A reduction of the high mortality figures from colorectal cancer is possible only when early diagnosis is achieved. This is the aim of annual screening of asymptomatic persons starting at age 45. The only practicable and effective screening method at present is searching for occult blood in feces with the Hemoccult-test. This test should therefore be part of the routine laboratory programme.
