The early recognition of carcinomas is also in the abdominal region the aim of our permanent effort in the improvement of the prognosis of this disease. Only by a timely diagnosis a permanent cure is possible. Endoscopy and radiology are the corner-pillars of the diagnostics. At the least suspicion of a tumorous disease these methods should be used with all consequence. Since the methods mentioned cannot be used as mass examinations the control of risk groups are of great importance. In these groups of patients an actual care is possible.
