increased over the past ten years, and the trend for age-standardized rate increased gradually. Approximately 60,000 deaths were caused by breast cancer in China in 2011, with a crude mortality rate of 9.21/100,000. The crude mortality for females with breast cancer in China increased over the past several decades; however, after regulation of age-standardized rate, this increasing trend declined. The combined 5year age-standardized relative survival rate was 73.0%(95% CI: 71.2% to 74.9%), and the 1, 3, and 5 year observed survival rates were 90.5%,80.0%, and 72.7%, respectively. Conclusion: Breast cancer is a major cancer that threatens the people in China. Therefore, the burden of breast cancer is still heavy. The task of cancer treatment remains severe and serious.
