[The hemoccult test in the screening for colonic carcinoma]

The only practicable method for mass screening for carcinoma of the colon is detection of occult blood in stool. In a coloscopically controlled study with the Haemoccult test, dependent from diet, 54-66% of polyps and 77-100% of carcinomas were detected. The Haemoccult test is therefore a suitable method for mass screening for colon carcinoma.
