Cancer incidence and survival by subsite
Cancer groups within the Cancer data in Australia report are generally defined using the International Classification of Diseases 10th Revision (ICD-10). In many instances, the cancer sites reported have subsite information. The following incidence and survival data visualisations provide the subsite information for each of the cancers.
Not all cancers more commonly reported on within this report have subsite information. For example, rectal cancer identifiable with ICD-10 code C20, has no more detailed subsite information. Colon cancer, identifiable with ICD-10 code C18 has subsite data including the caecum (C18.0), appendix (C18.1), ascending colon (C18.2), hepatic flexure (C18.3), transverse colon (C18.4), splenic flexure (C18.5), descending colon (C18.6), sigmoid colon (C18.7) and overlapping lesion of colon and colon unspecified (C18.8 and C18.9).
Note: Some cancer incidence projections have changed more considerably from the 2024 report estimates
The AIHW projects cancer incidence, mortality and prevalence to estimate counts and rates for the years where complete national data are not yet available, based on trends for the previous 10 years (for example, 2012–2021). Each year, AIHW updates the projections and includes a new year of data. In this release, actual data from 2020 and 2021 (during the COVID-19 pandemic) have been included in the projections for some cancers for the first time. Because of this, changes to estimates for previous years are greater than usual for some cancers, including (but not limited to) breast cancer, melanoma of the skin, colorectal cancer and colon cancer. For further information, please see the Methods section.
Cancer incidence rates and counts by 4-character ICD-10 subsite data visualisation
Figure 1 of this visualisation shows incidence rates by age time series for the selected cancer subsite. Figure 2 shows the time series of percentages that the subsite is of the selected cancer. Rates and percentages are available for different age groups and overall. The visualisation contains information on many different cancers and subsites. Data is available by sex. The data for this visualisation is available in Excel workbooks in the Data section of the Cancer data in Australia report.
Cancer incidence by subsite data are available as supplementary tables.
Cancer survival by subsite
The number of subsites available within the cancer by subsite survival visualisation is less than incidence. Incidence data is provided if there is at least one case in the years reported while survival rates are provided if there is a survival rate for at least one of the reporting periods. Reliable survival rates require considerably more cases.
In addition to the 5-year reporting periods, a 15-year reporting period (2007–2021) has been created to increase the likelihood of at least a limited range of survival statistics being available for rarer cancers. This period provides only a limited understanding of survival. A limitation of this period is that the rates may be more predominantly derived from earlier years where survival may differ compared to more recent periods.
Cancer survival by ICD-10 subsite data visualisation
Figure 1 show the survival for the selected subsite over time. Figure 2 shows the survival rates by age for the selected subsite for a selected period. Figure 3 shows the number of cases by age for the selected subsite. Survival rates include either relative or observed. Survival rates include 1, 2-, 3-, 4- or 5-year survival. Data is available by sex. The data for this visualisation is available in Excel workbooks in the Data section of the Cancer data in Australia report.
Cancer survival by subsite data are available as supplementary tables.
