Background Worldwide breast cancer incidence correlates with socioeconomic status and increases in parallel with westernization, however urban–rural disparity and trends have not been adequately investigated in China. Methods The age standardized rate (ASR) of female breast cancer by population‐based cancer registration was compared between urban Shijiazhuang city and rural Shexian County in relation to socioeconomic status. The increasing trend of breast cancer in Shexian County from 2000–2015 was examined using Joinpoint analysis and the correlation with gross domestic product (GDP) per capita was analyzed. Results In 2012, the ASR of female breast cancer in Shijiazhuang was more than three times higher than in Shexian County (45.5/1 00 000 vs.13.8/1 00 000; P
