Abstract: Objective The aim of this study was to analyze the incidence and mortality of all cancers of Baiyin in Gansu province in 2018. Methods Based on data of cancer incidence and mortality of Baiyin in Gansu province in 2018,the incidence and mortality rates,ranking and constituent ratio were calculated.The age-standardized rate was calculated and adjusted by Chinese standard population in 2000(ASIRC,ASMRC)and World standard(Segi′s)population(ASIRW,ASMRW),respectively. Results Malignant tumors incidence rate was 272.67/10⁵ in Baiyin Municipal in 2018,ASIRC and ASIRW were 178.33/10⁵ and 172.91/10⁵,and the cumulative rate(0-74 years old)was 18.93%;the top 10 incidence accounted for 74.73% of all cancers,The top 5 cancers with highest incidence were stomach cancer,lung cancer,liver cancer,colorectal cancer and breast cancer.Malignant tumors mortality rate was 146.55/10⁵ in Baiyin Municipal in 2018,ASMRC and ASMRW were 86.39/10⁵ and 84.57/10⁵,and the cumulative rate(0-74 years old)was 9.29%;the top 10 mortality rates accounted for 84.34% of all cancer,The top 5 cancers with highest mortality were stomach cancer,lung cancer,liver cancer,colorectal cancer and pancreas cancer.ASIRC and ASMRC in male is higher than that in female,rural areas are higher than urban areas;the incidence and mortality reached a peak in the 80-84 age group.Pingchuan and Jingtai have the highest rate of ASIRC and ASMRC,and Baiyin county has lowest of ASIRC and ASMRC. Conclusion The incidence and mortality rate of stomach cancer,lung cancer,liver cancer,colorectal cancer,breast cancer,pancreatic cancer is high,it is a cancer that needs to be prevented and controlled;since incidence and mortality of breast cancer and cervical cancer rank the top 5 in female,more attentions should be than male malignant tumors for female to prevention and control.
