Bowel Cancer Screening

What is cancer screening? – Screening is where you are checked for a disease even if you don’t have any symptoms. It is an important way in which serious conditions can be identified and treated before symptoms are present. If cancer is detected early then treatment is often more successful and long-term risks to your health are significantly reduced. Of the GI cancers, screening is available for bowel cancer.

    Why Do We Screen for Bowel Cancer
    • Screening gives you peace of mind if nothing unusual is discovered.
    • Detects the early signs of bowel cancer so you can begin treatment quickly.
    • Highlights anything that needs to be monitored, such as a finding of pre-cancerous growths (polyps).
    • The NHS carries out bowel cancer screening for anyone over the age of 55. However, the risk of bowel cancer increases after the age of 45.

     

    If you are higher risk or would like to take a preventative approach to your health, then consider private bowel cancer screening.

     

    Higher risk people include:

    • Over 50 years of age – 90% of bowel cancer cases are in over 50 year olds.
    • Over 60 years of age – 80% of bowel cancer cases are in over 60 year olds.
    • Family history of colon polyps or bowel cancer.
    • Family history of Lynch Syndrome – this type of colon cancer runs in families and tends to cause cancer from a younger age (under 45 years old).
    • If you are experiencing any bowel cancer-related symptoms.
    • Those with longstanding Inflammatory Bowel Disease (IBD) e.g.Crohn’s disease or ulcerative colitis.

    Bowel Cancer Screening Test

    Bowel cancer screening procedures look inside the colon for growths on the bowel wall, called polyps. Some colonic polyps are non-cancerous and will remain so, but others have the risk of developing into cancer, which can grow and spread to other organs. Screening will be taken by one of the following tests:

    Stool Test

    A simple assessment of your stools can show signs of bowel cancer, such as blood, or abnormal DNA. Blood may not necessarily mean that you have bowel cancer, however, if the doctor sees anything unusual, they will refer you for a colonoscopy.

    Flexible Sigmoidoscopy

    A flexible sigmoidoscopy procedure is used to check for bowel cancer in the last part of the colon and the rectum, passing a flexible camera (on a thin agile tube) up through the back passage. An enema is needed prior to the procedure. When necessary a biopsy (tissue sample) can be taken, or a polyp can be entirely removed.

    Colonoscopy

    The colonoscopy is a similar to the sigmoidoscopy but allows us to assess the entire length of the colon. It requires laxatives prior to the procedure so that clear views are obtained. A thin, agile tube with a camera and bright light, called a colonoscope, is inserted into the back passage and can work all the way up to the top of the colon and back down again, whilst projecting images onto a screen for the doctor to see. It is the best examination for bowel cancer and if any other prior test shows anything unusual, then a colonoscopy is usually needed. Sometimes patients just opt for a colonoscopy in the first instance to ensure that results are the most accurate available.

    CT Colonoscopy

    The “virtual” colonoscopy uses a CT scan to assess the colon. It is an effective, non-invasive test to spot bowel polyps and signs of cancer. However, it has limitations as small polyps hide in the many twists and turns on the colon, which can get missed when assessment is made via a scan.
