title: Detecting early colon cancer.
abstract: Techniques enabling detection of early colon cancer already exist, but to be more productive in terms of improving survival they must be applied in a meaningful sequence and repeated regularly in high-risk patients. Positive findings in specific screening steps based on well-known risk factors in colon cancer always call for aggressive follow-up. The advantages and disadvantages of the various techniques are discussed.
