Abstract: Objective This study aimed to analyze the current epidemic situation of cancer in Yunnan province in 2020,and to provide theoretical basis for the prevention and treatment of cancer in Yunnan province. Methods The data on the incidence and mortality of cancer were collected from 129 cancer registration areas in Yunnan province in 2020.A total of 89 counties(cities,districts)that met the quality control standards were included in this analysis.Among them,there were 16 in urban areas,covering a population of 7,593,622(24.16%),and 73 in rural areas,covering a population of 23,838,542(75.84%).The number of malignant tumor cases,deaths,the crude incidence and China age-standardized incidence(China Standardized Incidence),the crude mortality and China age-standardized mortality(China Standardized Mortality),the cumulative incidence and mortality from 0 to 74 years old,as well as the order of cancer incidence and death were statistical analyzed. Results In 2020,66,719 new cases of cancer were reported from 89 tumor registration areas in Yunnan province,with a crude rate of 212.26/100,000 and the China age-standardized incidence of 150.33/100,000;The reported number of deaths from cancer was 39,251,with a crude mortality of 124.88/100,000 and the China age-standardized mortality of 82.45/100,000.The incidence and mortality of cancer were higher in men than those in female,and higher in rural than those in urban areas.According to the crude incidence rate and crude mortality,the top 5 cancers with the highest crude incidence were lung cancer,female breast cancer,colo-rectum cancer,liver cancer and thyroid cancer,and the top 5 cancers with the highest crude mortality were lung cancer,liver cancer,colo-rectum cancer,stomach cancer and female breast cancer. Conclusion Lung cancer,liver cancer,colo-rectum cancer and female breast cancer are still the key cancers for prevention and control in Yunnan province.The incidence of thyroid cancer is relatively high,and there are significant differences in the incidence and mortality of cancer between urban and rural areas and between sexes.The corresponding cancer prevention should be carried out according to the current epidemic situation of cancer in Yunnan province.
