What tests are used to evaluate liver cancer?
Blood tests: Some tumors produce measurable amounts of chemicals known as tumor markers in the blood. Blood tests for the presence of these markers can be used to help diagnose or monitor the disease process. Other tests measure the functions of the liver and other organs. Ultrasound (US): This test uses sound waves to form a picture that can be seen on a small television screen. The picture can show organs in the abdomen and possibly the presence of a tumor. Ultrasound is commonly performed by placing a probe on the surface of the abdomen. Computed tomography (CT) scan: By means of a special type of X-ray machine, this test gives detailed pictures of the body and can show how far the cancer has spread. The CT scan is the primary test used to determine the number and size of tumors in the liver and whether the tumor can be surgically removed. Magnetic resonance imaging (MRI): By means of a magnetic field, precise images of the liver can be obtained. This test is ordered when further de
