Bowel Cancer Australia recommends participating in screening appropriate to your personal level of risk.
For people at average or near average risk* of bowel cancer, Australian medical guidelines recommend screening using a faecal immunochemical test (FIT) every 2 years between ages 50-74.
The guidelines also state GPs can offer a faecal immunochemical test every 2 years to people aged 45-49 who request it, after being fully informed of the benefits (and any possible harms) of testing.
In May 2021, the US Preventive Services Task Force (USPSTF), recommended screening start at age 45. People aged 45 to 75 should be screened to reduce their risk of dying from bowel cancer. For adults agd 76 to 85, the Task Force continues to recommend that the decision to screen be made on an individual basis.
In March 2021, the American College of Gastroenterology (ACG) published updated clinical guidelines, which recommend screening start at age 45 for people of average risk to reduce incidence and death from bowel cancer as well as incidence of advanced adenoma.
In May 2018, the American Cancer Society changed its screening guidelines to recommend lowering the starting age for people at average risk of bowel cancer from 50 to 45 years in response to the rising rates of bowel cancer in young and middle-aged populations. The updated guidelines also state for people aged 76-85, the decision to be screened should be based on a person's preferences, life expectancy, overall health, and prior screening history.
* People with (i) no first- or second-degree relative with bowel cancer; or (ii) one first-degree relative with bowel cancer diagnosed at 55 years or older; or
(iii) one first-degree and one second-degree relative diagnosed with bowel cancer at 55 years or older

At-home bowel screening involves a test that looks for very small amounts of blood in poo that is non-visible to the naked eye in people who do not have any obvious symptoms of bowel cancer.
The at-home bowel screening test is called a faecal immunochemical test (FIT).
Screening using a faecal immunochemical test is one of the most effective ways to reduce the risk of dying from bowel cancer. The test can detect blood in poo caused from pre-cancerous polyps or from early stage bowel cancer. The test however does not detect bowel cancer itself.
When identified early, almost 99% of bowel cancer cases can be successfully treated.
The faecal immunochemical test involves collecting toilet water or poo samples, placing them on a card or in a container, and mailing them to a pathology laboratory for analysis. The results are then sent back to you and your GP.
A positive test result means blood in poo has been detected. If blood is detected, you should contact your GP immediately to discuss the result and obtain a referral for further investigation via colonoscopy within 30 days.
The presence of blood in poo may be due to conditions other than bowel cancer, such as medications, polyps, haemorrhoids, or inflammation of the bowel, but the underlying cause of the bleeding needs to be investigated by colonoscopy. During the procedure, any polyps can be identified and removed or a diagnosis of bowel cancer confirmed.
A negative test result means blood in poo has not been detected and it is recommended that you repeat the test every 2 years.
However, this does not mean that you do not have, or can never develop, bowel cancer, since some bowel cancers do not bleed or only bleed on and off. In between times, if you develop any symptoms of bowel cancer, see your GP immediately.
| Screening tests have risks
Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your GP or pharmacist. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer.
False-negative test results can occur
Screening test results may appear to be normal even though bowel cancer is present. A person who receives a false-negative test result (one that shows there is no blood in poo when there really is) may delay seeking medical care.
False-positive test results can occur
Screening test results may appear to be abnormal even though no blood in poo is present. A false-positive test result (one that shows there is blood in poo when there really isn't) can cause anxiety and is usually followed by more tests (such as colonoscopy), which also have risks.
