In 2013, the risk of being diagnosed with colorectal cancer by age 85 was one in 13.34 The risk markedly increases from age 45.8
In 2013, there were 14,962 new cases of colorectal cancer.34 In 2014, there were 4,071 deaths from colorectal cancer, accounting for 9.2% of all cancer deaths in Australia.34
At the end of 2012, there were 52,630 people living who had been diagnosed with colorectal cancer in the previous five years (from 2008 to 2012).35
In women, it was the third most prevalent cancer, with a prevalence of 23,581 women diagnosed in the past five years.35
Five-year relative survival from colorectal cancer for diagnoses in 2009-2013 was 68.1% for males and 69.4% for females.35 This was a significant improvement compared with survival statistics from 1982-1986 (48% for males, 50% for females).10
In the period 2006 – 2010, there were some significant disparities in five-year relative survival from colorectal cancers based on regional differences and socioeconomic status, including:10
- higher survival (67%) for individuals in major cities compared with individuals in inner regional (65%) and outer regional (63%) areas
- higher survival in individuals in the highest socioeconomic status quintile (69%) compared with those in the three lowest socioeconomic status quintiles (65% or 66%).
Access Cancer in Australia: an overview 2017(PDF, 3.7MB)35 and summarise information to distinguish between cancers of the small intestine, colon, and rectum on the following criteria:
- projected incidence in 2017
- risks by age 75, and by age 85
- annual change in incidence and mortality between 2012 and 2017 (projected)
- trends in five-year survival.
Access Cancer survival and prevalence in Australia: period estimates from 1982-201010, and compile information to compare colorectal cancer and other common cancers on the following criteria:
- cancer survival and prevalence in Australia: period estimates from 1982-2010 relative five-year survival rate for colorectal cancer
- prevalence of colorectal cancer
- trends in survival from colorectal cancer.
Access the American Cancer Society’s Colorectal Cancer Facts and Figures 2014-2016 (PDF, 1.41MB)11 and review the table on page 3 outlining colorectal cancer incidence and mortality in America from 2006-2010. Then, access the equivalent Australian data by going to the AIHW’s Australian Cancer Incidence and Mortality books34 and selecting ‘bowel cancer’; open the summary section for 2013.
- Data on incidence and mortality rates are presented as ‘age standardised rates per 100 000 people’. What does this term mean? (You might find a site like the AIHW’s Metadata Online Registry13 helpful).
- Looking at the data for both countries, identify the similarities and differences between incidence and mortality rates for males and females.
