Many people with primary liver cancer wonder if it’s safe to keep drinking alcohol. The fact is that alcohol is toxic to liver cells and consuming alcohol can accelerate liver damage with sometimes fatal consequences in people with this cancer. In addition, treatment options rapidly diminish when drinking continues. Patients who cannot stop consuming alcohol altogether should reach out for help from their hospital’s counselling center.
- Alcohol can act like a poison to liver cells, killing them on contact.
- Continuing to consume alcohol in the presence of primary liver cancer can cause irreparable damage.
- Alcohol can accelerate disease and reduce treatment options.
More than half a million people around the world get this cancer each year. Also referred to as hepatocellular carcinoma, it can have a variety of causes including alcohol overuse, chronic hepatitis B or C virus infection, morbid obesity with diabetes, or a metabolic disease such as hemochromatosis.
Whatever the cause, Dr. Abou-Alfa counsels primary liver cancer patients to steer clear of the bottle. “Most patients with primary liver cancer get help — once they hear what alcohol can do or has already done to their liver.”
The Reality: Stiffer than a Drink
Alcohol can act like a poison to liver cells, killing them on contact, reports Dr. Abou-Alfa. In the presence of cancerous cells already frenetically dividing, the addition of this toxin leads to ever-larger parts of the normally soft, blood-rich organ to die and turn waxy and stiff in a phenomenon known as cirrhosis. Sometimes, it’s the cirrhosis that occurs first, and then cancer follows.
In time, it becomes increasingly difficult for the liver to carry its many tasks: produce bile that help digest fats, store and release glucose (the main type of sugar in your blood), and clear harmful substances from the bloodstream, to name just a few.
Ever more clogged and hardened due to cancer or cirrhosis (or both), the liver eventually becomes overwhelmed. Fluid may start to build up in the abdomen and legs. Jaundice (yellowing of the skin and the whites of the eyes) may develop as bile clogs the bile duct — the tube that drains bile out of the liver and into the intestines. Bile then builds up in the liver and flows back into the bloodstream. Over time, a person may experience confusion, memory problems, and loss of balance.Back to top
Diminishing Treatment Options
Another risk of consuming alcohol for a person who already has liver cancer, says Dr. Abou-Alfa, is that treatment options dwindle. For example, surgery to remove cancerous liver tissue is off the table if too little of the normally functioning parts of the liver remain.
And while some people may be eligible for a liver transplant, doctors usually consider this option only if the amount of cancer in the liver is limited — and the person commits to staying alcohol free. Participation in a clinical trial may not even be a possibility if there’s concern about the liver’s impaired function and ability to process and get rid of the drugs that are being tested.
For people who had cirrhosis before they were diagnosed with liver cancer, continuing to drink can make the cirrhosis even worse. Once advanced cirrhosis sets in, localized therapies such as hepatic artery embolization — designed to block blood flow to the artery that feeds liver cancer cells — may no longer make sense. The same is true for oral drugs like sorafenib, which can block key tumor cell signals and limit the formation of new blood vessels that the cancer relies on to keep growing.
“Basically, once cirrhosis or liver cancer develops, a person’s risk of dying is much higher if he or she continues to drink,” says Dr. Abou-Alfa. “But even if a person has one or both of those diagnoses, stopping drinking has a beneficial effect. It’s never too late to stop drinking.”
MSK patients can reach out to the counselling center for help with alcohol addiction. Patients at other hospitals should talk to their doctors about additional resources available to them.Back to top
