Colorectal cancers have few to no symptoms at an early stage. In the later stage, some symptoms may include:

  • Blood in stools
  • Change in bowel habits
    • Diarrhoea
    • Constipation
    • Change in the consistency of stool
  • Abdominal pain or discomfort
  • Anaemia
  • Weakness or fatigue
  • Lump in the abdomen
  • Unexplained weight loss

The symptoms will vary depending on the cancer’s size and location. If you are experiencing any of these symptoms, it is important that you see your doctor.
