Jaimey was diagnosed with prostate cancer in 2008. He was treated and received a clean bill of health and remained cancer-free. In May 2015, a routine blood donation led to a life-changing discovery when the Red Cross director urged him to seek immediate medical attention. Jaimey was diagnosed with chronic lymphocytic leukemia (CLL), which, contrary to its typical slow progression, advanced rapidly in his case.

Jaimey remained active, cycling and running to maintain his mental well-being.
However, six to nine months ago, his CLL numbers began to rise again, prompting
discussions about future treatments. Although his white blood cell count is high and he has low antibodies, making illnesses particularly severe, Jaimey remains optimistic with Dana-Farber's support.

After obtaining an A.B. cum laude in chemistry at Harvard College, Dr. Davids
completed his M.D. cum laude at Yale University School of Medicine. He served as an intern, resident, and assistant chief resident in internal medicine at New
York-Presbyterian Weill Cornell Medical Center and Memorial Sloan-Kettering Cancer Center in New York City. He then completed his fellowship in hematology and oncology in Dana-Farber/Partners CancerCare, and a Masters in Medical Science (M.M.S.c.) at Harvard Medical School. He is an attending physician in the Division of Lymphoma, and serves as the Director of Clinical Research, as well as Associate Director of the CLL Center. He is also an Associate Professor of Medicine at Harvard Medical School, and attends on the inpatient hematologic malignancies service at Brigham and Women's Hospital.

Acute lymphocytic leukemia is the most common type of cancer in children, and
treatments result in a good chance for a cure. Acute lymphocytic leukemia can also occur in adults, though the chance of a cure is greatly reduced.
