FAECAL DNA TESTING
Faecal DNA testing
Clinical accuracy data on faecal DNA tests is still too limited to support population screening. However, molecular tests offer hope for the future of risk-free screening tests.
National recommendations United Kingdom
The NHS Bowel Cancer Screening Programme http://www.cancerscreening.nhs.uk/bowel/ offers screening every two years to all men and women aged 60 to 69 by faecal occult blood testing. Around 2 in 100 people will receive an abnormal result. They will be referred for further investigation and usually offered a colonoscopy. For a population of patients >50 years undergoing screening colonoscopy 5-6% can be expected to be found to have cancer or an advanced colonic polyp (an abnormal growth of tissue).
