Understanding the diagnosis

One of Bowel Cancer UK's main aims is to raise awareness of bowel cancer symptoms and to encourage people to take part in the screening programmes currently rolling out around the UK. However, anyone with symptoms, even if eligible for screening is advised to see their GP.

Your GP will want to take a full history from you (see the factsheets Keeping a Symptom Diary; Talking to Your GP) and may wish to carry out some preliminary tests. These might include:

  • Rectal examination and/or abdominal examination
  • Blood tests
  • Faecal occult blood test


If your symptoms and/or risk factors suggest further tests are necessary you will be referred to your local hospital. Common investigations include:

  • Colonoscopy
  • Flexi-sigmoidoscopy
  • CT/MRI scan
  • Virtual Colonoscopy (this test is usually conducted privately)


Less common investigations include:

  • Barium enema
  • Ultrasound

People with suspected cancer are usually seen at the hospital within 2 weeks of referral from GP.


Please download the factsheet How Bowel Cancer is Diagnosed to find out more about these investigations and tests.
