Researchers have created a liquid biopsy controlled by artificial intelligence that scans for patterns in DNA fragments circulating in the blood. The system detects early liver fibrosis and cirrhosis years before symptoms appear. These conditions often go unnoticed until severe liver damage occurs. The approach analyzes genome-wide patterns of DNA fragmentation instead of specific mutations. It thereby captures hidden signals about a person's overall health. Early detection allows doctors to treat liver disease earlier. This could help prevent liver cancer.
