Symptoms

Most people don't have signs and symptoms in the early stages of primary liver cancer. When signs and symptoms do appear, they may include:

• Losing weight without trying
• Loss of appetite
• Upper abdominal pain
• Nausea and vomiting
• General weakness and fatigue
• Abdominal swelling
• Yellow discoloration of your skin and the whites of your eyes (jaundice)
• White, chalky stools

When to see a doctor

Make an appointment with your doctor if you experience any signs or symptoms that worry you.

Causes

It's not clear what causes most cases of liver cancer. But in some cases, the cause is known. For instance, chronic infection with certain hepatitis viruses can cause liver cancer.

Liver cancer occurs when liver cells develop changes (mutations) in their DNA — the material that provides instructions for every chemical process in your body. DNA mutations cause changes in these instructions. One result is that cells may begin to grow out of control and eventually form a tumor — a mass of cancerous cells.

Prevention

Reduce your risk of cirrhosis

Cirrhosis is scarring of the liver, and it increases the risk of liver cancer. You can reduce your risk of cirrhosis if you:

• Drink alcohol in moderation, if at all. If you choose to drink alcohol, limit the amount you drink. For women, this means no more than one drink a day. For men, this means no more than two drinks a day.
• Maintain a healthy weight. If your current weight is healthy, work to maintain it by choosing a healthy diet and exercising most days of the week. If you need to lose weight, reduce the number of calories you eat each day and increase the amount of exercise you do. Aim to lose weight slowly — 1 or 2 pounds (0.5 to 1 kilograms) each week.
• Use caution with chemicals. Follow instructions on chemicals you use at home or at work.

Get vaccinated against hepatitis B

You can reduce your risk of hepatitis B by receiving the hepatitis B vaccine, which provides more than 90 percent protection for both adults and children. The vaccine can be given to almost anyone, including infants, older adults and those with compromised immune systems.

Take measures to prevent hepatitis C

No vaccine for hepatitis C exists, but you can reduce your risk of infection.

• Know the health status of any sexual partner. Don't engage in unprotected sex unless you're certain your partner isn't infected with HBV, HCV or any other sexually transmitted infection. If you don't know the health status of your partner, use a condom every time you have sexual intercourse.
• Don't use intravenous (IV) drugs, but if you do, use a clean needle. Reduce your risk of HCV by not injecting illegal drugs. But if that isn't an option for you, make sure any needle you use is sterile, and don't share it. Contaminated drug paraphernalia is a common cause of hepatitis C infection. Take advantage of needle-exchange programs in your community and consider seeking help for your drug use.
• Seek safe, clean shops when getting a piercing or tattoo. Needles that may not be properly sterilized can spread the hepatitis C virus. Before getting a piercing or tattoo, check out the shops in your area and ask staff members about their safety practices. If employees at a shop refuse to answer your questions or don't take your questions seriously, take that as a sign that the facility isn't right for you.

Ask your doctor about liver cancer screening

For the general population, screening for liver cancer hasn't been proved to reduce the risk of dying of liver cancer, so it isn't generally recommended. The American Association for the Study of Liver Diseases recommends liver cancer screening for those thought to have a high risk, including people who have:

• Hepatitis B and one or more of the following apply: are Asian or African, have liver cirrhosis, or have a family history of liver cancer
• Hepatitis C infection and liver cirrhosis
• Liver cirrhosis from other causes, such as an autoimmune disease, excessive alcohol use, nonalcoholic fatty liver disease and inherited hemochromatosis
• Primary biliary cirrhosis

Discuss the pros and cons of screening with your doctor. Together you can decide whether screening is right for you based on your risk. Screening typically involves an ultrasound exam every six months.

Alternative medicine

Alternative treatments may help control pain in people with advanced liver cancer. Your doctor will work to control pain with treatments and medications. But sometimes your pain may persist or you may want to avoid the side effects of pain medications.

Ask your doctor about alternative treatments that may help you cope with pain, such as:

• Acupressure
• Acupuncture
• Deep breathing
• Listening to music (music therapy)
• Massage

Coping and support

Learning you have any life-threatening illness can be devastating. Each person finds his or her own ways of coping with a diagnosis of liver cancer. Although there are no easy answers for people dealing with liver cancer, the following suggestions may be of help:

• Learn enough about liver cancer to make decisions about your care. Ask your doctor about your liver cancer, including the stage of your cancer, your treatment options and, if you like, your prognosis. As you learn more about liver cancer, you may become more confident in making treatment decisions.
• Keep friends and family close. Keeping your close relationships strong will help you deal with your liver cancer. Friends and family can provide the practical support you'll need, such as helping take care of your house if you're in the hospital. And they can serve as emotional support when you feel overwhelmed by cancer.

• Find someone to talk with. Find a good listener with whom you can talk about your hopes and fears. This may be a friend or family member. The support of a counselor, medical social worker, clergy member or cancer survivors group also may be helpful.

  Ask your doctor about support groups in your area. Or check your phone book, library or a cancer organization, such as the National Cancer Institute or the American Cancer Society.

• Make plans for the unknown. Having a life-threatening illness, such as cancer, requires you to prepare for the possibility that you may die. For some people, having a strong faith or a sense of something greater than themselves makes it easier to come to terms with a life-threatening illness.

  Ask your doctor about advance directives and living wills to help you plan for end-of-life care, should you need it.

Preparing for an appointment

If you think you may have liver cancer, you're likely to start by seeing your family doctor. If your doctor suspects you may have liver cancer, you may be referred to a doctor who specializes in diseases of the liver (hepatologist) or to a doctor who specializes in treating cancer (oncologist).

Because appointments can be brief, and because there's often a lot of ground to cover, it's a good idea to be well-prepared. Here's some information to help you get ready and what to expect from your doctor.

What you can do

• Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there's anything you need to do in advance, such as restrict your diet.
• Write down any symptoms you're experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
• Write down key personal information, including any major stresses or recent life changes.
• Make a list of all medications, as well as any vitamins or supplements, that you're taking.
• Consider taking a family member or friend along. Sometimes it can be difficult to remember all the information provided during an appointment. Someone who accompanies you may remember something that you missed or forgot.
• Write down questions to ask your doctor.

Your time with your doctor is limited, so preparing a list of questions will help you make the most of your time together. List your questions from most important to least important in case time runs out. For liver cancer, some basic questions to ask your doctor include:

• What type of liver cancer do I have?
• What is the stage of my liver cancer?
• What does my pathology report say? Can I have a copy of the pathology report?
• Will I need more tests?
• What are my treatment options?
• What are the potential side effects of each treatment option?
• Is there one treatment you recommend over the others?
• How will my treatment affect my daily life?
• How much time can I take to make my decision about liver cancer treatment?
• Should I seek a second opinion?
• Should I see a liver cancer specialist? What will that cost, and will my insurance cover it?
• Are there brochures or other printed material that I can take with me? What websites do you recommend?

In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask additional questions during your appointment.

What to expect from your doctor

Your doctor is likely to ask you a number of questions. Being ready to answer them may allow more time later to cover other points you want to address. Your doctor may ask:

• When did you first begin experiencing symptoms?
• Have your symptoms been continuous or occasional?
• How severe are your symptoms?
• What, if anything, seems to improve your symptoms?
• What, if anything, appears to worsen your symptoms?

Overview

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. Hepatocellular carcinoma occurs most often in people with chronic liver diseases, such as cirrhosis caused by hepatitis B or hepatitis C infection.

Risk factors

The risk of hepatocellular carcinoma, the most common type of liver cancer, is higher in people with long-term liver diseases. It's also higher if the liver is scarred by infection with hepatitis B or hepatitis C. Hepatocellular carcinoma is more common in people who drink large amounts of alcohol and who have an accumulation of fat in the liver.

Diagnosis

Tests and procedures used to diagnose hepatocellular carcinoma include:

• Blood tests to measure liver function
• Imaging tests, such as CT and MRI
• Liver biopsy, in some cases, to remove a sample of liver tissue for laboratory testing

Treatment

Which treatment is best for you will depend on the size and location of your hepatocellular carcinoma, how well your liver is functioning, and your overall health.

Hepatocellular carcinoma treatments include:

• Surgery. Surgery to remove the cancer and a margin of healthy tissue that surrounds it may be an option for people with early-stage liver cancers who have normal liver function.
• Liver transplant surgery. Surgery to remove the entire liver and replace it with a liver from a donor may be an option in otherwise healthy people whose liver cancer hasn't spread beyond the liver.
• Destroying cancer cells with heat or cold. Ablation procedures to kill the cancer cells in the liver using extreme heat or cold may be recommended for people who can't undergo surgery. These procedures include radiofrequency ablation, cryoablation, and ablation using alcohol or microwaves.
• Delivering chemotherapy or radiation directly to cancer cells. Using a catheter that's passed through your blood vessels and into your liver, doctors can deliver chemotherapy drugs (chemoembolization) or tiny glass spheres containing radiation (radioembolization) directly to the cancer cells.
• Radiation therapy. Radiation therapy using energy from X-rays or protons may be recommended if surgery isn't an option. A specialized type of radiation therapy, called stereotactic body radiotherapy (SBRT), involves focusing many beams of radiation simultaneously at one point in your body.
• Targeted drug therapy. Targeted drugs attack specific weaknesses in the cancer cells, and they may help slow the progression of the disease in people with advanced liver cancers.
• Immunotherapy. Immunotherapy drugs use your body's germ-fighting immune system to attack the cancer cells. Immunotherapy may be an option for treating advanced liver cancer.
• Clinical trials. Clinical trials give you a chance to try new liver cancer treatments. Ask your doctor whether you're eligible to participate in a clinical trial.
