How Are Biomarkers Used in Cancer Diagnosis and Treatment?
Biomarkers are molecular signatures found in blood, other body fluids, or tissues that indicate a normal or abnormal process, or a condition or disease, such as cancer. They play a crucial role in cancer diagnosis, prognosis, and treatment selection. For instance, the presence of the PD-L1 protein on tumors can predict response to certain immunotherapies. Biomarker testing helps in identifying suitable candidates for specific therapies, enhancing treatment efficacy and minimizing unnecessary treatments.
