Comparison of epidemiological characteristics and prevention of breast cancer in China and the United States
Objective By comparing the epidemiological characteristics of the incidence and death of female breast cancer in China and the United States,the differences in prevention and screening strategies between China and the United States were analyzed to explore the prevention and control measures of female breast cancer in China.Methods Based on the relevant data released by the Global Burden of Disease in 2020,the National Cancer Center of China,and the China Health Statistical Yearbook,the new cases and deaths of breast cancer in Chinese and American women in 2023 were estimated respectively,and the incidence,mortality and time trend of breast cancer in Chinese and American women were analyzed.Results In China,376 789 new cases of female breast cancer and 116 791 deaths were expected in 2023.In the United States,approximately 297 790 women were expected to be newly diagnosed with breast cancer in 2023,representing approximately 15.2％of new cancer cases.About 43 170 women died from breast cancer,accounting for about 7.1％of all cancer deaths.The incidence of breast cancer in women in the United States during the period 1975-2020 gradually increased and then stabilized;In contrast,the incidence of breast cancer among Chinese women increased year by year during the period 1990-2020.In recent years,the incidence and mortality rates of breast cancer in Chinese women had increased more than those in the United States,and there was a large difference between urban and rural areas in China.Conclusions Both China and the United States face a large burden of female breast cancer,and the characteristics of female breast cancer in China are similar to those in the United States.To reduce the burden of breast cancer in Chinese women,further efforts should be made in various aspects,such as strengthening breast cancer education,raising public health awareness,improving diet structure,cultivating healthy lifestyle,increasing screening efforts,and improving medical level.
