We all know too much alcohol can cause hangovers, even headaches. But did you know that it can also cause cancer? A new study has revealed that over half of American adults are unaware that drinking alcohol raises the risk of developing cancer, and the people who drink most are often the least aware.

Researchers from the University of Texas MD Anderson Cancer Center surveyed nearly 7,000 adults across the United States. The results were eye-opening: only about 37 per cent of people said they knew alcohol increases the risk of cancer, while more than half said they didn’t know, and one per cent even thought it might lower the risk.

Dr Sanjay Shete, who led the study, said the results were worrying. “It’s concerning that the people who drink alcohol are the ones most likely to believe it has no effect on cancer risk. People’s beliefs have a big influence on the choices they make. If we can correct these misunderstandings, we could help reduce the number of alcohol-related cancers,” he explained.

What the study found

Drinkers least aware: People who drink regularly are less likely to know alcohol increases cancer risk.

Certain groups more at risk of misunderstanding: Smokers and those with less formal education were less likely to be aware of the link.

Beliefs matter: People who thought cancer couldn’t be prevented were also less likely to believe alcohol affects cancer risk.

Alcohol is a proven carcinogen: The World Health Organization has long classified alcohol as a Group 1 carcinogen — the same category as tobacco, asbestos, and radiation.

Seven types of cancer linked: Alcohol is known to contribute to breast, liver, and bowel cancer, among others.

Global impact: According to the National Institutes of Health, drinking alcohol is responsible for around 5.5 percent of new cancer cases and 5.8 percent of cancer deaths worldwide.

Experts say that raising public awareness about alcohol’s link to cancer could encourage healthier habits. If more people understood the risks, they might choose to drink less, which could prevent many cases of cancer every year. The U.S. Surgeon General’s new 2025 guidelines also stress the importance of limiting alcohol intake for better long-term health.

Dr Shete added, “Awareness is key. When people understand the risks, they can make better decisions for themselves and their families.”
