Understanding Biomarkers: The Future of Personalized Medicine
Biomarkers have become central to modern medicine, representing measurable indicators that provide insights into biological processes, diseases, or responses to treatment. They are molecules, genes, proteins, or characteristics that help clinicians and researchers detect conditions early, monitor progression, and evaluate the effectiveness of therapies. The importance of biomarkers lies in their ability to offer precise and personalized approaches to healthcare.
At the core, biomarkers function as a window into the body’s internal workings. For example, blood pressure is a simple physiological biomarker, indicating cardiovascular health. In more advanced contexts, biomarkers can be molecular, such as specific proteins expressed in cancerous cells or genetic mutations that predispose individuals to certain diseases. Their applications extend from diagnostics to prognostics and therapeutic guidance, providing a bridge between laboratory research and patient care.
One of the most significant contributions of biomarkers is in the field of cancer…
