Dallas, TX – Dak Lopez, a brave little boy fighting Leukemia, needs a blood stem cell transplant. His family has partnered with DKMS, an international non-profit dedicated to the fight against blood cancer and other blood disorders, to find a matching donor.

Dak Lopez was first diagnosed with Leukemia in April 2022. After undergoing chemotherapy, he is currently in remission, but his cancer is aggressive, and doctors say Dak will need a blood stem cell transplant to prevent it from returning. "You know, doctors have said that this is his only possible way of being cured," Dak’s father, Adam Lopez, said.

Dak is a happy little boy who enjoys fishing and playing outside with his friends and family. He has grown up surrounded by sports, his father is a multi-sport coach at their local middle and high schools and Dak was named after Dallas Cowboys quarterback, Dak Prescott, who sent him some words of encouragement “I just wanted to say, I love your name. Stay strong my man, you’ve got me in your corner, the Cowboys are in your corner, blessings to you, and see you next season.”

Dak’s search for a donor is made more complicated by his Hispanic heritage. According to DKMS, 70% of patients in need of a donor must find one outside of their family. Patients are more likely to find an unrelated donor of a similar ethnic background, but the current pool of available donors is not as diverse as it needs to be for every patient to have an equal chance of finding a donor. Patients of Hispanic heritage, like Dak, have just a 46% of finding a matching unrelated donor.

Dak’s family hopes that his story will encourage more people, especially members of the Hispanic community, to sign up as potential donors, "We want this to be able to help not only Dak, but other kids, other people that are in need of a donor," Dak’s father said. Anyone in good health between ages 18-55 is encouraged to request a free swab kit at to see if they are a match for Dak or another patient in need.
