Alcohol and Liver Cancer
In This Article
What is Liver Cancer?
Primary liver cancer is a type of cancer that starts in the liver. It is a serious, life-threatening condition. According to the Centers for Disease Control and Prevention (CDC), nearly 19,000 men and 9,000 women die each year because of liver cancer.
The exact cause of liver cancer has yet to be determined. However, alcohol is a definite risk factor, among many others. Understanding how these factors cause liver cancer can help significantly lower one's risk of developing liver cancer. Additionally, knowing what signs and symptoms to watch out for can prompt early diagnosis and treatment.

Can Alcohol Cause Liver Cancer?
Liver cancer, or hepatocellular carcinoma, is often linked to excessive consumption of alcohol.
While alcohol consumption does not directly cause liver cancer, drinking alcohol can cause long-term liver damage and scarring (known as liver cirrhosis). Thus, liver cancer and alcohol are closely related.
It takes time to develop long-term liver damage and scarring of liver tissue with heavy alcohol use. The damage can actually cause changes in the DNA of the liver cells, which is what can eventually lead to cancer.
How Does Alcohol Increase Cancer Risk?
Your body breaks down alcohol into a chemical called acetaldehyde, which damages your DNA and then stops your body from repairing that damage. This damage can stunt cells’ normal growth and inhibit their normal function. When cells grow out of control, they can create cancer tumors.
Therefore, the less alcohol you consume, the lower your risk of developing cancer, not just liver cancer. Alcohol can increase one’s risk of developing several types of cancer, such as the following:
- Mouth and throat cancer
- Voicebox (larynx) cancer
- Esophageal cancer
- Colon and rectum cancer
- Breast cancer (in women)
Symptoms of Liver Cancer
Liver cancer symptoms will vary among different cancer patients, but some of the most common liver cancer symptoms include the following:
- Liver pain after drinking
- Nausea or vomiting with or without drinking
- Unexplained weight loss
- Loss of appetite
- Feeling full after small meals
- Easy bruising or bleeding
- Unusual tiredness
- An enlarged liver on the right side
- An enlarged spleen on the left side
- Swelling or fluid build-up in the abdomen
- Jaundice (yellowing of the skin and eyes)
Risk Factors Associated with Alcohol-Related Liver Cancer
Several factors greatly increase a person's risk of developing alcohol-related cancer. Here are some of them:
- Binge Drinking — Binge drinking is when a person consumes a large amount of alcohol in a short period of time. This can lead to fatty liver disease and, sometimes, alcoholic hepatitis.
- Excessive Alcohol Consumption — The recommended daily alcohol intake is 2 drinks for men and 1 drink for women. Excessive alcohol consumption is when a person exceeds these recommended limits. This can cause hepatitis and cirrhosis.
- Obesity — Obesity causes changes in the body that oftentimes lead to liver cancer, among many other types of cancer. It can trigger inflammation inside the body which puts an unnecessary amount of workload on the liver. Compounded by excessive alcohol consumption, the liver will have to work hard to metabolize alcohol. This can lead to liver cancer.
- Being Female — Women are more prone to developing alcohol-related liver cancer because, compared to men, women are more vulnerable to alcohol's harmful effects.
- Genetics — People with a family history of alcohol abuse have a higher tendency of becoming alcoholics themselves. These puts them at an increased risk of developing alcohol-related liver cancer.
Several other conditions also put people at a higher risk of cancer in the liver, such as hepatitis B and hepatitis C.
Other Alcohol-Related Liver Conditions
Alcohol can cause other damage to your liver, beyond increasing your risk of developing cancer. Other alcohol-related liver conditions include the following:
- Alcoholic Liver Disease
- Alcoholic Hepatitis
- Alcoholic Fatty Liver Disease
- Bile Duct Cancer
- Primary Sclerosing Cholangitis
- Liver Failure
Alcohol and Liver Cancer Statistics
Liver cancer is on the rise. Here are some statistics about alcohol and liver cancer of which you should be aware:
- More than 800,000 people around the world are diagnosed with liver cancer every year.
- Liver cancer affects about 33,000 people each year in the United States alone, claiming the lives of about 27,000.
- Drinking alcohol increases your risk of developing liver cancer two-fold.
- The use of alcohol accounts for about six percent of all cancers.
- Alcohol use accounts for about four percent of all cancer deaths across the country.
Alcohol and Liver Cancer FAQs
Here are answers to some of the most commonly asked questions about the association between alcohol and liver cancer.
Can I drink alcohol with liver cancer?
No matter the amount of alcohol, it’s best to avoid drinking alcohol with liver cancer. While there’s a gamut of cancer research surrounding the link between heavy drinking and the risk of developing certain diseases, studies about alcohol use during cancer treatment or after cancer are largely inconclusive.
Alcohol use may raise the risk of recurring cancer or developing other types of cancer. Likewise, alcohol can also make some symptoms of certain cancers worse. For example, alcohol can cause nausea and vomiting, which are symptoms of liver cancer.
Liver cancer patients should check with their healthcare partners about the safety of drinking alcohol in their given circumstances.
How many people get liver cancer from heavy alcohol use?
Several risk factors can increase one’s chances of developing liver cancer. This makes it hard to pinpoint exactly how many people get liver cancer from consuming alcoholic drinks. That said, heavy alcohol use is linked to a doubled risk of liver cancer. The more one drinks, the bigger the risk of developing liver cancer, which puts heavy drinkers in danger.
What is the survival rate of liver cancer with cancer treatment?
About 26 percent of those diagnosed with liver cancer survive five or more years if the cancer did not spread beyond their livers. About 10 percent were alive after five years of their diagnosis if the cancer did spread to tissue or lymph nodes around the liver, and about four percent were alive five years after if it’d spread to other parts of the body.
Cancer treatment can increase the survival rate, however. The five-year survival rate for people diagnosed with early-stage liver cancers and who have a liver transplant is about 60 to 70 percent.
