Free prophylactic colonoscopy performed in Poland since 2000 as part of the National Program for Combating Cancer Diseases, is characterized by low reporting rates. Therefore, a study was carried out to understand the medical circumstances immediately preceding the diagnosis of colorectal cancer in the Katowice agglomeration, with particular emphasis on the role of screening colonoscopy. <br \/><strong>MATERIAL AND METHODS.<\/strong> The questionnaire study included 96 patients with colorectal cancer. The socioeconomic status, knowledge about prophylaxis, individual disease history, including diagnostic procedures, and participation in the population screening program were assessed. <br \/><strong>RESULTS.<\/strong> In the case of patients hospitalized in the Katowice agglomeration in 2019-2022, the diagnosis of colorectal cancer occurred most often as a result of the patient visiting a doctor due to disturbing gastrointestinal symptoms (56.3% of cases). 36.4% of cases were diagnosed by a physician during a visit for reasons other than suspicion of cancer. Participation in the free screening program (colonoscopy) accounted for 6.3% of the circumstances in which the disease was detected. <strong>CONCLUSIONS.<\/strong> The most common diagnosis of colorectal cancer was performed by the patient visiting a doctor due to disturbing symptoms from the digestive system. The mean age of the patients diagnosed with the disease as a result of reporting to a physician due to alarming symptoms was 3 years greater than the age of patients diagnosed during the screening colonoscopy.<\/p>\n<p><strong>WST\u0118P.<\/strong> Rak jelita grubego jest w Polsce trzeci\u0105 najcz\u0119stsz\u0105 przyczyn\u0105 zgon\u00f3w z powodu nowotwor\u00f3w.
