Most bowel cancer is seen in the large bowel or the rectum (back passage).

What are the symptoms of bowel cancer?

You should see your GP if you notice any changes in your normal bowel habits that continue for more than three weeks. These include:

  • Diarrhoea
  • Constipation
  • Frequency of passing stool

Other symptoms may include:

  • Persistent pain in your abdomen
  • Blood in your stool or bleeding from your rectum 
  • Unexplained weight loss
  • Vomiting
  • Feeling bloated
  • A lump in your abdomen

These symptoms may indicate another condition. It’s a good idea to get checked - caught early bowel cancer can be successfully treated.
