Six months after finally giving birth to her first child, following a years-long struggle to conceive, Chrissy Walters was told her daughter would likely grow up without her.

Walters had suffered a major bleed while at home in Toowoomba - a small city two hours inland of Brisbane - and several hospital visits, doctor appointments and biopsies later, the then 39-year-old was handed an advanced cervical cancer diagnosis.

"I just said to [my husband] Neil… there has been a huge mistake," Walters recalls.

She's now spent more than a decade undergoing treatments - both debilitating and incredibly invasive - but the cancer has spread to other parts of her body. Her doctors say her diagnosis is now terminal.

"I would never wish [this] on my worst enemy," she says.
