Beyond the Symptom: Five Biomarkers Poised to Redefine Early Disease Detection Before 2030
Advances in genomics, proteomics, and metabolic profiling are yielding a new generation of biological signals capable of identifying serious diseases years before patients experience any clinical symptoms. From cell-free DNA circulating in the bloodstream to volatile compounds exhaled with each breath, researchers are racing to validate biomarkers that could fundamentally alter the trajectory of cancer, Alzheimer's disease, and cardiovascular illness in the United States. Here, we examine five o
