28 patients suffering from colon cancer were treated and operated on at the Department of Surgery, General Hospital in Nova Gradiška in the period January 1985 to June 1987. The frequency and intensity of bleeding from the colon cancer were examined. Preoperative minimal bleding was found with 20 patients (71.5%). More abundant bleeding was diagnosed with only one patient, or in 3.5% cases. Urgent surgical operation because of colon cancer bleeding was not necessary in any of the cases. Minimal bleedings are characteristics for colon cancer. Every colon bleeding requires radiological and endoscopic examination of the colon.
