Colorectal Cancer

What are the symptoms of colorectal cancer?

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 should you 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.
