A fit father of three whose heartburn turned out to be leukaemia has been given a “second chance” at life after just one match was found for a life-saving transplant. Neil Morris, a 44-year-old HR director from Abingdon, Oxfordshire, was diagnosed with acute lymphoblastic leukaemia (ALL), a type of blood cancer, in November 2023 after experiencing what he thought was indigestion and heartburn.
His wife Jenny Morris, a 39-year-old solicitor, said the diagnosis came as a huge shock and “turned their life upside down” as Neil, known as Moz, was “super fit and healthy” and had cycled 100km on his bike that same week. Moz had more than 100 rounds of chemotherapy, eight hours of radiotherapy, five bone marrow biopsies, five bags of platelets, three blood transfusions and more, but ultimately, it was a stem cell transplant through Anthony Nolan that saved his life.
Now, nine months post-transplant, Jenny is preparing to run the TCS London Marathon in April to raise funds for Anthony Nolan and encourage others to register as donors. Speaking about her message to the unknown donor in Germany, who cannot be identified, Jenny told PA Real Life: “There are no words to express how grateful I am.

“I suppose the only thing I can do is thank her for giving our children their dad back, for giving him a chance and for giving me my husband back. He has a second chance and the reason why he has that chance is because of her – and it’s mind-blowing there are not more people on the register.”
Jenny explained that Moz has always been fit and healthy – he enjoys cycling and running and has completed several marathons. During the week of his diagnosis in November 2023, Moz had cycled 100km and experienced tightness in his neck and chest, but he “didn’t think anything of it”, believing it was indigestion.
As the “sharp pain” persisted, however, he decided to visit his GP. “He thought it was heartburn, but I don’t think he’s ever suffered from that before,” Jenny said.“His concern was, ‘I’ve got chest pain, I ought to get checked out’.”
After a GP consultation, Jenny said Moz was advised to visit his local hospital, where a CT scan revealed a “gigantic mass on his chest”, along with a blood clot. After further tests, scans, blood tests and a bone marrow biopsy, doctors confirmed Moz had ALL on November 29 2023.
Jenny said: “Looking back, I was probably a rabbit in headlights. “My first thought was just, ‘I’ve got three children and a husband who I love’.I was shocked and, if I’m completely honest, I still don’t believe it’s happened to us, but at the same time I’ve always believed it would be OK, I just believe in him.”
Jenny said Moz started treatment straightaway, beginning with steroids, followed by three cycles of chemotherapy over six months. Even during treatment, Moz, who is “headstrong and determined”, continued to stay fit using his exercise bike to the amazement of the “incredible” staff at Churchill Hospital in Oxford.

Moz had reached remission after the first chemotherapy cycle but needed to continue with two more before having a stem cell transplant, as this was “the route to cure”. Jenny said waiting for a match to be found gave her many “sleepless nights” – and in the end, it was an unknown donor in Germany who saved his life.
“He doesn’t have siblings, so there was not the option for him to have a sibling donor,” Jenny explained. “He only had one match, which is bonkers, and we still can’t believe it.We’re very lucky that he had one and the one that he had was a good one.”
After his whole body was treated with radiotherapy, specifically total body irradiation (TBI), which caused him to lose his hair and drop 10kg in one week, Moz received the stem cell transplant in May 2024. One of Anthony Nolan’s volunteers flew to Germany to collect the stem cells and, despite various plane cancellations and delays, Jenny said “they managed to get them to him safe and sound”.
Jenny said there were some “scary moments” and he experienced some complications post-transplant, but Moz was eventually discharged to continue his recovery at home, where he had to remain in isolation for around three months due to being severely vulnerable to infection. Although Moz still has “a long way to go”, Jenny said he is now “doing incredibly well” and has been supported by medical staff, family and friends, and she has since signed up for the TCS London Marathon to “give something back”.

“If Moz can go through everything that he has gone through, then I’m pretty sure I can get myself around London,” she said. Jenny said there will be “lots of tears” when she crosses the finish line on April 27, but her mission to raise awareness is driving her forward and she has learned not to “sweat the small stuff”.
With Anthony Nolan saying only 3% of people in the UK are registered as stem cell donors currently, Jenny hopes she can encourage at least one more person to sign up. She said: “Just get on the register, it’s easier than a Covid test – you just need to fill out an online form to request a swab pack.
“I hope so much that I get called to give some cells one day, I would love to have the privilege to do that. It’s so easy and so simple and, obviously the drugs and treatment have a huge impact, but actually, what really saves the life is another person.What an incredible gift to give someone.”
