What is the Importance of Biomarkers in Cancer Diagnosis?
Biomarkers are biological molecules that indicate the presence of cancer in the body. They can be detected in blood, urine, or tissues and are essential for early diagnosis, prognosis, and monitoring treatment responses. Biomarkers like CA-125 for ovarian cancer or PSA for prostate cancer have revolutionized the diagnostic process, enabling more accurate and non-invasive testing.
