Question: How to diagnose Adult Primary Liver Cancer ?
Answer: Tests that examine the liver and the blood are used to detect (find) and diagnose adult primary liver cancer. The following tests and procedures may be used:         -   Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken.     -   Serum tumor marker test : A procedure in which a sample of blood is examined to measure the amounts of certain substances released into the blood by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types of cancer when found in increased levels in the blood. These are called tumor markers. An increased level of alpha-fetoprotein (AFP) in the blood may be a sign of liver cancer. Other cancers and certain noncancerous conditions, including cirrhosis and hepatitis, may also increase AFP levels. Sometimes the AFP level is normal even when there is liver cancer.    -   Liver function tests : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by the liver. A higher than normal amount of a substance can be a sign of liver cancer.    -   CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the abdomen, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. Images may be taken at three different times after the dye is injected, to get the best picture of abnormal areas in the liver. This is called triple-phase CT. A spiral or helical CT scan makes a series of very detailed pictures of areas inside the body using an x-ray machine that scans the body in a spiral path.    -   MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the liver. This procedure is also called nuclear magnetic resonance imaging (NMRI). To create detailed pictures of blood vessels in and near the liver, dye is injected into a vein. This procedure is called MRA (magnetic resonance angiography). Images may be taken at three different times after the dye is injected, to get the best picture of abnormal areas in the liver. This is called triple-phase MRI.    -   Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The picture can be printed to be looked at later.     -   Biopsy : The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. Procedures used to collect the sample of cells or tissues include the following:               -  Fine-needle aspiration biopsy : The removal of cells, tissue or fluid using a thin needle.      -  Core needle biopsy : The removal of cells or tissue using a slightly wider needle.      -  Laparoscopy : A surgical procedure to look at the organs inside the abdomen to check for signs of disease. Small incisions (cuts) are made in the wall of the abdomen and a laparoscope (a thin, lighted tube) is inserted into one of the incisions. Another instrument is inserted through the same or another incision to remove the tissue samples.          A biopsy is not always needed to diagnose adult primary liver cancer.
