Alcohol is part of many traditions and celebrations, and it’s natural to wonder how it fits into your life—especially after a cancer diagnosis. While research shows a connection between alcohol and certain types of cancer, understanding your options can help you make informed choices that feel right for you. 

Alcoholic beverages, like wine, beer, and spirits (such as brandy, gin, whiskey, and tequila), contain ethanol, a type of alcohol created when fruits and grains are fermented. The amount of ethanol varies by drink, and it’s important to know how these differences relate to health recommendations. 

In the U.S., a standard drink contains about 14 grams of ethanol. This equals: 

• 12 oz. of regular beer (5% ethanol) 

• 5 oz. of wine (12% ethanol) 

• 1.5 oz. of distilled spirits (40% or more ethanol)

Knowing the ethanol content in your drink is key because research has shown that certain levels of alcohol intake can increase cancer risk.

There is strong evidence that drinking alcohol increases the risk of several cancers, including: 

• Mouth 

• Pharynx (Throat) 

• Larynx (Throat) 

• Esophagus 

• Breast 

• Colorectal 

• Stomach 

• Liver 

Studies show that even small amounts of alcohol can contribute to cancer risk, with stronger links emerging as intake increases. For example: 

• Drinking 30 grams of ethanol daily (about two drinks) is strongly linked to colorectal cancer. 

• Drinking 45 grams or more of ethanol daily (three or more drinks) increases the risk of stomach and liver cancer.

For individuals living with cancer, research on alcohol intake shows mixed results. However, patterns of regular drinking are often associated with a higher risk of cancer recurrence and less favorable outcomes. 

This doesn’t mean you can never enjoy a drink but limiting how much and how often you drink can help support your health. If you smoke, combining alcohol with tobacco use can significantly increase cancer progression risks. 

If you’re looking for support to reduce or quit smoking or drinking, the Iris Mental Health team is here to help.

“If I don’t drink during the week, can I have two drinks a day on the weekend?” 

Skipping alcohol on weekdays and consuming multiple drinks on the weekend doesn’t lower overall cancer risk. Instead, it’s best to focus on drinking less consistently over time. 

“Is wine better than beer or liquor since it’s good for the heart?” 

Red wine does contain antioxidants and phytonutrients, but its heart-health benefits need to be balanced against the risks alcohol can pose, especially when it comes to cancer. It’s always a good idea to discuss alcohol use with your care team. 

When it comes to alcohol and cancer, drinking less is best. That doesn’t mean you have to give it up completely—enjoying a glass on a special occasion is okay for many people. Small changes, like reducing how much and how often you drink, can make a positive impact on your health. 

Your oncologist and the Iris Care Team are great resources to help you weigh the potential risks and benefits of alcohol, based on your individual situation. 

If you’re looking for alternatives or ways to reduce alcohol intake, here are some ideas: 

• Get creative with Mocktails such as: 

  • Refreshing Hibiscus 

  • Minty Cucumber Limeade 

  • Sparkling Strawberry Watermelon Limeade 

  • Ginger Pear Cider with Vanilla Bean 

• Explore low-alcohol or non-alcoholic options: 

Many beverages offer the taste and feel of your favorite drinks without the ethanol. 

• If you choose to drink, consider these tips: 

  • Stay hydrated by drinking water before and after

  • Avoid "topping off" your drink, which can make it easy to consume more than one serving

  • Don’t drink on an empty stomach—pair alcohol with food to slow its absorption
