Welcome to our comprehensive guide on Precision Oncology. In this article, we delve into Understanding Biomarker Testing in Cancer, exploring the latest advancements and essential information.
A biomarker is a biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process. In cancer, biomarkers are often specific genetic mutations or proteins produced by the tumor.
It is performed to understand the unique characteristics of a patient's tumor. This information helps oncologists determine the cancer's prognosis and select the targeted therapies that are most likely to work.
It is increasingly becoming the standard of care, especially for advanced cancers like lung, breast, and colorectal cancer, where several biomarker-driven treatments are already available.
