Notes

  1. ASR is age-standardised rate, standardised to the Australian 2001 population.
  2. APC is the average Annual Percent Change in ASR calculated from a log linear model, fitted to rates over the years 2001 to 2010. For further information refer to Appendix 4 of the Cancer in NSW: Incidence and Mortality Report 2010.
  3. At the time this report was produced, 2009 death data had not been processed and 2009 incidence excludes death certificate only (DCO) cases. For further information please refer to Appendix 3 of Cancer in NSW: Incidence and Mortality Report 2010.
