Donna, 42, was first diagnosed with breast cancer seven years ago. Since then, she has been battling the disease as it has spread to her lymph nodes, shoulder and spine.
She struggled, both practically and emotionally, with how to explain her cancer to her youngest son Kai.
Donna was desperate to answer his heartbreaking question: “Of all the mummies in the world, why is this happening to my mummy? Why my mummy?”
Last night on The Project, Carrie Bickmore threw her support behind Donna to talk about how important it is to have her book Why My Mummy? published.
