There were tears at Dunedin's St Hilda's Collegiate School yesterday as principal Melissa Bell unexpectedly announced she would resign at the end of this year.
The 41-year-old was diagnosed with an aggressive form of breast cancer last March, but she went to great lengths to reassure staff and pupils during a special assembly yesterday that her decision to resign was not connected to her health.
After surgery, 12 rounds of chemotherapy and five weeks of radiation treatment, Ms Bell returned to full-time work last October, and her doctors had since given her a clean bill of health.
During her treatment, she turned the adversity into an inspirational life lesson for her pupils by sharing details of her illness, treatment and emotions, in a bid to give her pupils the tools to deal with breast cancer if they experienced it in later life.
''I guess the experience has probably taught me that you can't assume anything about what the future holds, and you've got to do what you really want to do, when you want to do it,'' she said.
