The family of young cancer fighter Stacey Mowle are another step closer to holding talks with US medical experts after crucial tests revealed her condition has improved.

The eight-year-old underwent three days of hospital checks to determine if her latest round of chemotherapy had managed to control the disease in her bone marrow.

Stacey, of Trafalgar Road, Gravesend, suffers from relapsed neuroblastoma for which there is neither treatment in the UK nor NHS funding.

She was first diagnosed with neuroblastoma, which attacks the nervous system, in 2010 but was given the all-clear the following year after vigorous treatment.

However, in 2012 came the devastating news that the cancer had returned. Since then her family and an army of supporters have been campaigning to raise the £500,000 needed to pay for her specialist treatment in the US.

Stacey is under the care of the Royal Marsden in Surrey and last week her family were delighted to be told that although the bone marrow was still present, there had been improvement.

Two further intense chemotherapy cycles, each lasting eight hours a day for five days, are already under way but Stacey’s dad Warren described the news as “brilliant”.

The 41-year-old added: “After these cycles Stacey will have a recovery period and then scans or tests will reveal if there is further improvement.

“At this stage we will meet with the UK professor treating Stacey and a US specialist to determine the next course of action.

“It is brilliant, positive news and had there been no improvement it would have been extremely serious.

“Although Stacey is still too ill to be referred to the US, if improvement continues then the US is a real possibility.”

As well as raising the necessary money, Stacey Mowle Appeal supporters are urging people to share her story as a way of grabbing worldwide media attention.

They said the plight of Ashya King, the young boy suffering from a brain tumour whose parents took him from hospital sparking an international police hunt which led to treatment being provided, demonstrated how “shouting or acting loudly enough” can make a difference.

They are now encouraging people to continue sharing their appeal video on YouTube, attend fundraising events, and to support all their social media appeals.

A spokesman for The Stacey Mowle Appeal posted on Facebook that while it was “unlikely” that Ashya’s treatment would be available to Stacey, it was “not a coincidence” that funding became available once his story gained worldwide press and social media attention.

Reassuring followers that her family would not be resorting to such drastic action, a spokesman said: “We are not about to do the same, but it does demonstrate if you shout or act loud enough you will get people’s attention, people who can make a difference.

“This is why we ask you all to share the appeal video, share the appeal press releases, share and attend the appeal events. This is why we ask you take selfies – to go viral.”

The post continued: “Don’t look at other children and ask ‘why not Stacey?’, ask yourself what we can do, what you can do, what you have done.

“We are the best appeal supporters ever, everyone knows that, everyone understands that, a loud bunch of truly inspirational people – we can really make a difference, so let’s do it and do it now.”
