Biomarkers for disease

Biomarkers are measurable indicators in the body—such as molecules, genes, or cells—that can signal the presence or progression of a disease. They help doctors detect conditions early, monitor how well treatments are working, and understand the disease’s severity. For example, certain proteins in the blood can indicate cancer, while blood sugar levels can signal diabetes. Biomarkers are valuable tools that provide objective, scientific clues about health, enabling more accurate diagnosis and personalized treatment plans.
