5 myths about alcohol and cancer risk
Key takeaways:
- Drinking any type of alcohol is linked to several cancers, including 胸部, colorectal, esophageal, oral 和 肝 cancers.
- The more you drink, the more you increase your risk of cancer, but drinking any amount of alcohol will raise your risk.
- It’s never too late to stop drinking, and quitting alcohol can reduce your cancer risk over time.
Alcohol is often a part of social gatherings, celebrations and weekly routines—but despite its prevalence, there’s a lot of confusion about how alcohol impacts your health.
From beliefs about the “safe” types of alcohol to assumptions that only frequent or heavy drinkers are at risk, misinformation can make it harder to understand how alcohol really affects your body.
That’s why we’re breaking down some of the most common myths about alcohol and cancer. Here’s what the research shows and what you can do to protect your health.
Myth #1: There is no link between alcohol and cancer.
Drinking alcohol is linked to several cancers, including 胸部, colorectal, esophageal, oral 和 肝 cancers.
If you didn’t know, you’re not alone! The National Cancer Institute (NCI) found in a 2023 study that over 60% of American adults were unaware of the link between alcohol and cancer. But drinking alcohol—in any amount—will increase your cancer risk.

Myth #2: Certain types of alcohol pose greater risk than others.
All alcoholic drinks—whether beer, wine or liquor—are linked with cancer, and no amount is considered safe.
When you drink any form of alcohol, ethanol (the form of alcohol contained in alcoholic beverages) is changed into a toxic chemical called acetaldehyde. This chemical causes damage to the DNA of your cells, preventing your body from repairing this damage, and changes how your cells grow and divide. This can lead to tumors forming.
Alcohol (of any type) can also increase the levels of some hormones, including estrogen, which can make cells divide more often. This can also increase the chance of cancer.
Myth #3: I only need to worry about cancer if I drink a lot.
While it’s true that the more you drink, the more you increase your risk of cancer, drinking any amount of alcohol will raise your risk for several types of cancer—even if it’s a light to moderate amount. It’s not the amount of alcohol causing these changes, but the alcohol itself doing the damage.
为了降低患癌症的风险,最好完全戒酒。如果你选择喝酒,如果你出生时被指定为女性,那么每天饮酒量不得超过一杯;如果你出生时被指定为男性,那么每天饮酒量不得超过两杯。
As an alternative to drinking, mocktails have become increasingly popular and are a fun way to replace your favorite beverage with an alcohol-free option.
Myth #4: Some types of alcohol, like red wine, are safe (and even good) for my health.
根据 American Heart Association, despite studies claiming a glass of red wine is good for your heart, there is not enough evidence to establish a direct relationship between alcohol consumption and improved heart health. The same goes for cancer risk, with multiple studies confirming that drinking any type of alcohol increases the risk for several types of cancer.
Drinking alcohol also raises levels of stress hormones such as cortisol, which can lead to an elevated heart rate and higher blood pressure.

Myth #5: The damage is done! I’ve been drinking for many years, so it’s probably too late to change my cancer risk.
It’s never too late to quit drinking entirely or limit the amount you drink!
For people who drank alcohol and then stopped—or those who used to drink heavily but reduced the amount—cancer risk does decline over time.
Research is ongoing to determine how long it takes for your risk to drop once you stop drinking, but the sooner you make the change, the better. And remember, avoiding alcohol altogether is the best choice for reducing cancer risk.
