The detection of colorectal polyps is of critical importance in the prevention of colorectal cancer. Studies have demonstrated that colorectal cancer arises from colorectal polyps in more than 95% of cases. Fortunately most polyps do not become malignant (less than 1%) and it is known that less than 5% of all colonic adenomas harbour malignancy. The National Bowel Cancer Screening Program has been a government initiative to assist in the detection of early cancers and malignant polyps through the detection of occult haemoglobin in stool and some larger clinical trials have demonstrated the benefits of screening population this way. Once a malignant polyp is determined colonoscopically a fresh set of questions arises in regards to best management practice.
