Laboratory Tests
Although no single test can be used to diagnose cancer, laboratory tests such as blood and urine tests give the doctor important information. If cancer is present, lab work may show the effects of the disease on the body. In some cases, special tests are used to measure the amount of certain substances in the blood, urine, other body fluids, or tumor tissue. The levels of these substances may become abnormal when certain kinds of cancer are present.
