From Air Line Pilots Association:

In September 2016, Capt. David Whitson (United) was diagnosed with acute myeloid leukemia, a condition in which white blood cells that manage the body’s immune system form abnormally. The then B-787 first officer was treated at the Texas Oncology–Baylor Charles A. Sammons Cancer Center in Dallas, Tex., where he spent an initial 30 days undergoing tests and chemotherapy.

“I had a mutation called FLT3 that put me at high risk for not reaching remission and also in a high-incidence category for relapse even if remission was achieved,” he recalled, adding, “My best shot was to have a bone marrow transplant, also called a stem cell transplant. Without it, I had a 5 percent chance of survival.”

Whitson was released from the hospital for a brief break. During this period, doctors conducted a bone marrow biopsy and discovered that the pilot’s cancer was in remission, a condition necessary to achieve before a bone marrow transplant could be conducted. Whitson and his doctors quickly found a donor.

“It was hard for me to wrap my head around the fact that a complete stranger would be willing to give me bone marrow stem cells and potentially save my life,” he acknowledged. Whitson endured additional rounds of chemotherapy and a full-body radiation scan to ensure his body was ready and on Dec. 21, 2016, received the transplant. Within several days, his new immune system was up and running.

Thirteen days after the transplant, Whitson was released from the hospital. He noted that prior to the transfusion of stem cells his blood type was B+, but today it’s O-. In addition, the DNA in his blood is different from that in his body.

Whitson encourages everyone to donate blood. “I needed more than a dozen blood and platelet transfusions during my treatments,” he said. The United pilot also urges those interested to join the national bone marrow registry at bethematch.org or www.dkms.org. “There’s a lack of diversity within the registry, and minorities are greatly needed,” he shared.

“Every day is a gift,” Whitson remarked, who credits ALPA’s Aeromedical Office for advising him and helping him jump through the necessary hoops to acquire his special issuance medical certificate and return to the cockpit. He also gave a nod to his medical benefits, noting, “I was on long-term disability for more than two years, and my medical insurance was excellent. Thank you, ALPA!”
