My name is Gabin. I was diagnosed with B-cell lymphoblastic leukemia in July 2025, when I was 18 months old. I spent a lot of time in hospital, undergoing many rounds of chemotherapy over nine months, before moving on to maintenance treatment. This is a less intensive phase, with chemotherapy at home and hospital visits once a month. That was when I was finally able to go back to daycare and play with my friends again.

But on September 2, a routine blood test brought devastating news for my parents and me: my leukemia had come back. We didn’t go back home, and I immediately started new rounds of chemotherapy, stronger than before. The doctors told us that I would need a stem cell transplant to recover—that it was my only chance.

Blood samples were then taken and could be entered into the registry: a search could begin for the closest possible donor match, giving me the best chance of recovery. For now, I am still waiting for a donor, and I hope my genetic twin is out there on one of the donor registries
