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

Deaths from breast cancer, females aged 0 to 74 years, 2016 to 2020

 

Policy context:  In 2020 in Australia, breast cancer was the fifth-most common cause of cancer-related death in Australia and the most commonly diagnosed cancer in females [1]. In the five years from 2016 to 2020, the mortality rate was 10% below the national rate in the least socioeconomically disadvantaged areas and 5% above in the most disadvantaged areas.

In 2016 to 2020, 10% of deaths from breast cancer in females occurred in those younger than 50, 36% in those aged 50-69 and 54% in those aged 70 years and over [2].

Age-standardised mortality rates for breast cancer of females increased from 29.5 per 100,000 female population in 1968 to 31.6 per 100,000 female population 1989; there were small variations to 1994, after which rates decreased markedly to 18.6 per 100,000 in 2020 [3].

For 2016 to 2020, over half (57.9%) of all female deaths from breast 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.
