Cancer Biomarkers

Description:

A cancer biomarker is a substance or activity that can be used to detect the presence of cancer in the body. A biomarker is a chemical produced by a tumour or a specific body reaction to the presence of cancer. A biological molecule found in blood, other bodily fluids, or tissues that indicates if a process is normal or aberrant, or whether a condition or disease exists. A biomarker can be used to determine how well the body responds to an illness or condition's therapy. Also known as a signature molecule or a molecular marker. Biomarkers for cancer can also be used to narrow down a diagnosis. This tumour marker can be seen in the blood, saliva, or urine of patients.
