Cancer is a disease in which cells in the body grow out of control. When cancer starts in the liver, it is called liver cancer. Each year in the United States, about 33,000 people get liver cancer, and about 27,000 people die from the disease. The percentage of Americans who get liver cancer has been rising for several decades.
What Is the Liver?
The liver is the largest organ in the human body, located on the upper right side of the body, behind the lower ribs. The liver does many jobs, including—
- Storing nutrients.
- Removing waste products and worn-out cells from the blood.
- Filtering and processing chemicals in food, alcohol, and medications.
- Producing bile, a solution that helps digest fats and eliminate waste products.
What Causes Liver Cancer?
Other behaviors and conditions that increase risk for getting liver cancer are—
- Excessive alcohol use.
- Cirrhosis (scarring of the liver, which can also be caused by hepatitis and alcohol use).
- Having hemochromatosis, a condition where the body takes up and stores more iron than it needs.
- Eating foods that have aflatoxin (a fungus that can grow on foods, such as grains and nuts that have not been stored properly).
What Are the Symptoms of Liver Cancer?
In its early stages, liver cancer may not have symptoms that can be seen or felt. However, as the cancer grows larger, people may notice one or more of these common symptoms. It’s important to remember that these symptoms could also be caused by other health conditions. If you have any of these symptoms, talk to your doctor.
Liver cancer symptoms may include—
- Discomfort in the upper abdomen on the right side.
- A swollen abdomen.
- A hard lump on the right side just below the rib cage.
- Pain near the right shoulder blade or in the back.
- Jaundice (yellowing of the skin and whites of the eyes).
- Easy bruising or bleeding.
- Unusual tiredness.
- Nausea and vomiting.
- Loss of appetite.
- Weight loss for no known reason.
How Can I Reduce My Risk for Liver Cancer?
You can lower your risk of getting liver cancer in the following ways—
- Get vaccinated against Hepatitis B. The Hepatitis B vaccine is recommended for all infants at birth and for adults who may be at increased risk.
- Get tested for Hepatitis C, and get medical care if you have it.
- Avoid drinking too much alcohol.
The Data Visualizations tool makes it easy for anyone to explore and use the latest official federal government cancer data from United States Cancer Statistics. It includes the latest cancer data covering 100% of the U.S. population.
A CDC studyexternal icon found that the number of people who are alive five years after being told they have liver cancer is low. During 2004 to 2009—
- About 26% of liver cancer patients were alive five years after diagnosis if the cancer had not spread beyond the liver.
- About 10% were alive five years after diagnosis if the cancer had spread only to tissues or lymph nodes near the liver.
- About 4% were alive five years after diagnosis if the cancer had spread from the liver to other parts of the body.
