Endoscopic methods are a precious and valid tool for colorectal cancer screening; therefore they should be embraced if resources are available. The authors present a retrospective analysis of a Colorectal Cancer  Screening Unit during a 24 month period, using colonoscopy (76,1%)and flexible sigmoidoscopy (23,9%) envolving 2700 patients. Colorectal cancer was diagnosed in 1% of the patients and polyps in 38%, 16,1% of these had increased risk (size >1cm). Near eighty nine per cent of malignant neoplasic lesions and 71% of the polyps were located in the rectum and sigmoid cólon, therefore detectable by flexible sigmoidoscopy. These results support the implementation of endoscopic screening of colorectal cancer because of its diagnostic effectiveness and therapeutic possibilities (namely polipectomy). When resources are available, colorectal cancer screening should be preferably performed by colonoscopy and if not, by flexible sigmoidoscopy.
