| [Purpose] To explore the incidence and mortality rates of breast cancer among women in Henan Province in 2020, and study the epidemiological characteristics of breast cancer among women in Henan Province from 2010 to 2020. [Methods] Based on the breast cancer incidence and mortality data stratified by urban and rural areas and age groups in Henan Province's tumor registry for 2020, and utilizing the province's household population statistics in the same year, this study comprehensively assessed female breast cancer epidemiological indicators. The analysis encompassed newly diagnosed/deceased cases, crude incidence/mortality rates, median morbidity, age-standardized rates, and cumulative incidence metrics.Utilizing the Joinpoint regression model, this study calculated the Annual Percentage Change (APC) and Average Annual Percentage Change (AAPC) for relevant epidemiological metrics. [Results] In 2020, Henan Province documented 24,744 new female breast cancer cases, with a crude incidence rate of 46.96/105, ASIRC of 38.43 and ASMRC of 35.71/105, respectively, representing 17.76% of all malignant tumor diagnoses in the province. Mortality data revealed 4,989 female breast cancer deaths, corresponding to a crude mortality rate of 9.47 per/105, with ASIRW of 6.8 ,and ASMRW of 6.72/105, accounting for 7.86% of total malignant tumor deaths. Urban female breast cancer epidemiological indicators in Henan were notably more severe than those in rural areas in 2020. Female breast cancer demonstrated the highest incidence frequency among individuals around 50 years of age, with mortality reaching its maximum in populations aged 85 and older. From 2010 to 2020, the overall incidence of female breast cancer in Henan showed a slow upward trend, while the mortality rate exhibited a significant downward trend (Incidence: AAPC=2.09%, P=0.01，95%CI：0.62%~3.58%; Mortality: AAPC=-3.49%, P=0.005, 95%CI：-5.62%~-1.30%). [Conclusion] Persistent elevated incidence and mortality patterns of breast malignancy among women in Henan Province. There is an urgent need to formulate corresponding preventive measures and control strategies to mitigate the harm of breast cancer to women’s health. |
