Abstract: Objective The objective of this study was to analyze the incidence and mortality of female breast cancer in cancer registration areas of Gansu province in 2019 and the change trend of female breast cancer incidence and mortality from 2010 to 2019,so as to provide data support for the prevention and treatment of breast cancer. Methods The incidence and mortality data of breast cancer and related demographic data in all cancer registration areas in Gansu province from 2010 to 2019 were collected.The incidence,mortality,age-standardized incidence by Chinese standard population(ASIRC),age-standardized mortality by Chinese standard population(ASMRC),age-standardized incidence by World standard population(ASIRW)and age-standardized mortality by World standard population(ASMRW),cumulative incidence and other key indicators of female breast cancer in each cancer registration area were calculated according to urban and rural distribution and age groups.Joinpoint linear regression was used to analyze the annual change trend of incidence and mortality of female breast cancer in cancer registration areas in Gansu province from 2010 to 2019. Results In 2019,the number of new cases from female breast cancer in the cancer registration areas of Gansu province was 1,502 cases,accounting for 13.14% of all new malignant tumors in women.The incidence was 33.00/100,000,ASIRC and ASIRW were 23.83/100,000 and 23.81/100,000,respectively,and a cumulative rate of 0-74 years old was 2.34%.The incidence of breast cancer in urban and rural areas was 22.25/100,000 and 26.59/100,000,respectively.In 2019,the number of female breast cancer deaths in the cancer registration areas of Gansu province was 254,accounting for 5.61% of all female malignant tumor deaths.The crude mortality was 5.58/100,000,ASMRC and ASMRW were 3.70/100,000 and 3.90/100,000,respectively.The cumulative rate of 0-74 years old was 0.39%.The ASMRC of breast cancer in urban and rural areas was 3.63/100,000 and 3.79/100,000,respectively.The annual change trend in the ASIRC of female breast cancer in the province from 2010 to 2019 was not statistically significant(APC=-0.35%,P=0.81),while ASMRC decreased by an average of 9.85% per year(APC=-9.85%,P=0.03). Conclusion Breast cancer is a high incidence malignant tumor that threatens the physical and mental health of female residents in Gansu province,and it is a kind of cancer that women focus on.We should actively screen the risk group of women.
