What are the key bowel cancer symptoms and does a screening test hurt? Find out what you need to know about one of the most common cancers in the UK.

To mark the launch of Vitality’s bowel cancer home screening test (coming soon), health journalist Carole Beck asked Dr Dawn Richards, Medical Affairs Director at Vitality, for answers to some of the most common concerns around preventing the disease and the signs of bowel cancer to look out for.

1. What is bowel cancer?

Bowel cancer is a form of cancer that starts either in the large bowel – also known as the colon or large intestine – or the rectum. It’s the fourth most common type of cancer in the UK.

2. What’s the difference between bowel and colon cancer?

Colon cancer is actually a subgroup of bowel cancer. It simply means cancer of the large bowel or the colon.

3. Who is most likely to get bowel cancer and is it hereditary?

It’s not yet been discovered exactly what causes bowel cancer, but certain factors do make you more likely to develop it, including:

  • Your age – people 50 years or older are more at risk
  • A family history of bowel cancer – particularly in a parent or sibling younger than 50
  • Having another bowel disease, such as Crohn’s disease
  • Eating processed meat and a lot of red meat
  • Lynch syndrome – this genetic condition increases your risk of developing bowel cancer
  • Smoking or drinking alcohol to excess
  • Lack of exercise.

4. How can we prevent it?

You can’t alter your age or family risk of bowel cancer, but these lifestyle changes can reduce the risk of developing the disease:

5. What are the common signs of bowel cancer?

Most people with bowel cancer have a combination of the following symptoms:

  • Blood in the stools
  • Rectal bleeding
  • A persistent change in bowel habit lasting more than 2-3 weeks – for example, going to the loo more often and having looser stools
  • Unexplained weight loss
  • Anaemia
  • A lump or pain in your stomach
  • Fatigue

If you have one or more of the above symptoms for more than four weeks, visit your GP.

6. How do you test for it?

A home bowel cancer screening test

This tests for traces of blood in your stools, so can detect early-stage bowel cancer and also polyps, which may turn into cancer. Vitality will soon offer home bowel cancer screening tests as part of your health insurance.

The NHS also offers home bowel cancer screening tests every two years for people in England, Wales and Northern Ireland aged 60-74 years and people in Scotland aged 50-74 years.

Hospital tests

If you are experiencing bowel cancer symptoms or your home screening test has detected blood, your GP will refer you for further tests, usually a bowel scope or colonoscopy. One-off bowel scope tests from the age of 55 are also offered in certain areas of England.

7. Is it difficult to do a home bowel cancer screening test?

No. Vitality sends you the FIT screening kit (Faecal Immunochemical Test), which just involves taking a single sample of your stool and posting it back to the laboratory for testing.

If you are testing via the NHS, people living in Scotland receive the FIT test, too. However, in England, Wales and Northern Ireland, the FIT is still to be phased in – instead you may receive a different screening test called the faecal occult blood test (FOB), which needs three separate stool samples over a two-week period.

Whichever kit you receive, you’ll receive clear instructions on how to use it.

8. Does a bowel cancer test hurt?

The home screening test doesn’t hurt at all. The bowel scope and colonoscopy can be a little uncomfortable, but they shouldn’t be painful.

9. What happens after my screening test?

You’ll receive your results within a few weeks. If blood is found in your stool, you’ll need to see your GP, who may refer you to hospital for further tests, usually a colonoscopy, which involves inserting a tube with a camera into your bowel.

If your test comes back negative, you don’t need to do anything – just take another test in two years.

Vitality’s at home bowel cancer screening tests will be coming soon.
