Supporters of Stacey Mowle are stepping up the pace in their campaign to raise awareness of the youngster’s cancer plight by marching on Downing Street.

A walk from her home in Trafalgar Road, Gravesend, to Trafalgar Square in the heart of London, has been triggered after organisers of The Stacey Mowle Appeal collected 10,000 online signatures.

The landmark figure means the e-petition should now elicit a written response from the government.

Stacey, seven, suffers from relapsed neuroblastoma, for which there is neither no treatment in the UK nor funding by the NHS.

For any chance of her survival her parents, Warren, 40, and Samantha, 32, have set out to raise £500,000 needed to pay for treatment in the US.

The response has been overwhelming but campaigner Steve Nash, from Vigo, said Petition4Stace was just as important to highlight the plight of other youngsters suffering from the disease.

“It is simply aimed at raising awareness and hopefully acknowledgement of Stacey, as well as neuroblastoma in general and the 100 children that are affected each year,” explained the 40-year-old.

The Mowle family and supporters, dressed in the purple appeal T-shirts, will walk the 24-mile route from Gravesend on Saturday, November 16, through Northfleet, Greenhithe, Dartford and Crayford, before converging on Trafalgar Square.

From there, they will head along Whitehall to Downing Street and hand over both a copy of the e-petition plus any paper petitions that have also been collected.

Supporters are invited to join the march at any stage.

The success of the online appeal is just one of many events that have been held in support of Stacey since her parents started fund-raising in February.

Stacey was first diagnosed with an aggressive form of neuroblastoma in May 2010 and doctors said she had an 80% chance of relapse.

After undergoing almost two years of treatment, including chemotherapy, radiotherapy and surgery, scans in December 2011 showed she was clear.

However, Stacey began to feel ill shortly after her birthday in November last year and confirmation she had relapsed came just five days before Christmas.

The appeal, which boasts celebrity patrons comedian Joe Pasquale, TV doctor Pixie McKenna and former Bucks Fizz singer Cheryl Baker, has already raised more than £120,000. Stacey has also had visits from the Duchess of Cambridge and X Factor contestant Tamera Foster.

Steve Nash, together with friend Jason Scott, 38, set out this morning on a 100-mile walk and run from Eastbourne to Gravesend to raise money for Stacey.

The pair will cover 82 miles over the first two days, with the final 18 miles, including two laps of Bluewater, being completed on Sunday.

Steve and Jason, from Gravesend, are hoping at least 100 people, one for every mile walked, will cheer them on as they walk the two floors of the shopping centre, starting from outside John Lewis at midday.

They will then trek the final five miles to the finishing line at the Six Bells pub in Northfleet.

The latest tool in the Stacey Mowle Appeal is a simple but powerful video posted on YouTube.

The Stacey Mowle Plea footage lasts no longer than two minutes but tells Stacey’s story in photographs, set to piano music.

It starts with the seven-year-old looking a picture of health as a bridesmaid at her parents’ wedding four years ago before switching to a shocking image of how the disease has devastated her tiny body.

Other photographs show Stacey undergoing treatment at the Royal Marsden Hospital in Surrey.

The video then explains that if the money needed for treatment in the US is not raised, Stacey will die.

It finishes with a plea for financial help or support through the following links www.justgiving.com/StaceyMowleAppeal and www.thestaceymowleappeal.co.uk

Stacey’s dad, Warren, said of the video: “Please share and promote the appeal plea as far as you can - all friends, family, work colleagues, Facebook and Twitter.

“It is so important and on the biggest media platform globally. Please help us turn it viral.”
