A family has been crushed by their four-year-old girl fighting against a fast-growing cancerous brain tumour.

Little Payton Gilby was told on Christmas Eve that she must have as much of the tumour removed as soon as possible and is now set for treatment due to last all year.

Worryingly for Vanessa Gilby, 29, if the medulloblastoma comes back, Payton's chances of survival are just 10%, GrimsbyLive reports.

The devastated mum from Grimsby, Lincs also has her eight-year-old son, Tyler-Jay to worry about, as Payton will need specialist treatment more than 100 miles away in Manchester.

Vanessa said: "You could never imagine in a million years that your loved one won't survive cancer.

"She is such a beautiful, kind, happy girl who does not deserve this. It is terrifying."

Payton started feeling unwell at school throughout December before doctors at Diana Princess of Wales Hospital recommended an MRI scan which revealed the tumour.

Vanessa said: "They had to operate straight away because it was an aggressive malignant tumour.

"We didn't get a chance to have Christmas together because my mum and dad looked after Tyler, while I was with Payton.

"It is going to be hard for the rest of the treatment because I will be driving all over the country," she added.

Payton has to have a line put into a vein in her neck for easy access for the treatment she is going to receive.

Her mum said the treatment she is having can make her infertile so they will also take ovarian tissue and freeze it so she can decide later in life if she would like her own children.

Now she is back home watching TV recovering from her operation and awaiting the first treatment at Manchester in three weeks.

Vanessa whose parents are helping with child care has set up a GoFundMe page for the challenges ahead, including travelling to and from hospital for a year.

Vanessa has launched a fundraising page in the hope of supporting her daughter

The page states: "My aim with the money is for me to try and give her the most normal happy life possible while having treatment, I'd love to buy her a wig when she loses her hair and pay for my son to come and visit us as many weekends as is possible.

"Payton is losing her life as she knows it, she doesn't deserve to lose her brother too."
