Abstract:
Objective:To analyze the current situation for the mortality of Chinese female breast cancer and the trend of change in the past thirty years,and to provide scientific basis for prevention and control of breast cancer in China.Methods:The mortality data of breast cancer in Chinese female from 1987 to 2014 were collected,the trends of age-standardized rates and age-adjusted rates were described,and the variations via Joinpoint regression models were analyzed.Results:From 1987 to 2014,the mortality for the urban female breast cancer was greater than that for the rural females.There was a downward trend for urban women with an average decrease of 0.3％ for each year (P=0.06).While the average annual change for rural females showed an upward trend (AAPC=l.26％,P＜0.01).The gap between urban and rural females is narrowing gradually.The 40-59 age-adjusted rate for urban females decreased first and then it was increased with time moving forward.The mortality for rural females was continuously increased.Conclusion:From 1987 to 2014,the breast cancer mortality for urban females was overall higher than that for rural females.The mortality for rural females was continuously increased in the past years.The gap between urban and rural females is narrowing.We should pay specific attention to the prevention and treatment of breast cancer for the rural females.
