A Merseyside mother is urgently appealing for a life-saving bone marrow donor for her eight-month-old son, Leo, who is battling a rare and aggressive form of blood cancer. Laura McAllister, from Eastham, Wirral, launched the desperate plea after Leo was diagnosed with acute myeloid leukemia (AML) in late January. The search for a matching donor is critical, as Leo’s mixed heritage – his father is Jamaican – makes finding a suitable match significantly more challenging.
The diagnosis came after weeks of Leo being unwell, initially dismissed as a cold. However, his condition rapidly deteriorated, leading to a hospital visit and subsequent blood tests that revealed the devastating news. “It was just a normal day, and then our world was turned upside down,” McAllister told the BBC. “To be told your baby has cancer, it’s just… unimaginable. And to know that his best chance of survival relies on finding a stranger willing to donate, it’s incredibly daunting.”
Acute myeloid leukemia is a type of cancer that affects the blood and bone marrow. It’s characterized by the rapid growth of abnormal white blood cells, hindering the body’s ability to fight off infection. In infants, AML is exceptionally rare, accounting for less than 1% of all leukemia cases, according to the American Cancer Society. Treatment typically involves intensive chemotherapy, but a bone marrow transplant – too known as a stem cell transplant – offers the best chance of long-term survival, particularly in cases like Leo’s where the leukemia is aggressive.
The Challenge of Finding a Match
The difficulty in finding a suitable bone marrow donor for Leo stems from the importance of Human Leukocyte Antigen (HLA) matching. HLA markers are proteins found on white blood cells that aid the immune system distinguish between the body’s own cells and foreign invaders. A close HLA match is crucial to prevent the recipient’s immune system from rejecting the donated cells.
Ethnicity plays a significant role in HLA matching. People from the same ethnic background are more likely to share similar HLA markers. Because of Leo’s mixed heritage, the pool of potential donors is considerably smaller. The DKMS, a leading international blood cancer charity, highlights that people of Black, Asian, or mixed-race backgrounds are significantly underrepresented on donor registries. This disparity means that patients from these communities often face longer waits and a lower chance of finding a life-saving match.
“We’re urging people of all backgrounds to register as potential donors,” says a spokesperson for DKMS UK. “But we particularly require more people from minority ethnic groups to come forward. You could be the one to give someone like Leo a second chance at life.”
How Bone Marrow Donation Works
The process of becoming a bone marrow donor is simpler than many people realize. Potential donors register online with a bone marrow registry, such as DKMS, Anthony Nolan (in the UK), or Be The Match (in the US). Registration typically involves completing a health questionnaire and providing a cheek swab sample to determine HLA type.
If a donor is identified as a potential match, they will undergo further testing to confirm compatibility. If confirmed, the donation process itself is usually carried out in one of two ways: Peripheral Blood Stem Cell (PBSC) collection or bone marrow harvest. PBSC collection is the more common method and involves collecting stem cells from the donor’s bloodstream after they have been stimulated to produce more stem cells with medication. Bone marrow harvest involves extracting liquid bone marrow from the hip bones under anesthesia.
Leo’s Treatment and the Urgent Appeal
Leo is currently undergoing chemotherapy at Alder Hey Children’s Hospital in Liverpool. While the chemotherapy is aimed at reducing the number of cancerous cells, it is not a cure. A bone marrow transplant is considered his best hope for a lasting remission.
The family has launched a social media campaign, #LeoNeedsAHero, to raise awareness of Leo’s situation and encourage people to register as potential donors. The campaign has gained significant traction, with thousands of people sharing Leo’s story and urging their friends and family to sign up.

The family is also working closely with DKMS and Anthony Nolan to organize donor registration events in the Merseyside area. These events aim to increase the number of potential donors, particularly from underrepresented ethnic groups.

The next critical step is to increase the number of potential donors on the registry and find a match for Leo as quickly as possible. The family remains hopeful, but time is of the essence. The search continues, fueled by the unwavering love of a mother and the hope that a stranger will answer Leo’s call for a life-saving gift.
