Tumor marker cancer screening is one of the most convenient and economical diagnostic methods of cancer detection. This is done by taking a patient’s blood sample to be examined and find out the risk of developing different types of cancer.
This test determines the presence of tumor markers in tissue, blood, urine, or other bodily fluids. Most tumor markers are produced by both normal and cancer cells, but cancer cells produce more of them. A high level of a tumor marker could indicate cancer or other benign (noncancerous) conditions. It can also be used to help plan treatment, determine how well treatment is working, and determine if cancer has returned.
