Self-detection remains a primary means of breast cancer detection in Beijing, China
Translational Breast Cancer Research
Breast cancer in China is usually identified at a later-stage compared to developed countries, and efforts have been made to improve early detection over the past years. This cross-sectional study aimed to determine the current situation of breast cancer detection and screening in a cohort of Chinese breast cancer patients. Methods: Three hundred and ten consecutive female breast cancer patients newly diagnosed and treated in Beijing Tsinghua Changgung Hospital between 2015 and 2021 were
... ed. Clinicopathological data were retrieved from the patient's medical records and every individual completed surveys assessing demographics, mode of detection, screening behavior and barriers to screening. Results: Among the 310 patients, 72.6% had self-detected diseases (mostly through identification of a breast lump), 24.5% were ultrasound screening-detected, 0.3% were mammographic screening-detected and others were identified through clinical breast examination (CBE) (1.0%) or chest CT/MRI (1.6%). Detection by screening was associated with earlier stages of breast cancer compared to self-detection, yet, 32.2% of self-detected diseases were at stage 0-I. A total of 166 (53.5%) patients had a screening history, with ultrasonography being mostly used and provided by employers. Leading self-perceived barrier to breast cancer screening was lack of awareness, followed by lack of access. And screening participation was associated with a younger age, higher education, being currently working, residence in urban area, and a high family income. Conclusions: Self-detection still remains a major way of breast cancer detection in Beijing, but it is not necessarily associated with a late-stage disease. The suboptimal screening rate with disparity in screening behavior can be mostly attributed to lack of awareness of the public and insufficient screening providers.
