How do I get tested for bowel cancer?
If you are experiencing any bowel-related symptoms, book an appointment to see your GP as soon as possible.
Symptoms of bowel cancer can be very similar to other bowel-related conditions, however, it’s important to diagnose what is causing these symptoms. If it is cancer an early diagnosis can make all the difference to successful treatment.
Your GP will ask about your symptoms and check whether you have a family history of bowel cancer. They will assess your symptoms and carry out some initial examinations, they may also refer you for an initial blood test.
After these initial examinations if your symptoms could be bowel cancer then your GP will refer you to a consultant or hospital for further investigations. Most people referred for further tests will not have cancer, but an early diagnosis can lead to more successful treatment outcomes if it is cancer, so don’t delay in seeking medical advice.
Tests to help diagnose bowel cancer

What is a virtual colonoscopy?
A CT scanner is used to produce images of the large bowel and rectum. This type of colonoscopy can identify growths such as polyps or changes to the shape of the bowel.
However, it doesn’t provide the same level of detail as a flexible sigmoidoscopy or colonoscopy, and samples or polyp removal cannot take place at the same time, so further tests or treatment may be required.

What is a video capsule endoscopy?
Video capsule endoscopy is an innovative way of looking at the inside of your bowel, by swallowing a small disposable camera the size of a large pill.
Dr Adam Humphries, Consultant Gastroenterologist at London Digestive Health explains more about how this test works.
What happens next?
Your consultant will discuss any further diagnostics with you in more detail and arrange a time for these to take place. Sometimes these can even be arranged on the same day. Our team of Clinical Nurse Specialists will be available to support you.
