Screening for Colorectal Cancer
Screening represents an alternative possibility of influencing the mortality of colorectal cancer in a population. It may reduce mortality in two ways. Firstly by the detection of tumours early in their natural history before they have produced symptoms and when the tumour is amenable to surgical treatment and secondly, by the detection and removal of premalignant adenomas with a resulting decrease in the future incidence of colorectal cancer.
