Bowel (colorectal) cancer is the 3rd most common cancer in the UK and the 2nd most common cause of cancer related death - 16,000 people die from bowel cancer each year. The UK NHS Bowel Cancer Screening Programme recommends colonoscopy for the examination of the colon in men and women from the age of 60 years with a positive faecal occult blood test (FOBT). In the USA, a colonoscopy to check for bowel cancer or polyps is offered from the age of 50 years without the need for an FOBT.

Colonoscopy can detect bowel cancer at an early stage and before symptoms develop, significantly improving the chance of recovery and long term survival. As most bowel cancer is believed to come from polyps, colonoscopy can also prevent cancer by removing polyps when these are found.

Colonoscopy is also recommended for surveillance of certain patients who are at increased risk of bowel cancer. This includes those with:

  • a family history of bowel cancer
  • a personal history of colonic polyps or bowel cancer
  • a genetic predisposition
  • inflammatory bowel disease

Special techniques can be applied during colonoscopy to improve detection of the pre-malignant changes that occur before cancer develops.

Patients with the following symptoms or signs should also consider a colonoscopy:

  • a change in bowel habit
  • chronic diarrhoea
  • rectal bleeding
  • unexplained iron deficiency anaemia
