Understanding Cancer Biomarkers: The Key to Early Detection and Personalized Therapy
Cancer continues to be one of the leading causes of death worldwide, making early detection and effective treatment critical. One of the most promising advances in oncology is the use of cancer biomarkers. These biological molecules, found in blood, tissues, or other bodily fluids, can signal the presence of cancer, guide treatment decisions, and monitor disease progression.
What Are Cancer Biomarkers?
A cancer biomarker is a substance or process that indicates the presence of cancer in the body. These markers can be genes, proteins, or other molecules that are either produced by cancer cells themselves or by the body in response to cancer. Biomarkers play a crucial role in oncology because they provide information that cannot be obtained through traditional imaging or physical examinations alone.
