General Information About Adult Primary Liver Cancer
Key Points for This Section
|
|
Adult primary liver cancer is a disease in which malignant (cancer) cells form in
the tissues of the liver.
The liver is one of the largest organs in the body. It has four lobes and fills the upper right side of the abdomen inside the rib cage. The liver has many important functions, including:
- Filtering harmful substances from the blood so they can be passed from the body in stools and urine.
- Making bile to help digest fats from food.
- Storing glycogen (sugar), which the body uses for energy.
This summary refers to the treatment of primary liver cancer (cancer that begins in the liver). Treatment of metastatic liver cancer, which is cancer that begins in other parts of the body and spreads to the liver, is not discussed in this summary. Primary liver cancer can occur in both adults and children. Treatment for children, however, is different than treatment for adults. (Refer to the PDQ summary on Childhood Liver Cancer Treatment 1 for more information.)
Having hepatitis or cirrhosis can affect the risk of developing adult primary liver cancer.
Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor. The following are possible risk factors for adult primary liver cancer:
- Having hepatitis B and/or hepatitis C.
- Having a close relative with both hepatitis and liver cancer.
-
Having cirrhosis.
- Eating foods tainted with aflatoxin (poison from a fungus that can grow on foods, such as grains and nuts, that have not been stored properly).
Possible signs of adult primary liver cancer include a lump or pain on the right side.
These symptoms may be caused by swelling of the liver. These and other symptoms may be caused by adult primary liver cancer or by other conditions. A doctor should be consulted if any of the following problems occur:
- A hard lump on the right side just below the rib cage.
-
Discomfort in the upper abdomen on the right side.
-
Pain around the right shoulder blade.
- Unexplained weight loss.
- Jaundice (yellowing of the skin and whites of the eyes).
- Unusual tiredness.
- Nausea.
- Loss of appetite.
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 patient’s 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.
- Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following:
- 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. Other instruments may be inserted through the same or other incisions to perform procedures such as removing organs or taking tissue samples for biopsy.
- Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The sample may be taken using a thin needle inserted into the liver during an x-ray or ultrasound. This is called a fine-needle aspiration (FNA) biopsy. The biopsy may be done during a laparoscopy.
- CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, 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.
- 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. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- 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.
Certain factors affect prognosis (chance of recovery) and treatment options.
The prognosis (chance of recovery) and treatment options depend on the following:
- The stage of the cancer (the size of the tumor, whether it affects part or all of the liver, or has spread to other places in the body).
- How well the liver is working.
- The patient’s general health, including whether there is cirrhosis of the liver.
Prognosis is also affected by alpha-fetoprotein (AFP) levels.

Glossary Terms
abdomen (AB-doh-men)
The area of the body that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs.
aflatoxin (A-fluh-TOK-sin)
A harmful substance made by certain types of mold (Aspergillus flavus and Aspergillus parasiticus) that is often found on poorly stored grains and nuts. Consumption of foods contaminated with aflatoxin is a risk factor for primary liver cancer.
alpha-fetoprotein (AL-fuh-FEE-toh-PROH-teen)
A protein normally produced by a fetus. AFP levels are usually undetectable in the blood of healthy adult men or women (who are not pregnant). An elevated level of AFP suggests the presence of either a primary liver cancer or germ cell tumor. Also called AFP.
bile
A fluid made by the liver and stored in the gallbladder. Bile is excreted into the small intestine, where it helps digest fat.
biopsy (BY-op-see)
The removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures. The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle. When a wide needle is used, the procedure is called a core biopsy. When a thin needle is used, the procedure is called a fine-needle aspiration biopsy.
blood
A tissue with red blood cells, white blood cells, platelets, and other substances suspended in fluid called plasma. Blood takes oxygen and nutrients to the tissues, and carries away wastes.
cancer (KAN-ser)
A term for
diseases in which abnormal cells divide without control and
can invade nearby tissues. Cancer cells can also spread to
other parts of the body through the blood and lymph
systems. There are several main types of cancer. Carcinoma
is cancer that begins in the skin or in tissues that line
or cover internal organs. Sarcoma is cancer that begins in
bone, cartilage, fat, muscle, blood vessels, or other
connective or supportive tissue. Leukemia is cancer that
starts in blood-forming tissue such as the bone marrow, and
causes large numbers of abnormal blood cells to be produced
and enter the blood. Lymphoma and multiple myeloma are
cancers that begin in the cells of the immune system.
Central nervous system cancers are cancers that begin in
the tissues of the brain and spinal cord.
cell (sel)
The individual unit that makes up the tissues of the body. All living things are made up of one or more cells.
cirrhosis (seh-ROH-sis)
A type of chronic, progressive liver disease in which liver cells are replaced by scar tissue.
complete blood count
A test to check the number of red blood cells, white blood cells, and platelets in a sample of blood. Also called blood cell count and CBC.
contrast material
A dye or other substance that helps show abnormal areas inside the body. It is given by injection into a vein, by enema, or by mouth. Contrast material may be used with x-rays, CT scans, MRI, or other imaging tests.
CT scan
A series of detailed pictures of areas inside the body taken from different angles. The pictures are created by a computer linked to an x-ray machine. Also called CAT scan, computed tomography scan, computerized axial tomography scan, and computerized tomography.
fine-needle aspiration biopsy (... NEE-dul as-per-AY-shun BY-op-see)
The removal of tissue or fluid with a thin needle for examination under a microscope. Also called FNA biopsy.
fungus (FUN-gus)
A plant-like organism that does not make chlorophyll. Mushrooms, yeasts, and molds are examples. The plural is fungi.
hemoglobin (HEE-moh-GLOH-bin)
The substance inside red blood cells that binds to oxygen in the lungs and carries it to the tissues.
hepatitis B virus (HEH-puh-TY-tis ... VY-rus)
A virus that causes hepatitis (inflammation of the liver). It is carried and passed to others through blood or sexual contact. Also, infants born to infected mothers may become infected with the virus.
hepatitis C virus (HEH-puh-TY-tis ... VY-rus)
A virus that causes hepatitis (inflammation of the liver). It is carried and passed to others through blood or sexual contact. Also, infants born to infected mothers may become infected with the virus.
incision (in-SIH-zhun)
A cut made in the body to perform surgery.
injection
Use of a syringe and needle to push fluids or drugs into the body; often called a "shot."
jaundice (JAWN-dis)
A condition in which the skin and the whites of the eyes become yellow, urine darkens, and the color of stool becomes lighter than normal. Jaundice occurs when the liver is not working properly or when a bile duct is blocked.
laparoscope (LA-puh-ruh-SKOPE)
A thin, tube-like instrument used to look at tissues and organs inside the abdomen. A laparoscope has a light and a lens for viewing and may have a tool to remove tissue.
laparoscopy (LA-puh-ROS-koh-pee)
A procedure that uses a laparoscope, inserted through the abdominal wall, to examine the inside of the abdomen. A laparoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease.
liver
A large organ located in the upper abdomen. The liver cleanses the blood and aids in digestion by secreting bile.
liver cancer
Primary liver cancer is cancer that forms in the tissues of the liver. Secondary liver cancer is cancer that spreads to the liver from another part of the body.
lobe
A portion of an organ, such as the liver, lung, breast, thyroid, or brain.
metastatic cancer (meh-tuh-STA-tik KAN-ser)
Cancer that has spread from the place in which it started to other parts of the body.
MRI
A procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. MRI makes better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray. MRI is especially useful for imaging the brain, the spine, the soft tissue of joints, and the inside of bones. Also called magnetic resonance imaging, NMRI, and nuclear magnetic resonance imaging.
organ
A part of the body that performs a specific function. For example, the heart is an organ.
physical examination
An exam of the body to check for general signs of disease.
platelet (PLATE-let)
A tiny piece of a cell found in the blood that breaks off from a large cell found in the bone marrow. Platelets help wounds heal and prevent bleeding by forming blood clots. Also called thrombocyte.
primary tumor
The original tumor.
prognosis (prog-NO-sis)
The likely outcome or course of a disease; the chance of recovery or recurrence.
protein (PRO-teen)
A molecule made up of amino acids that are needed for the body to function properly. Proteins are the basis of body structures such as skin and hair and of substances such as enzymes, cytokines, and antibodies.
red blood cell
A cell that carries oxygen to all parts of the body. Also called erythrocyte and RBC.
risk factor
Something that may increase the chance of developing a disease. Some examples of risk factors for cancer include age, a family history of certain cancers, use of tobacco products, certain eating habits, obesity, lack of exercise, exposure to radiation or other cancer-causing agents, and certain genetic changes.
serum tumor marker test
A blood test that measures the amount of substances called tumor markers (or biomarkers). Tumor markers are released into the blood by tumor cells or by other cells in response to tumor cells. A high level of a tumor marker may be a sign of cancer.
sonogram (SON-o-gram)
A computer picture of areas inside the body created by bouncing high-energy sound waves (ultrasound) off internal tissues or organs. Also called ultrasonogram.
stage
The extent of a cancer in the body. Staging is usually based on the size of the tumor, whether lymph nodes contain cancer, and whether the cancer has spread from the original site to other parts of the body.
stool
The material in a bowel movement. Stool is made up of food that was not digested, bacteria, mucus, and cells from the intestines. Also called feces.
symptom
An indication that a person has a condition or disease. Some examples of symptoms are headache, fever, fatigue, nausea, vomiting, and pain.
tissue (TISH-oo)
A group or layer of cells that work together to perform a specific function.
tumor (TOO-mer)
An abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Tumors may be benign (not cancer), or malignant (cancer). Also called neoplasm.
tumor marker (TOO-mer ...)
A substance that may be found in tumor tissue or released from a tumor into the blood or other body fluids. A high level of a tumor marker may mean that a certain type of cancer is in the body. Examples of tumor markers include CA 125 (in ovarian cancer), CA 15-3 (in breast cancer), CEA (in ovarian, lung, breast, pancreas, and gastrointestinal tract cancers), and PSA (in prostate cancer).
ultrasound (UL-truh-SOWND)
A procedure in which high-energy sound waves are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasonography.
urine (YOOR-in)
Fluid containing water and waste products. Urine is made by the kidneys, stored in the bladder, and leaves the body through the urethra.
vein (vayn)
A blood vessel that carries blood to the heart from tissues and organs in the body.
white blood cell
A type of immune cell. Most white blood cells are made in the bone marrow and are found in the blood and lymph tissue. White blood cells help the body fight infections and other diseases. Granulocytes, monocytes, and lymphocytes are white blood cells. Also called leukocyte and WBC.
x-ray
A type of high-energy radiation. In low doses, x-rays are used to diagnose diseases by making pictures of the inside of the body. In high doses, x-rays are used to treat cancer.
