Bowel (colorectal) cancer

There were 1,155 cases of bowel cancer (colorectal) diagnosed in Northern Ireland in 2017. Bowel cancer is one of the most common cancers in Northern Ireland. Bowel cancer is more common in older people, especially men.

Signs and symptoms

Symptoms of bowel cancer can include:

• blood in your poo

• looser poo, pooing more often and/or constipation

• a pain or lump in your tummy

• feeling more tired than usual for some time

• losing weight for no obvious reason

Please remember that these symptoms don’t necessarily mean that you have bowel cancer. But if you have any of these symptoms for 3 weeks or more, please speak with your GP. It is important to do this even if you have recently had bowel cancer screening and/or a colonoscopy.

Screening for bowel cancer

Regular cancer screening is important. Screening can detect certain cancers before you have any symptoms. Finding cancers early means that treatment is likely to work best. In Northern Ireland, the Public Health Agency runs a screening programme for bowel cancer. The programme offers screening every two years to all people aged 60 to 74.

Bowel cancer screening uses a home test kit to look for unseen traces of blood in the bowel motions. Blood in the stools can be a sign of bowel cancer so further tests can then be carried out. Screening can also find polyps in the bowel, which are abnormal growths of cells that may develop into cancer later if they are not removed. The aim of bowel cancer screening is to detect bowel cancer at an early stage (in people with no symptoms) when treatment is more likely to be effective.

The test used within the bowel cancer screening programme has recently changed. The new test is called a Faecal Immunochemical Test (FIT). This test is easier to use and is better at detecting individuals who require further investigations.
