Diagnosis rates

<Back

Around 3000 women are diagnosed with breast cancer each year - that's over 50 women diagnosed every week. The number of women each year who die from breast cancer is between 600 and 650 - that's over 12 every week.

The following table shows that while the number of people (female and male) diagnosed with breast cancer in NZ is increasing (18% over the last decade), the death rate from breast cancer in NZ decreased by 24% from 1995 to 2005.

Some possible explanations for the increasing incidence are:

  • An increase in the number of women attending breast screening
  • An aging population - simply getting older increases the risk for most cancers
  • Lifestyle factors, such as increase alcohol consumption and the rise of obesity rates
  • Having children at an older age, and having fewer children, along with a reduction in breastfeeding rates
