Breast cancer incidence and mortality in Auckland, 1981-6.
Age standardised incidence and mortality rates were calculated for breast cancer for the Auckland area. Incidence of female breast cancer for 1981-4 was significantly higher in Auckland compared with all New Zealand, with a standardised incidence ratio of 1.11. While total incidence was the same across the three Auckland districts, there were wide discrepancies in mortality rates. Women in Takapuna had a far lower risk of dying of breast cancer compared with all New Zealand for 1981-6 and had a standardised mortality ratio of 0.86. Central Auckland and south Auckland women had increased risks--1.10 and 1.18 respectively. Similar discrepancies were evident in the important 45-64 age group. Possible reasons for the reported differences are discussed with socioeconomic factors seeming the most likely agency.
