Most Americans Mistaken About Alcohol and Cancer Risk, MD Anderson Study Finds
More than half of U.S. adults underestimate the link between alcohol and cancer risk, MD Anderson researchers say; calls grow for targeted public education.
Study finds majority unaware of alcohol and cancer risk
A new analysis from researchers at The University of Texas MD Anderson Cancer Center found that public understanding of alcohol and cancer risk is low across broad swaths of the adult population. The study reports that 52.9% of U.S. adults did not recognize that drinking alcohol increases cancer risk, leaving a large gap in basic health knowledge.
The research team warned that these misperceptions are not evenly distributed and that they may influence behavior, with many people who drink alcohol underestimating or dismissing the associated cancer risks. Experts behind the study said correcting these beliefs could be essential to preventing avoidable cancer cases.
Survey highlights who is least likely to know the risks
The analysis identified several groups with particularly low awareness of alcohol’s role in cancer development. Recent drinkers, current cigarette smokers, Black respondents, and people with lower educational attainment were among those most likely to say alcohol has no effect on cancer risk or to respond “don’t know.”
Researchers also found that people who do not believe cancer is preventable were more likely to underestimate the link between alcohol and cancer. The study team emphasized that personal beliefs about cancer play a major role in whether individuals adopt risk-reducing behaviors.
Researchers detail the scope and sample of the survey
The findings are based on responses from nearly 7,000 adults aged 18 and older who took part in the 2024 Health Information National Trends Survey. The weighted sample had a mean age of about 48, with 48.4% identifying as female, 60.7% as white, 17.5% as Hispanic and 11% as Black. Over half reported drinking alcohol within the past month and nearly 10% had a personal history of cancer.
Participants were asked how drinking alcohol affects the risk of getting cancer, with answer choices that included “increases risk,” “has no effect,” “decreases risk,” and “don’t know.” Only 37.1% selected “increases risk,” while roughly 1% chose “decreases risk,” underscoring widespread misunderstanding.
Alcohol’s classification and cancers linked to drinking
Public-health authorities classify alcohol as a known carcinogen, and scientific evidence links alcohol consumption to multiple cancer types. Alcohol is associated with cancers of the breast, liver, colorectum and several other sites, and major health bodies place it in the highest risk category alongside substances such as tobacco and asbestos.
Estimates from international health agencies indicate that alcohol accounts for a nontrivial share of cancer cases and deaths worldwide, reinforcing concerns that continued misperception could translate into preventable morbidity. Medical researchers note that risk rises with the amount and frequency of consumption, but even low levels of drinking have been connected to certain cancers.
Implications for public health messaging and prevention
The authors and outside experts argue that improving public awareness of alcohol and cancer risk could boost adherence to guidance from health authorities, including the U.S. Surgeon General’s advisory on alcohol consumption issued in 2025. Targeted education, clearer labeling, and clinician counseling were among the interventions proposed to help close the knowledge gap.
Researchers stressed that messaging should be tailored to reach demographic groups identified as least aware, using culturally appropriate channels and plain-language explanations of how alcohol contributes to cancer. They also urged coordination between health agencies, community organizations and clinicians to reinforce prevention strategies.
Calls for targeted outreach to change behavior
Health specialists say knowledge alone will not automatically change behavior, but it is a necessary first step for informed decision-making. The study’s lead investigators highlighted that people who underestimate risk are less likely to modify drinking patterns, and they called for interventions that combine awareness with supportive resources for reducing alcohol use.
Stakeholders suggested integrating alcohol-cancer risk education into routine clinical visits, cancer-prevention campaigns, and school-based health curricula. They recommended measuring the impact of outreach through follow-up surveys and tracking trends in alcohol-related cancers to evaluate whether increased awareness translates into lower incidence.
Public-health officials and researchers view the MD Anderson analysis as a practical prompt for action rather than an academic curiosity, noting that even modest shifts in population drinking behavior could prevent a measurable number of cancer cases. The study received support from the National Cancer Institute and related research funds, and its authors urged continued monitoring of public perceptions.
Efforts to bridge the awareness gap will likely require sustained investment and clear, evidence-based messages that explain the science without stigmatizing individuals.
