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

Deaths from breast cancer, females aged 0 to 74 years, 2010 to 2014

 

Policy context:  In 2007 in Australia, breast cancer was the second most common cause of cancer death among Australian females, exceeded only by lung cancer [1]. In the five years from 2003 to 2007:

  • the age-standardised mortality rate varied by remoteness;
  • there was no consistent association between the mortality rate and socioeconomic status;
  • mortality did not differ between Aboriginal and Torres Strait Islander females and non-Indigenous females [1].

In 2007, 13% of deaths from breast cancer in females occurred in those younger than 50, 40% in those aged 50-69 and 47% in those aged 70 years and over [1].

The proportion of cancer deaths of females that were due to breast cancer fell from 19% in 1982 to 16% in 2007. This decline is believed to be due mainly to increased availability and quality of screening mammography (and the related increase in diagnoses at an earlier stage), as well as improved treatment [2] [3] [4].

For deaths data released since 2007, the 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 each release, the latest year’s data is preliminary, the second latest is revised and the data for the remaining years is final.
