Researchers say alcohol plays a meaningful role in the development of several cancers

Even moderate drinking raises cancer risk: A sweeping new review finds that how often and how much Americans drink alcohol directly affects their risk of developing several common cancers.

Some groups face higher danger: Race, income, existing health conditions, and genetics can make alcohols cancer risks even greater, even at similar or lower levels of drinking.

Healthy lifestyle choices can help: Following cancer prevention guidelines, including limiting alcohol, is linked to lower cancer risk and better survival.
The holidays are a time of continuous celebration and that can lead to a time when alcohol often flows more freely. Not to be a buzz kill, but new research is offering a sobering reminder: drinking alcohol, even in moderation, can raise the risk of cancer.
A major new analysis from researchers at Florida Atlantic Universitys Charles E. Schmidt College of Medicine examined decades of research to better understand how alcohol consumption affects cancer risk in U.S. adults.
The findings confirm what scientists have long suspected but the public often underestimates alcohol plays a meaningful role in the development of several cancers, and the risk increases as drinking increases.
What the researchers found
The research team reviewed 62 studies, involving anywhere from small groups of 80 people to massive populations nearing 100 million participants. Their goal was to see how different drinking patterns mild, moderate, and heavy affect cancer risk, and how factors like obesity, diabetes, and liver disease influence outcomes.
The results were clear: both how often people drink and how much they drink matter. Alcohol consumption was strongly linked to higher risk of several cancers, including:
-
Breast
-
Colorectal
-
Liver
-
Oral and throat (laryngeal)
-
Esophageal
-
Gastric (stomach)
Alcohol didnt just raise the chances of developing cancer it also worsened outcomes. People with alcohol-related liver disease, for example, were more likely to be diagnosed with advanced liver cancer and had lower survival rates.
Risk isnt the same for everyone
One of the most important takeaways is that alcohol-related cancer risk isnt evenly distributed.
Higher levels of drinking were especially dangerous for African Americans, people with genetic risk factors, and those living with obesity or diabetes.
Socioeconomic factors such as income, education, and access to healthcare also played a major role, leaving some lower-income and certain racial or ethnic groups more vulnerable even when they drank the same amount or less than others.
Gender differences emerged as well. Frequent drinking increased cancer risk more clearly in men, while episodic heavy or binge drinking appeared to be particularly risky for women.
Smoking made things worse. Combining alcohol and tobacco significantly amplified cancer risk, although the degree of risk varied by sex and drinking pattern.
Does the type of alcohol matter?
In some cases, yes. The review found that beer and white wine were linked to higher risk for certain cancers, while liquor was not consistently associated with increased risk. However, researchers caution that no form of alcohol can be considered safe when it comes to cancer.
Other factors that strengthened the alcoholcancer link included early age of first drink, family history of cancer, UV exposure (in melanoma risk), hormone use, poor diet, low physical activity, and infections such as hepatitis B or C, HPV, HIV, or H. pylori.
Why alcohol raises cancer risk
Biologically, alcohol affects the body in several harmful ways. It breaks down into acetaldehyde, a toxic compound that can damage DNA. Alcohol also disrupts hormone levels, increases oxidative stress, weakens the immune system, and helps other carcinogens enter the body more easily. When combined with chronic illnesses or unhealthy lifestyle habits, these effects can accelerate cancer development.
What can reduce risk?
There is some encouraging news. People who followed American Cancer Society guidelines limiting alcohol intake, maintaining a healthy weight, staying physically active, and avoiding smoking had lower cancer risk and mortality.
The researchers say this highlights the importance of viewing cancer prevention as more than just cutting back on drinks. Addressing underlying health conditions, improving diet and activity levels, and reducing social and environmental barriers are all part of lowering long-term risk.
