Notes on the data: Premature mortality by selected cause - 0 to 74 years

Deaths from colorectal cancer, persons aged 0 to 74 years, 2016 to 2020

 

Policy context:  Colorectal cancer refers to cancer of the colon, rectum and anal canal and is more commonly referred to as bowel cancer [1]. Most bowel cancers are thought to develop from non-malignant growths on the lining of the wall of the bowel. These non-malignant growths are called adenomas or polyps. While the causes of bowel cancer are not fully understood, there are a number of factors associated with the risk of developing the disease. These factors include: increasing age; a personal history of bowel cancer or polyp; a family history of bowel cancer, adenoma or gynaecological cancer; and a personal history of inflammatory bowel disease [1].

In 2012, bowel cancer was estimated to account for 13% of the burden of disease due to cancer in men, and 12% of the burden of disease due to cancer in women in Australia [2].

Age-standardised mortality rates for colorectal cancer increased from 1968 (31.1 per 100,000 population) to 1985 (32.8 per 100,000 population ), after which they decreased to 18.7 per 100,000 in 2016 [3]. The trends were similar for males and females, although the male rate in 2016 was 47.4% higher than the female rate [3].

For 2016 to 2020, 46.4% of all deaths from colorectal cancer were premature – details here.

For deaths data released since 2007, the Australian Bureau of Statistics (ABS) has applied a staged approach to the coding of cause of death which affects the number of records available for release at any date. In general, the latest year’s data is preliminary, the second latest is revised and the data for the remaining years is final. For further information about the ABS revisions process see the following and related sites: http://www.abs.gov.au/ausstats/abs@.nsf/Lookup/3303.0Explanatory+Notes12012.

However, data published here are from the following releases: 2016 and 2017, final; 2018, revised; and 2019 and 2020, preliminary.
