Blood tests detect cancer years before diagnosis

A new study reveals that blood tests can identify cancer-related genetic material up to three years before a diagnosis. This early detection could significantly improve patient outcomes. Researchers analyzed blood samples from a study and found tumor-derived mutations in some participants years before their cancer diagnosis. The study used advanced sequencing techniques to analyze samples from individuals with and without cancer. The findings suggest that early detection tests could lead to earlier interventions and more curable cases. The study highlights the potential of multicancer early detection tests and the need for further research on clinical follow-up.
