<![CDATA[Abstract: Breast cancer patients often come to the doctor diagnosed at a locally advanced stage. The cause of delay in treatment is influenced by predisposing factors, namely knowledge, family history, education level, attitude, action to seek health facilities, fear, and family income. The study aimed to analyze the relationship between predisposing factors and the delay in treatment of locally advanced breast cancer patients. The study used an analytic observational method with a cross sectional approach. The study respondents were 51 patients with locally advanced breast cancer who sought treatment at the Oncology Surgery Polyclinic and were recorded in the medical records of RSUD Ulin Banjarmasin for the period January 2020-November 2023. Data were collected based on a questionnaire of predisposing factors for delay in treatment. Data analysis used Fisher's test on SPSS and was said to have a significant relationship if p < 0.05. As a result, the majority of respondents were in the inoperable category 96.1% with poor knowledge (84.3%; p=0.022), low education level (51%; p=1), no family history (56.9%; p=0.5), poor attitude (92.2%; p=0.152), poor action to seek health facilities (90.2%; p=0.188), fear of symptoms (82.4%; p=0.152), and low family income (60.8%; p=1). In conclusion, there was a significant association between knowledge and delay in seeking treatment for locally advanced breast cancer patients. Meanwhile, the level of education, family history, attitude, action to seek health facilities, fear and family income did not have a significant relationship with the delay in treatment of locally advanced breast cancer patients.
