The liver is located in the right side of the abdomen. It stores and metabolizes nutrients. It also filters and stores blood. Liver cancer is the growth of cancer cells in the liver.
Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor. The term cancer refers to malignant tumors. These tumors can invade nearby tissue and spread to other parts of the body.
The cause of liver cancer is not known. Research shows that certain risk factors are associated with the disease.
Factors that may increase you chance of liver cancer include:
- Sex: male
- Age: 40 and older
- Infection with the hepatitis B virus or the hepatitis C virus
- Formation of scar tissue in the liver, also known as cirrhosis
- Excessive alcohol consumption
- Exposure to an infectious agent, such as a liver fluke, which are found in southern Pacific countries
- Hemochromatosis —abnormal collection of iron in body tissues
- Hereditary metabolic disorders such as alpha-antitrypsin (AAT) deficiency and tyrosinemia
- Exposure to certain chemicals:
- Aflatoxin—a substance made by a fungus that often infects wheat, peanuts, soybeans, corn, and rice in tropical and subtropical regions
- Vinyl chloride and thorium dioxide—chemicals that are strictly controlled
- Anabolic steroids—male hormones sometimes given for medical reasons, but also taken by athletes to increase strength
- Arsenic —a toxic chemical

Symptoms of liver cancer in the early stages are vague. They often go unnoticed.
Liver cancer can cause the following symptoms:
- Loss of appetite
- Unexplained weight loss
- Abdominal pain and swelling
- Dark urine
- Excessive itchiness of the skin
- Confusion and increased sleepiness
- Yellowing of the skin and/or the whites of the eye
These may also be caused by other, less serious health conditions. See a doctor if you have these symptoms.
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Your bodily fluids may be tested. This can be done with:
- Blood tests
Your doctor may need to view images of your bodily structures. This can be done with:
Once liver cancer is found, staging tests are done. This will help find out if the cancer has spread and, if so, to what extent. Surgery is the only curative procedure in liver cancer. Chemotherapy and radiation therapy can reduce symptoms associated with the cancer. They are not considered curative by themselves.
- Surgery—removal of the cancerous tumor and nearby tissue, and possibly nearby lymph nodes
At UVA, we're performing liver resection surgery on patients with liver cancer, such as hepatocellular cancer. It's also done in those with colon cancer that's spread to the liver and patients with liver cysts, adenomas or hemangiomas. Find out more about this treatment option.
- Cryosurgery—destroys tumors by freezing them with a metal probe
- Ethanol ablation—kills cancer cells by injecting alcohol directly into the tumor
therapy —the use of radiation to kill cancer cells and
shrink tumors. Radiation may be:
- External radiation therapy—Radiation directed at the liver from a source outside the body
- Internal radiation therapy—Radioactive materials placed into the liver in or near the cancer cells
- Chemotherapy —drugs enter the bloodstream and travel through the body to kill mostly cancer cells and some healthy cells; may be given by pill, injection, and via a catheter directly into the liver
- Sorafenib (Nexavar)—a new class of therapies targeting vascular endothelial growth factor receptor (VEGF); used for advanced liver cancer, in one study improved overall survival from median 7.9 months to 10.7 months
- Biological therapy—the use of medications or substances made by the body to increase or restore the body's natural defenses against cancer; also called biological response modifier (BRM) therapy
To reduce your risk of getting liver cancer:
- If you use needles to inject medication or drugs, always use a clean needle. Do not share needles with anyone.
- Use condoms when having sexual intercourse if you or your partner is not in a monogamous relationship or if you don't know if your partner has hepatitis.
- Have children vaccinated against hepatitis B.
