Researchers have developed a simple blood test that shows promise in detecting multiple cancers, various liver conditions, and organ abnormalities simultaneously by analyzing DNA fragments in the bloodstream.
The study, published in the Proceedings of the National Academy of Sciences, describes a method called MethylScan. This approach analyzes cell-free DNA (cfDNA), which are small fragments of genetic material released into the blood when cells die. Because cells from every organ shed DNA into the bloodstream, cfDNA carries molecular signals that reflect health status throughout the body.
