 A mystery donor has given £100,000 to an ill four-year-old boy to enable him to go to the US for potentially life-saving cancer treatment. 
  
 The parents of Zac Oliver from Broseley, Shropshire, who has a rare strain of leukaemia, have been campaigning to raise £500,000. 
  
 The donation, first reported in the Daily Mail, ensured the family reached its target. 
  
 NHS England has been asked to comment on why Zac cannot be treated in the UK. 
  
 Zac's mother Hannah Oliver-Willetts, 33, who is an occupational therapist, said she received a phone call out of the blue telling her "not to worry" and "pack her bags", reassuring her it was not a hoax. 
  
 Hours later, the money appeared in their bank account. 
  
 "It takes a very special type of person to do that", she said.

 He is believed to be the only child in the UK with the near-haploid strain of the disease, a condition that affects only one in 200 childhood leukaemia patients worldwide. 
  
 He is not eligible to receive the type of treatment he needs in the UK because his condition does not currently meet criteria set by the NHS, his parents said. 
  
 Doctors at the Children's Hospital of Philadelphia say its 17-week CAR T-cell therapy will give Zac a 60 to 80 per cent chance of survival, she added. 
  
 Speaking on the BBC's Victoria Derbyshire show on Wednesday, Mrs Oliver-Willetts said: "Hopefully we will come back with a cured little boy who will get his life back." 
  
 His parents managed to raise £400,000 in just a few weeks thanks to the donations of neighbours and friends in Shropshire. 
  
 They ran a special event called ZacFest in Telford Town Park last weekend that is understood to have raised about £10,000.

 X-Factor judge Simon Cowell also pledged to donate £50,000 to the appeal. 
  
 Zac will now undergo chemotherapy at the Princess Royal Hospital in Telford and will travel to the US after a week of recuperation at home. 
  
 "Everyone who saw a donation pot and threw a quid in, every child who emptied their money box... we can't thank everybody enough", Mrs Oliver-Willets added. ||||| The donation came after Zac's father Mark had estimated the total to be £420,000. 
  
 It is the culmination of a huge fundraising campaign that first captured the hearts of Zac's hometown Broseley, then Shropshire, and now the country. 
  
 The total means Zac's parents, Hannah and Mark, can now begin the preparations for taking him to Philadelphia where he can undergo CAR-T therapy unavailable on the NHS.

 "Today we received a very large anonymous donation. This means that as soon as all of the money which people have raised and told us about has been banked, we will be able to show The hospital of Philadelphia and get financial clearance. As soon as we get financial clearance, we can send this to the Embassy and get Zacs visa confirmed. There is around £116,000 outstanding. We urge you all to please please please count and bank what you have.

 "We are absolutely amazed at all of your dedication, commitment and hardwork to have got us to this position in such a short amount of time. In fact we honestly can't express just how happy and excited we are right now to be able to say that we WILL be able to get Zac the treatment he needs to have the best chance of survival. 
  
 "Unfortunately we are not quite out of the woods yet. We still have a very hard and tiresome road ahead of us over the next 4 months. But with any luck we will be able to celebrate in about 4 months time after Zac has had his car-t therapy, that you all made possible. Please can you all raise a glass tonight as tonight marks the days when we can all smile and breath for a moment in piece and happiness.

 "Now we have reached £500,000 (including everything that's not quite banked yet). We can safely say that Zac can have his treatment and we can afford part of our accommodation and food. We do however, need to return to the US every 3 months for a year and every 6 months for 2 years for bone marrow biopsies. We haven't worked out how we will pay for this. 
  
 "So we would like to ask you all if you could please to continue to fund raise to ensure we can successfully finish Zacs treatment. We also found out today that Zacs night feed and out patient medication will cost over £1000 a month whilst we are out there. So if we can just keep going until Christmas at least we will know that we are on safe ground. 
  
 And as for the mystery donor. Well, I can tell you all, that is such an interesting story, but I've waffled on far too long so will have to tell you all about it at another time. 
  
 Much love and hugs xxxx"

 In the video he said: "I want to talk to you about Zac and Zacfest. This boy is four years old and needs money to get him to America to get the help he needs. So I want you please to go on Zac Oliver's JustGiving page and whatever you can donate will make a difference. And because I don't like well-known people telling people to do something and don't do anything themselves, I'm going to donate £50,000. We're going to get there." 
  
 Hannah Oliver-Willets, Zac's mother, shared the video on social media, adding: "Thank you to Simon Cowell for doing such an amazing job at supporting our cause. I explained to Zac that Simon has helped to pay for his special medicine. Zac said 'thanks si' lol, little does he know exactly what this actually means and how much closer we really are to getting him to the US." 
  
 In a later post Hannah added that there was only £100,000 left to raise to reach Zac's £500,000 target.

Output:
A 4-year-old UK boy is $130,000 closer to traveling to the US for cancer treatment after a mystery donor contributed that amount to the cause. Zac Oliver was diagnosed with acute lymphoblastic leukaemia in May, but he has the near-haploid strain of the disease, which affects just one in 200 childhood leukemia patients. He is thought to be the only child in the UK with that strain of the illness, the BBC reports. Friends and family have been working on raising the more than $650,000 needed to get Zac to Philadelphia for a promising new treatment the UK is not yet ready to deliver, according to a JustGiving crowdfunding campaign for the little boy. Zac's mom, Hannah Oliver-Willetts, says she was recently shocked with a phone call from someone who told her "not to worry" and to "pack her bags." Hours after the call, the massive donation appeared in the family's bank account, she says; the amount reportedly pushed the total to what the family needs to afford the CAR-T therapy and all associated costs. The 4-year-old's plight had already been getting big attention, with Simon Cowell pledging about $65,000 to the cause. With the goal reached, "This means that as soon as all of the money which people have raised and told us about has been banked, we will be able to show The hospital of Philadelphia and get financial clearance," Zac's mom posted on Facebook, per the Shropshire Star. "As soon as we get financial clearance, we can send this to the Embassy and get Zacs visa confirmed. ... We honestly can't express just how happy and excited we are right now to be able to say that we WILL be able to get Zac the treatment he needs to have the best chance of survival."
