“I never planned to go into research, but everything changed when I lost my mum to mesothelioma.” Mackenzie Lighton, researcher at the Institute.
Mackenzie’s mum, Debra, was brave, funny and full of love. She could find beauty and joy in almost anything and had a cracking sense of humour. Even when she was in pain, she still tried to make people laugh.
She did not live in fear. She encouraged Mackenzie and her sister to live boldly and to go after what mattered to them.
What Mackenzie misses most is her mum’s love. Her smile. Her warmth. The way she backed Mackenzie in whatever path she chose.
When Debra was diagnosed with mesothelioma, Mackenzie wanted more time with her. More treatment options. More hope.
After Debra passed away, Mackenzie could not shake the feeling that she needed to do something.
Research gave her a way to turn grief into something meaningful.
Today, Mackenzie works alongside Dr Alistair Cook at the Institute on mesothelioma research that could help change what families face after a diagnosis.
For Mackenzie, this work is a way to honour her mum and help other families facing mesothelioma.
If you would like to support this research, please donate before 30 June. Your gift will be doubled and help give back more time to families facing mesothelioma.
