Bowel Cancer Screening

Bowel cancer screening is a home testing programme that helps detect bowel cancer at an early stage, often before symptoms develop. It uses a Faecal Immunochemical Test (FIT) to check for tiny amounts of blood in a stool sample. 

  • People aged 50 to 74 years who are registered with a GP and live in England are automatically invited for screening every 2 years
  • People aged 75 and over can request a FIT kit every 2 years by calling the NHS Bowel Cancer Screening Helpline on 0800 707 60 60
  • A FIT kit is sent to the patient’s home.
  • The patient collects a small sample of stool (poo).
  • The sample is returned by post to a laboratory.
  • The laboratory checks for hidden blood that may indicate bowel cancer or bowel polyps.

Normal result

  • No further action is needed.
  • Another FIT kit will be sent when the patient is next due for screening. 

Abnormal result

  • Blood has been detected in the sample.
  • This does not necessarily mean the patient has cancer.
  • The patient will usually be offered an appointment to discuss further investigations, commonly a colonoscopy
  • Bowel cancer is one of the most common cancers in the UK.
  • Screening can identify cancers earlier, when treatment is more effective. 
  • Screening may also find bowel polyps, which can be removed before they develop into cancer.
