One Australian child dies of cancer every week, and Caitlyn could have been one of them if it wasn't for cancer research.
Not many people count Friday 13th as their luckiest day, but then the Gwyther family - David, Kaye and daughters Caitlyn and Taylor - aren't most people.
The results of 10 year old Caity's tonsillectomy that day turned out to be anything but routine - she has B cell non-Hodgkin lymphoma.
An epic treatment regimen followed. Caity underwent five rounds of chemotherapy, her protocol honed by medical research - clinical trials into the therapy of non-Hodgkin lymphoma in children - which meant that her treatment, while months-long and intense, was less gruelling, with fewer potential side effects than children previously endured.
Caity has been clear of lymphoma for more than five years.
She's about to embark on Year 12 at school and has every reason to expect a normal, healthy, long life.
And why is Friday 13th lucky? It's Taylor's birthday, and that tonsillectomy probably saved Caity's life by giving her a diagnosis and effective treatment. David says it's made the family "much more aware of what medical research can achieve - we're so grateful".
What we're doing.
Australia has one of the highest incidents of childhood cancer worldwide - the diseases take at least one Australian child's life every week. So treating childhood cancers is an urgent priority.
Children's Medical Research Institute's Dr Megan Chircop undertakes research that moves discoveries and treatments from benchtop to bedside, where they can be of most use treating children and saving lives.
Dr Chircop's unit at CMRI studies cell division and they now understand that blocking a protein called dynamin can block cell division, which allows for cancers to spread. As a result, they are studying how dynamin inhibitors could work as anti-cancer treatments.
How you can help.
This research is at an early stage and is not government funded. We need $85,000 to allow this exciting work to continue. Without that money, Dr Chircop and her team may have to stop testing the drugs which show so much promise fighting previously untreatable brain cancers.
Please give generously so we can help more families beat this disease.
