Scientists identify blood proteins that could flag prostate cancer a decade early
Oxford researchers have pinpointed 12 blood proteins, including seven linked to aggressive prostate cancer, offering a potential way to detect risk more than ten years before symptoms appear.
A team from Oxford University examined blood samples from 2,555 participants, tracking them for roughly 16 years, and identified 12 proteins that differentiate men who later develop prostate cancer from those who remain cancer-free. Seven of these proteins, including ANKRD1 and the immune-cell marker GZMK, are associated with the disease's most lethal variants. Researchers say the findings could eventually enable a blood test that flags high-risk individuals more than a decade before any symptoms, potentially guiding preventive strategies.
The study, the largest of its kind, involved analysis of over 6,000 proteins and was supported in part by Cancer Research UK. While the results are promising, scientists like Prabhakar Rajan note that some associations may be coincidental and further work is needed before the markers can be used clinically. The breakthrough arrives amid calls for a national prostate-cancer screening programme in Britain, where the disease claims about 12,000 lives annually.
Why it matters
Early detection of aggressive prostate cancer could dramatically reduce deaths and guide preventive treatment.
