Background: Patient delay commonly appears in breast cancer (BC), but the findings for influential factors may be contaminated by recall bias. The real factors in patient delay (divided into appraisal delay and utilization delay) for women with BC urgently need to be objectively analyzed for preventing the progression of this disease. Methods: Women meeting strict inclusion and exclusion criteria were asked to fill in a questionnaire, which included three sections of sociodemographic characteristics, medical history, and knowledge of BC. Later on, the outcomes were processed according to the verification of BC by pathological diagnosis. Then, multiple linear regression was conducted to analyze the potential factors of the delay and to explore their relations between these factors and BC. Results: Appraisal delay is the leading component of patient delay. Appraisal delay's time distribution of a higher percentage at delay time 0-29 and >360 days, while other delay time occupies lower percentage, which is highly consistent with that of patient delay, while utilization delay mainly occurs in the 0-29 days period. Concerning the influential factors for the different phases of delay, age (P=0.051, P=0.035 separately in appraisal and patient delay), residential address (P=0.036, P=0.010) and symptom disclosure to others (P=0.015, P=0.015) led to a decrease of appraisal and patient delay. However, reasons for first medical consultation (P=0.033, P=0.006) and knowledge of BC (P=0.027, P=0.002) would accelerate appraisal and patient delay. Many factors related to hospitals, such as hospital category for first medical consultation (P=0.030) and examinations for first medical consultation (P=0.055) would reduce utilization delay. Conclusions: Obstacles in medical consultation for younger women should be removed, and early interventions are needed to avoid progression of BC.
