For Australian women, the risk of being diagnosed with breast cancer before the age of 85 is one in eight.6
Although the incidence of breast cancer for women has increased over the past 20 years, the risk of dying from breast cancer has decreased. Between 1994 and 2014, the age-standardised mortality rate for breast cancer in women decreased by 30 per cent (from 30.9 deaths per 100,000 women in 1994 to 19.6 deaths per 100,000 women in 2014).68
Improvements in early detection and treatments have significantly contributed to lower mortality rates.11 The five-year relative survival rate for Australian women with breast cancer during 2009-2013 was 90.2% 68, compared with 73% in 1982-87.4
Consequently, the number of people living with a breast cancer diagnosis has increased. At the end of 2012, there were 15,092 people living who had been diagnosed with breast cancer that year, 65,976 people who had been diagnosed with breast cancer in the previous 5 years (from 2008 to 2012) and 193,730 people who had been diagnosed with breast cancer in the previous 31 years (from 1982 to 2012). 69
Age-standardised incidence of female breast cancer is significantly higher in major cities than in other areas. During 2004-2008, 114 new cases of breast cancer were diagnosed per 100,000 women in major cities. Comparatively, incidence rates were lower in remote and very remote areas (94 per 100,000 women).4 This is related to a significantly higher incidence of breast cancer in high socioeconomic status areas.4 A contributing factor may be the lower rates of mammographic screening in very remote regions.4
