Blood test detects cancer early

A new blood test can detect cancer signs years before symptoms appear, potentially improving treatment outcomes. Researchers found that genetic material from tumors can be detected in blood samples up to three years before a cancer diagnosis, using advanced genome sequencing techniques. The study analyzed blood samples from participants, identifying cancer-related mutations in some individuals before they showed any symptoms. This breakthrough could lead to more frequent blood screenings, enabling earlier cancer detection and potentially preventing the development of treatment-resistant tumors. Further research is planned to validate these findings in a larger study.
