Benign growth, or cancer? Tumor markers in the blood help determine whether the patient is afflicted with a malign tumor and whether it is excreting markers more vigorously – involving highly specific proteins. An increased concentration in the blood provides one indication of the disease for physicians. However, it has been quite expensive in time and effort to detect the markers thus far. This is because all kinds of molecules and proteins are teeming in the blood. To be able to detect a single specific one, doctors must first separate and purify the blood in several steps, and then isolate the marker they are searching for from the rest of the molecules.
