Abstract: Objective The objective of this study was to analyze the incidence and mortality of malignant tumors in cancer registration areas of Yunnan province in 2018. Methods The data on the incidence, death, and population of malignant tumors in 46 cancer registration areas in Yunnan province in 2018 were collected. The incidence, mortality, age-standardized incidence and mortality, the cumulative rate from 0 to 74 years old, as well as ranking and composition of the top 10 malignant tumor incidence and mortality were analyzed, and stratified by region, gender and age. The standardized rates were calculated using the China 2000 national census standard population age structure and Segi′s world standard population age structure, respectively. Results In 2018, the crude incidence of malignant tumors was 214.84/100,000 in tumor registration areas of Yunnan province, and China age-standardized rate was 155.99/100,000 and world age-standardized rate was 167.30/100,000. The age specific incidence was at a low level before the age of 45, and rose rapidly after the age of 45. It reached its peak at the age of 80 to 84. The main malignant tumors were lung cancer, female breast cancer, colorectal cancer, liver cancer, and cervix cancer. The crude mortality of malignant tumors was 128.63/100,000 in the cancer registration areas of Yunnan province in 2018, the China and world age standardized rates were 88.50/100,000 and 98.78/100,000, respectively. The mortality of malignant tumors was at a relatively low level before the age of 45, rapidly increasing after the age of 45, reaching the peak of death at the age of 85+. The mortality of all age groups in males was higher than that in females. The main malignant tumors were lung cancer, liver cancer, colorectal cancer, stomach cancer and female breast cancer in the order of death. The incidence of prostate cancer was higher than that of Western China, and the incidence of esophageal cancer was lower than that of Western China. Conclusion The incidence of malignant tumors in cancer registration areas in Yunnan province is lower than that in Western China. Lung cancer, female breast cancer, colorectal cancer, liver cancer and cervical cancer are the cancers that need to be focused on prevention and treatment. The incidence of prostate cancer and esophageal cancer has local characteristics.
