Objective To explore the incidence, age distribution and change tendency of female breast cancer in urban Shenyang from 2000 to 2009.
Methods The incidence data of female breast cancer recorded in Shenyang Center for Disease Control and Prevention from 2000 to 2009 were collected, and the incidence and standardized incidence of breast cancer were analyzed by using SPSS 16.0 software. The incidence trend was analyzed by means of χ2 trend test and linear regression.
Results The annual average crude incidence rate of female breast cancer in urban Shenyang from 2000 to 2009 was 46.03/100 000, while the annual average standardized incidence rate was 35.63/100 000, increased by 160.41% and 109.39% respectively during past 10 years, and the annual average increase was 11.22% and 8.56%, respectively. Both crude incidence rate and standardized incidence rate were in increasing trends with statistical significance (P lt;0.001). The crude incidence rate of the female at age of 50-64 showed a perpendicular rise trend, increased by 271.97%, and the annual average increase was 15.72%. The χ2 trend test and linear regression showed a significant difference (χ2=276.743, P=0.000; y= –22 355.560+11.205x, P=0.000).
Conclusion The incidence of female breast cancer in urban Shenyang tends to rise with a younger-aged trend, and the female at age of 50-64 are commonly affected.
