Summary

Cancer is a major cause of illness in Australia and has a substantial social and economic impact on individuals, families and the community. Cancer data in Australia (CdiA) contains a wide range of cancer statistics. CdiA’s primary objective is making Australian cancer statistics accessible. We continue to expand the range of data within CdiA to meet the extensive cancer data needs and work continues in this space. The following pages are dedicated to helping you find out what is in the CdiA, what is new and where to find the data you need.

What's in this report?

CdiA provides a wide range of statistics on more than 70 cancers and data is updated annually. CdiA also includes some cancer data commentaries. Some of these commentaries are targeted articles focussed on specific cancers while others help people understand how to use CdiA’s data.

Most of the statistics within CdiA are presented through interactive data visualisations.  Data for all visualisations, except cancer rankings, are also available in Excel.

New content in CdiA for the 2021 release

An increased depth of cancer survival information on more than 70 cancers is available through the ‘Cancer survival by age data visualisation. The commentary ‘About age-adjusted survival rates’ focuses on age-adjusted cancer survival rates but also informs about the cancer survival by age data visualisation more generally.

The commentary ‘A different view of how brain cancer rates are changing over time suggests that some brain cancer statistics, while accurate, may not be providing a complete picture of how brain cancer rates are changing. The commentary highlights some issues and aims to provide a clearer picture of brain cancer rate changes over time.

The issues discussed within the commentary ‘Improving the understanding of ovarian cancer statistics are key for a more complete interpretation of how ovarian cancer rate changes over time. 

The data visualisations ‘cancer incidence by age’ and ‘cancer mortality by age provide cancer incidence and mortality rate time series for a wide range of different age groupings.  

Australian Cancer Incidence and Mortality (ACIM) workbooks have been reintroduced for 2021 for selected cancers.

CdiA core statistics (data updated June 2021)

The following statistics form the core CdiA content and are updated annually. The data visualisations mentioned within CdiA additional content will become CdiA core statistics in future releases.

What do the interactive data visualisations contain?

Describing trends for around 70 cancers, the cancer summary data visualisations contain:

  • the number of cancer cases diagnosed between 1982 and 2021
  • the rate of cancer cases diagnosed between 1982 and 2021
  • the number of deaths from cancer between 1982 and 2021
  • the rate of death from cancer between 1982 and 2021
  • rates of cancer cases and deaths, by age, between 1982 and 2021
  • 5-year relative survival rates for cancer, 1988–1992 period to the 2013–2017 period
  • the number of people alive as at December 31 2016 who have been diagnosed with cancer in the last year (in addition to the number of people in the last 5 years and 34 years)
  • Segi and World Health Organisation age-standardised incidence and mortality rates between 1982 and 2021

Please note that median/mean age at diagnosis and death have respectively moved to cancer incidence and cancer mortality age data visualisations.

The cancer rankings data visualisations contain the:

  • rankings of the top 20 cancers diagnosed, 1982 to 2021, in total and by age groups
  • rankings of the leading 20 cancers causing death, 1982 to 2021, in total and by age groups

Please note that ranking by age group has changed from 5-year age groups to 20-year age groups.

For around 70 cancers, the cancer survival data visualisations contain:

  • observed cancer survival rates (survival for 1 to 5 years)
  • relative cancer survival rates (survival for 1 to 5 years)
  • conditional cancer survival rates (that is, the rate of surviving an additional 5 years where a person has already survived 1 to 5 years after diagnosis)

For around 60 cancers, the state and territory data visualisations contain:

  • the number of cancer cases diagnosed between 1982 and 2017, by state and territory
  • the rate of cancer cases diagnosed between 1982 and 2017, by state and territory
  • the number of deaths from cancer between 1982 and 2017, by state and territory
  • the rate of death from cancer between 1982 and 2017, by state and territory

For around 70 cancers, cancer risk data visualisations contain:

  • the risk of being diagnosed with cancer between 1982 and 2021, by age
  • the risk of death from cancer between 1971 and 2021, by age
  • cancer risk adjusted for competing mortality and cancer risk unadjusted for competing mortality.

All interactive data visualisations contain information by sex.

Pivot tables that provide cancer incidence counts by 3 character ICD-10 codes are located in the Data section. Rates by age are now available within the raw data but do not appear in the pivot table.

CdiA core statistics part 2, cancer by stage (data updated December 2018)

The latest national data are provided on cancer survival, and incidence, by stage of cancer at diagnosis for the 5 most commonly diagnosed cancers (melanoma of the skin, and breast, prostate, lung and colorectal cancers) in 2011. The cancer incidence and survival by stage data visualisation remains available within this report; information remains unchanged from the previous release of this report because more recent cancer incidence and survival by stage data are not available.

Cancer data available as supplementary tables

Supplementary tables are available containing the data used to inform the above-mentioned statistical reports.
