Should You Stop Drinking Alcohol to Reduce Your Cancer Risk?
For years, many Americans have heard that moderate drinking—especially a glass of red wine with dinner—might actually be good for their health. But when we look specifically at cancer prevention, the message is becoming much clearer: less alcohol is better, and no alcohol provides the lowest alcohol-related cancer risk.
Alcohol is classified as a Group 1 carcinogen, meaning there is sufficient evidence that it can cause cancer in humans. This is the same classification category used for other established carcinogens, although being in the same category does not mean they all carry the same degree of risk.
Alcohol consumption has been linked to at least seven types of cancer, including cancers of the:
- Breast
• Colon and rectum
• Liver
• Mouth
• Throat
• Voice box
• Esophagus
So how does something as common as a glass of wine, beer or cocktail contribute to cancer?
When we drink alcohol, our bodies break ethanol down into acetaldehyde, a toxic chemical that can damage DNA. Alcohol can also contribute to oxidative stress and inflammation, interfere with the body’s ability to absorb certain nutrients, and alter hormone levels. Increased estrogen is one reason alcohol is particularly important when discussing breast cancer risk.
One of the biggest misconceptions is that cancer risk occurs only among heavy drinkers.
That’s not necessarily true.
Cancer risk generally increases as alcohol consumption increases, but even relatively low levels of drinking have been associated with increased risk for certain cancers. This is particularly important for women because even modest alcohol consumption has been associated with a higher risk of breast cancer.
Does this mean that having an occasional glass of wine will cause cancer? No.
Cancer is complicated. Age, genetics, tobacco exposure, body weight, physical activity, diet, environmental exposures and many other factors influence an individual’s risk. Alcohol is simply one modifiable risk factor we can control.
For people who enjoy alcohol, this doesn’t have to be an all-or-nothing conversation. Drinking less reduces exposure. Alcohol-free beer and wine, sparkling water with fruit, kombucha and creative mocktails can provide alternatives in social situations.
But if your question is simply, “What amount of alcohol gives me the lowest alcohol-related cancer risk?”
The answer is none.
That doesn’t mean everyone who drinks alcohol will develop cancer, nor does it mean eliminating alcohol guarantees you won’t. It means that alcohol contributes to cancer risk, and removing that exposure is one step you can take to reduce your overall risk.
In the Past, the Dietary Guidelines Set a Daily Amount
As a Registered Dietitian, I have spent more than five decades encouraging people to look at the choices they make every day. We cannot control every cancer risk factor, but we can make informed decisions about the ones we can control.
When it comes to alcohol and cancer prevention, perhaps the simplest message is:
If you don’t drink, don’t start for health reasons. If you do drink, drinking less is better. And if you want to minimize your alcohol-related cancer risk, choosing not to drink is the lowest-risk option.
