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

Deaths from lung cancer, persons aged 0 to 74 years, 2016 to 2020

Policy context: Lung cancer was the leading cause of cancer death in Australia at all ages in the years 2016 to 2020 and was estimated to represent the fourth most commonly diagnosed cancer in both men and women in 2020 [1,2]. Over this period, there were 42,540 deaths from lung cancer, 24,878 males and 17,662 females at all ages [2]. While the incidence rate for lung cancer in men has been decreasing, there has been a marked increase in the incidence rate in females. Similarly, while the five-year relative survival from lung cancer has increased for both sexes, survival from this disease remains low, at 20% (17% for males and 25% for females [3]. The different pattern of incidence rates in males and females reflect historical differences in the take-up of smoking.

In Australia, tobacco smoking is the largest single cause of lung cancer, responsible for about 90% of lung cancers in males and 65% in females. The risk of lung cancer among smokers is strongly related to duration of smoking and the number of cigarettes smoked [4]. Exposure to second-hand smoke (also known as passive smoking) is also a cause of lung cancer. Other potential causes include radon gas, exposure to industrial and chemical carcinogens, air pollution, family history of lung cancer and previous lung diseases [4].

Age-standardised mortality rates for lung cancer increased from 31.1 per 100,000 population in 1968 to 42.9 per 100,000 population 1989, after which they decreased to 28.1 per 100,000 in 2019 [5]. The trends for males and females differed: the rate for males increased sharply to 1981 and then declined relatively steadily to a rate of 35.6 deaths per 100,000 males in 2019, when it was 64.1% above the female rate (which is the smallest gap); the female rate increased steadily over most of this period, although has declined in recent years, to a low of 21.7 deaths per 100,000 females [5].

For 2016 to 2020, over half (53.5%) of deaths from lung cancer were premature, with 53.1% for males and 54.0% for females – 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.
