Cancer Biomarkers: Transforming Early Detection and Personalized Treatment
Cancer biomarkers have emerged as a powerful tool in modern medicine, helping doctors understand, detect, and monitor cancer with greater accuracy than ever before. These biomarkers are measurable substances—such as proteins, genes, or molecular changes—that can signal the presence or progression of cancer inside the body. As science advances, biomarkers are becoming essential in shaping personalized treatment strategies and improving patient outcomes.
At the core, cancer develops when cells grow uncontrollably due to genetic or molecular alterations. Cancer biomarkers serve as biological footprints of these changes. Some biomarkers appear in the bloodstream, urine, or tissues, while others are embedded deep within the DNA or RNA of cells. Their presence can reveal critical information: whether a tumor is forming, how aggressive it might be, or how well the body is responding to therapy.
One of the most valuable benefits of biomarkers is early…
