Colorectal Cancer - Symptoms

In the early stages, colorectal cancer may not cause any symptoms. In later stages, symptoms may include:

  • Persistent diarrhoea or constipation
  • Blood in the stools or rectal bleeding
  • Change in the consistency or calibre of stools
  • General abdominal discomfort (bloating, fullness, cramps or gas)
  • A feeling that the bowel does not completely empty after emptying the bowels
  • Constant tiredness
  • Severe appetite or weight loss

When to see a doctor

The symptoms above can be caused by a number of reasons and may not indicate the presence of cancer. However, make an appointment with your doctor if you have any signs or symptoms that worry you.
