(Press-News.org) More than half of American adults misunderstand or underestimate the link between alcohol consumption and cancer
Alcohol drinkers are especially likely to believe that drinking has no effect on cancer risk
Correcting these misbeliefs may strengthen adherence to U.S. Surgeon General’s alcohol consumption guidelines to lower cancer risk
HOUSTON, OCTOBER 30, 2025 – Despite clear evidence linking alcohol use to increased cancer risks, public awareness of this connection remains low in the U.S., according to new research from The University of Texas MD Anderson Cancer Center. Researchers found that more than half of American adults (52.9%) did not know alcohol affects cancer risk.
The cross-sectional study, published today in JAMA Oncology, revealed 37.1% of U.S. adults do understand there is a correlation between cancer risk and drinking, and 1% believed that drinking decreased cancer risk. People who had recently consumed alcohol, or who believed that cancer isn’t fatal or preventable, were more likely to think that drinking alcohol doesn’t influence cancer risk, the study also found.
“It’s concerning that people who drink alcohol are the ones most likely to believe it has no effect on cancer risk,” said lead author, Sanjay Shete, Ph.D., professor of Biostatistics and Epidemiology, and Betty B. Marcus Chair in Cancer Prevention. “Given people’s beliefs play a critical role in whether they choose healthier behaviors, we need to work on correcting these misperceptions, which could be essential to reducing the growing burden of alcohol-related cancers.”
According to the study, what may impact a person’s view of alcohol and cancer risk?
While it is known that individuals’ beliefs strongly influence their willingness to adopt healthier behaviors, few studies have examined this on a national scale. Researchers found that the prevalence of beliefs varied according to certain health-behavioral factors.
Current cigarette smokers, Black individuals, those with lower education levels (below a college or high school level), and those who do not believe cancer is preventable were more likely not to know that alcohol influences cancer risk.
What do we know about alcohol and cancer risk?
According to the World Health Organization, alcohol is classified as a Group 1 carcinogen, the same category as tobacco, asbestos and radiation. Drinking alcohol has been linked to at least seven types of cancer. About 5.5% of all new cancer diagnoses and 5.8% of all deaths from cancer are attributed to drinking alcohol, according to the National Institutes of Health (NIH).
Addressing misbeliefs could reinforce individual compliance with alcohol consumption guidelines, particularly those recently endorsed by the U.S. Surgeon General in his 2025 advisory, and may help mitigate preventable cancer-related deaths.
How was the study conducted?
In this analysis, researchers looked at responses from almost 7,000 Americans over the age of 18 (mean age 48) from the 2024 Health Information National Trends Survey data. Almost half were female (48.4%), 60.7% were white, 17.5% were Hispanic and 11% were Black. More than half of respondents had consumed alcohol in the last month. Nearly 10% had a personal cancer history.
The belief about the effect of alcohol on cancer risk was measured with the question: “In your opinion, how does drinking alcohol affect the risk of getting cancer?” Possible responses to this question were: "decreases the risk of cancer," "has no effect on the risk of cancer," "increases risk of cancer," and "don't know."

Spectral shaper provides unprecedented control over 10,000 laser frequency comb lines
2025-10-30
WASHINGTON — Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than previously possible. This advance could provide an important new tool in the hunt for Earth-like planets outside our solar system.
When searching for exoplanets, astronomers use high-precision spectroscopy to detect tiny shifts in starlight that reveal a star’s subtle “wobble” due to an orbiting planet. But for Earth-sized planets, these wavelength changes are smaller than the spectrograph’s ...

Africa acacias ‘go for broke’ to grow, use up water to survive drought
2025-10-30
COLUMBUS, Ohio – Young umbrella acacia trees in Africa survive severe drought by putting their natural processes into overdrive when water is in short supply, prioritizing continued growth over water conservation, new research shows.
The study is the first genome-scale analysis of any African acacias and focuses on the umbrella acacia, an iconic feature of the African savanna.
Researchers compared the genetic response to drought stress of the umbrella acacia (Vachellia tortilis) and one of its hundreds of relatives, the splendid thorn acacia (Vachellia robusta) more commonly found in wetter regions of East Africa.
Results showed that ...

Sharing positive emotions with a partner is good for health
2025-10-30
Sharing happy moments with a partner may be good for older people’s health, lowering the level of the stress hormone cortisol in their bodies, according to research published by the American Psychological Association.
“We know from lots of research that positive emotions like happiness, joy, love and excitement are good for our health -- they’ve even been linked to living longer. But most of this research looks at people’s emotions as if they happen in isolation,” said study lead author Tomiko Yoneda, PhD, of the University of California Davis. “In real life, though, our most powerful positive emotions often happen when we’re connecting ...
Ergonomic insect headgear and abdominal buckle with surface stimulators manufactured via multimaterial 3D printing snap-and-secure installation of noninvasive sensory stimulators for cyborg insects
2025-10-30
Conventional approaches to cyborg insect preparation involve cutting antennae or cerci (sensory appendages) to implant electrodes, or using adhesives (like poly ionic liquid gels) to attach noninvasive films. “The methods have flaws: (1) Invasive implantation irreparably damages sensory organs, reducing the insect’s ability to detect obstacles and navigate; (2) Adhesive-based films degrade over time, cause exoskeleton harm during removal, and require skillful application—extending preparation time and limiting reuse; (3)Ethically, cutting appendages violates the “3Rs” framework (Replacement, Reduction, Refinement) for humane animal research, raising concerns about ...
