Colonoscopy Screening

We strongly encourage screening, as 1 in 19 of us develop colon cancer. Colon cancer deaths can be reduced by at least 75%-80% by colonoscopy screening. We predominantly use the excellent team at the London Clinic and we advise all patients over 50 to have a colonoscopy every 10 years. Colon cancer nearly always starts from a precancerous polyp, and there is usually a long phase-lag from when polyps are visible at colonoscopy to the later development of cancer. Hence it is an ideal area for screening. If potentially precancerous polyps are found they can usually be simply removed at the time, and then a repeat colonoscopy will be advised in 3 to 4 years’ time.

(Sadly the NHS is not in a financial position to offer everyone colonoscopy screening. The current campaign, based on checking stools for blood, has only been shown to reduce the mortality of colon cancer by 14 %.)
