The bowel cancer journey

Bowel cancer, also called colorectal cancer, is the second most common cancer in both men and women in Australia (1). Eighty per cent of cases have no known hereditary genetic associations. More than 15,000
bowel cancers were diagnosed in Australia in 2012, and in the same year almost 4,000 people died from the disease.

Bowel cancer is preceded by polyps, which may become invasive cancer if undetected.

What is a polyp?
A polyp is a small stalk-like protrusion of tissue that grows out of the membranes lining various areas of the body.

Polyps can be adenomas, of which a small percentage can turn malignant given time, or hyperplastic polyps which are usually harmless unless they contain an adenoma.

The exact cause of intestinal polyps is unknown, but diet, lifestyle and genetics are all thought to contribute.

Most colorectal polyps have no symptoms, but possible symptoms can include:

  • Blood in the faeces
  • Clear mucus in the faeces
  • Diarrhoea or constipation
  • Abdominal pain

Rectal bleeding can also be caused by haemorrhoids, which are varicose veins in the rectum or anus. It is still important to see a doctor if you notice bleeding, however, to rule out cancer.

Oncologist Sanjay Mukhedkar from OncologyWest says bowel cancer is still a disease of the elderly although if you have a family history of bowel cancer, you should get some genetic testing done.

“If it’s in your family, have some genetic tests or have an early colonoscopy.”

Bowel Cancer Screening
A faecal immunochemical test (FIT) is a screening test that can detect small amounts of blood in your faeces. The test looks for blood, not for bowel cancer itself.

You can do the FIT at home by placing small samples of faeces on special cards and sending them to a pathology laboratory for analysis. The results are then sent back to you and your doctor.

If you are over 50 years old, you may be eligible for the Australian Government’s National Bowel Cancer Screening program – check your eligibility by calling 1800 118 868 or visit www.cancerscreening.gov.au.
For those not eligible for the government’s screening program, BowelScreen Australia® also provides bowel cancer tests available for purchase online or at your local pharmacy.
Visit www.bowelscreenaustralia.org/ screening or speak to your GP.

Bowel Cancer Australia has created an app that provides information on bowel cancer, such as healthy lifestyle changes you can make and a treatment diary for those already being treated for the disease.
