Cancer that starts in the liver is called liver cancer (or Hepatocellular carcinoma), and alcohol consumption can increase one’s risk of developing this life-threatening disease.
While alcohol consumption does not necessarily directly cause liver cancer, drinking alcohol can cause long-term liver damage and scarring (known as liver cirrhosis), ultimately leading to liver cancer. It takes time to cause long-term liver damage and scarring of liver tissue with heavy alcohol use. And that damage can actually cause changes in the DNA of the liver cells, which is what can eventually lead to cancer.
While moderate alcohol intake can cause liver damage, as well, heaving drinking and alcohol abuse significantly increase one’s risk of developing liver cancer. Several other conditions also put people at a higher risk of developing liver cancer, such as the viruses hepatitis B and hepatitis C.
Health authorities recommend that, to practice liver cancer prevention, people who choose to drink alcoholic beverages should limit their intake. Men shouldn’t consume more than two drinks per day, while women shouldn’t consume more than a single drink per day.
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 — and not just liver cancer. Alcohol can increase one’s risk of developing several types of cancer, such as the following:
Liver cancer symptoms will vary across cancer patients, but some of the most common liver cancer symptoms include the following:
Alcohol can cause other damage to your liver, beyond increasing your risk of developing cancer. Other alcohol-related liver conditions include the following:
Liver cancer is on the rise. Here are some statistics about alcohol and liver cancer of which you should be aware:
Here are answers to some of the most commonly asked questions about the association between alcohol and 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, symptoms of liver cancer.
Patients should check with their healthcare partners about the safety of drinking alcohol in their given circumstances.
Several risk factors can increase one’s chances of developing liver cancer, which makes it hard to pinpoint exactly how many people get liver cancer from consuming alcoholic drinks in particular. That said, heavy alcohol use is linked to doubled risk of liver cancer. The more one drinks, the bigger their risk of developing liver cancer, which puts heavy drinkers in danger.
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 who are diagnosed with early-stage liver cancers and have a liver transplant is about 60 to 70 percent.
