Less than two weeks ago, Dakota Rose was a normal nine-year-old girl, loving family, netball and riding motorbikes.

The next day she felt a pain in her side. Within days the hard lump was discovered to be a type of cancer mostly restricted to women five times her age, an ovarian tumour.

By Friday, doctors in Brisbane had operated to remove as much of a 13-centimetre tumour that had spread throughout her abdomen as they could.

On Wednesday, she was enduring her second blast of chemotherapy with grandma Gracie Cooper by her side as doctors at the Lady Cilento Children's Hospital tried to destroy the rest of the cancerous cells.
