Bowel Cancer

Did you know?

  • Bowel cancer is the second most common cancer affecting both women and men in Western Australia.
  • In 2017, 702 Western Australian men and 605 Western Australian women were diagnosed with bowel cancer.
  • Bowel cancer is also known as colorectal cancer (cancers of the colon and rectum).

Common symptoms of bowel cancer include:

  • Blood in your poo (once or more)

Or, for more than four weeks:

  • A change in your normal bowel habit, such as runny poo, pooing more often or finding it hard to poo
  • A new pain, lump or swelling in your tummy
  • Feeling tired or looking pale
  • Losing weight without trying
  • Not feeling hungry.

If you have noticed any blood in your poo or evidence of bleeding from your back passage (red or black blood), even if it was just once, it’s important to tell your doctor, clinic nurse or Aboriginal health worker straight away.

If you have had any of the other symptoms for more than four weeks, tell your doctor, nurse or health worker. It doesn’t mean you’ve got bowel cancer – often these symptoms turn out to be something less serious. But it’s important to tell your health professional and get checked out to be safe.

If it is bowel cancer, the earlier it’s found, the greater the chance of successful treatment.
