Blood cancers that eventually worsen may carry detectable genetic warning signs years before patients develop serious symptoms. The findings could lead to earlier intervention while also helping doctors distinguish true cancer from harmless age-related blood changes.
Genetic “family trees” of blood cells may reveal years in advance which cancers will progress and which patients may not have cancer at all.
Long-term tracking of chronic blood cancers has revealed major genetic differences between patients whose conditions remain stable and those whose diseases eventually become more severe. The findings suggest that DNA changes may help doctors improve diagnoses, monitor patients more accurately, assess how treatments are working, and identify signs of progression years before symptoms become obvious.
Published in Cancer Discovery, the study was led by researchers at the Wellcome Sanger Institute and their collaborators. The team combined genetic analysis with detailed clinical records to investigate how chronic blood cancers can develop over several decades. The findings were also presented at the American Association of Cancer Research (AACR) Conference in San Diego.
