The prevalence of lymph node involvement was 15.8 % (48/304). In the crude and adjusted analysis, factors associated with lymph node involvement were lymphovascular invasion (adjusted OR 9.32; 95 % CI 4.27-21.15) and myometrial invasion (adjusted OR 3.95; 95 % CI 1.29-14.98). Of the patients undergoing lymphadenectomy, 15 % have lymph node involvement. Less invasive diagnostic options than radical surgery to ascertain lymph node invasion should be assessed. Of the patients undergoing lymphadenectomy, 15 % have lymph node involvement. Less invasive diagnostic options than radical surgery to ascertain lymph node invasion should be assessed. To determine the association between delayed diagnosis and advanced clinical stage breast cancer, and to explore the factors that influence this delay. Cross-sectional study of women over 18 years of age with breast cancer who attended 4 oncology centers in Medellín, Colombia, in 2017. The "Breast Cancer Delay Questionnaire" which includes sociodemographic and clinical variables as well as time intervals was used. Crude and adjusted odds ratio (OR) were estimated, using advanced clinical stage as outcome and delayed diagnosis as exposure. 42 patients were included. The median time interval between the identification of the problem and the diagnostic biopsy was 104.5 days; between the identification of the problem and the first medical visit, 20 days; and between the first visit and the diagnostic biopsy, 53 days. Of all the cases, 52.1 % were diagnosed at an advanced stage. An association was found between delayed diagnosis and advanced clinical stage (OR = 2.15 95 % CI 1.21-3.79). Age above 40 was founys in treatment after the diagnosis of breast cancer, and to assess interventions designed to reduce delays in the care of this form of cancer. An accurate, automated, an
