Mum Julia said: "She was diagnosed at the beginning of the summer holidays after she started showing signs of early puberty. The first thing I noticed were her mood swings, she turned into a teenager overnight. The tumour they found was the size of an orange. I was told when it's in your stomach, your bowels move around so it can be masked. But she was lucky it protruded, it looked like a pot belly and the GP was soon on the ball."
All through her treatment, Niamh, was brave and positive but she missed gymnastics.
"She's not been fazed by the cancer at all. She's such a bubbly girl - always laughing and smiling. She's a little soldier, " Niamh's mother said.
