For years, a glass of wine with dinner has carried a reputation as a harmless, even heart-healthy, habit. A major new analysis from researchers at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, adds real weight to a message public health researchers have been repeating with growing urgency: when it comes to cancer risk, there’s no amount of alcohol that’s been shown to be truly safe.
Here’s what the study actually found, what the numbers really mean once you look past the headline, and what the evidence supports for anyone thinking about their own relationship with alcohol.

What the Study Actually Found
The research, led by Dr. Chinmay Jani, chief fellow in hematology and oncology at Sylvester, analyzed more than three decades of Global Burden of Disease data. It was first presented at the 2025 American Society of Clinical Oncology Annual Meeting, where Jani received the Conquer Cancer Merit Award for the work, and has since been published in The Lancet Regional Health – Americas.
The topline number: annual alcohol-attributable cancer deaths in the United States rose from 11,361 in 1990 to 23,126 in 2023, roughly doubling over 33 years. The researchers found this isn’t just a liver cancer story either. Alcohol is now linked to at least 10 tumor types, including breast, colorectal, esophageal, pancreatic, and mouth and throat cancers, in addition to liver cancer.
Dr. Jani summarized the core message plainly: alcohol is a real, established risk factor for cancer, capable of acting as a carcinogen across multiple different cancer types, a fact worth knowing regardless of whether someone drinks daily or only occasionally.
One specific finding from the study stands out for younger and middle-aged adults in particular: among adults aged 20 to 54, colorectal cancer, not liver cancer, was the leading cause of alcohol-attributable cancer mortality in men, and the second leading cause in women, behind only breast cancer. As Dr. Jani put it, that finding surpasses what most people would assume, since the public generally associates alcohol most strongly with liver disease. Asked how much alcohol was enough to raise risk, Jani told CNN it didn’t take much: roughly one standard drink a day, every day, was associated with increased risk, where a standard U.S. drink is defined as 12 ounces of regular beer, 5 ounces of wine, or 1.5 ounces of 80-proof liquor.
The Nuance Behind the Headline Number
Here’s where an honest breakdown matters, because the raw doubling of deaths, while real and worth taking seriously, tells only part of the story. A meaningful share of that increase reflects the simple fact that the U.S. population has grown and aged substantially since 1990, not that any individual person’s risk from a given amount of alcohol has doubled.
When researchers adjusted for population growth and aging, using what’s called an age-standardized mortality rate, the picture looked more modest: the rate rose from 3.8 to 4.1 deaths per 100,000 people, a 7.6 percent increase. What did rise more sharply was alcohol’s proportional share of all cancer deaths, climbing from about 2.2 percent in 1990 to 3.5 percent in 2023, a 58.5 percent relative increase, even as overall U.S. cancer mortality has been declining for decades thanks to better screening, reduced smoking rates, and improved treatment. In other words, cancer overall is killing fewer Americans than it used to, but alcohol is responsible for a growing share of the cancer deaths that do still occur.
It’s also worth being precise about who’s most affected. According to the study, adults aged 55 and older accounted for 19,460 of the 23,126 total alcohol-attributable cancer deaths in 2023, roughly 84 percent of the total, and this age group experienced roughly eight times the alcohol-attributable cancer death rate of adults aged 20 to 54. That doesn’t mean younger and middle-aged drinkers are unaffected, colorectal cancer in particular has been a growing concern among younger adults in cancer research more broadly, but it does mean the “moderate glass of wine” demographic isn’t uniformly at the same elevated risk level as older, longer-term drinkers, and headlines that flatten that distinction can overstate the risk for some readers while understating it for others.
Why There’s No Established “Safe” Amount
Despite that nuance, the core public health message from this research and the broader body of alcohol-cancer research remains genuinely important: no amount of alcohol consumption has been established as safe from a cancer risk standpoint. Alcohol has been classified as a carcinogen by international health authorities since 1987, and the mechanism is well understood at this point. When your body processes alcohol, the liver breaks ethanol down into acetaldehyde, a compound the National Cancer Institute classifies as a toxic chemical and probable human carcinogen capable of directly damaging DNA. That’s one of several biological pathways researchers have identified linking alcohol to increased cancer risk, alongside effects on hormone levels tied to breast cancer risk and alcohol’s role as a solvent that can increase absorption of other carcinogens, notably in cancers of the mouth and throat.
This finding isn’t unique to the Sylvester study either. A 2025 U.S. Surgeon General’s advisory on alcohol and cancer risk reached similar conclusions, and separate research published in BMC Public Health has found that a substantial share of total alcohol-attributable cancer deaths and disease burden trace back to moderate drinking specifically, not just heavy drinking, precisely because far more people drink moderately than drink heavily, meaning the cumulative population-level impact of moderate drinking is larger than intuition might suggest, even though any individual moderate drinker’s personal risk elevation is smaller than a heavy drinker’s.
Which Cancers Are Most Affected
Among the specific cancer types studied, liver cancer accounted for the largest number of alcohol-attributable deaths in 2023, at 7,686, and also showed the steepest rate of increase over the study period. Esophageal cancer followed at 4,902 deaths, and colorectal cancer at 3,818. Breast cancer, pancreatic cancer, and cancers of the mouth and throat rounded out the remaining significant contributors identified in the research.
Why Public Awareness Has Lagged So Far Behind the Science
One of the more striking aspects of this research isn’t the data itself, it’s the gap between what’s been scientifically established and what most people actually know. Alcohol has carried an official cancer-causing classification from international health authorities since 1987, nearly four decades ago. Yet surveys consistently find that a majority of American adults are unaware of alcohol’s link to cancer at all, let alone aware that the link extends across ten or more distinct cancer types rather than being confined to liver disease, the association most people do vaguely associate with heavy drinking.
Part of this gap likely traces back to decades of conflicting messaging around alcohol and health more broadly, including widely publicized research from the 1990s and 2000s suggesting moderate drinking, particularly red wine, might offer cardiovascular benefits. More recent, methodologically stronger research has substantially undercut those earlier findings, with many researchers now arguing that the apparent heart-health benefit of moderate drinking in older studies was likely explained by confounding factors, such as moderate drinkers tending to have other health-conscious habits, rather than alcohol itself providing genuine protective benefit. That evolving scientific consensus hasn’t fully caught up with public perception yet, which is part of why research like this new analysis matters for closing that awareness gap directly.
Where This Leaves You
If you drink alcohol regularly, even in amounts generally considered “moderate,” this research is a legitimate reason to think honestly about that habit, without needing to treat it as a reason for panic over an occasional drink. A few things worth considering:
- Understand that “moderate” was never the same as “risk-free.” The phrase describes a lower relative risk compared to heavy drinking, not the absence of risk entirely.
- Know your own family history and risk factors. If you have a family history of breast, colorectal, or liver cancer specifically, alcohol’s contribution to your personal risk profile is worth discussing directly with your doctor.
- Consider tracking your actual weekly intake, since it’s easy to underestimate how much you drink when it’s spread across a week of dinners, social events, and casual drinks rather than counted deliberately.
- Reducing intake, even without fully eliminating it, appears to lower risk. Research cited in this broader body of evidence has found that shifting from moderate to light drinking prevents a meaningfully larger share of alcohol-attributable cancer deaths than shifting from heavy to moderate drinking does, suggesting real benefit exists at every level of reduction, not just at abstinence.
- Stay current on cancer screening appropriate for your age, particularly colorectal cancer screening, given both alcohol’s role and the broader trend of rising colorectal cancer rates among younger and middle-aged adults independent of alcohol specifically.
- Talk to your doctor before making major changes if you drink heavily or daily, since abruptly stopping heavy, regular alcohol use can carry its own medical risks and may require supervised support.
Supporting Your Body If You’re Cutting Back
For those looking to reduce alcohol intake, whether cutting back gradually or eliminating it, supporting your body through the transition and beyond can help make the change more sustainable.
Vinia offers a supplement specifically designed to support the body’s response before and after alcohol consumption, which some people find useful during a gradual reduction process rather than an abrupt stop. Discount is built into the link at checkout.
For general liver and antioxidant support during a period of reduced alcohol intake, Codeage offers clean-label supplements, including liver-support formulas, for those looking to support their body’s natural detoxification processes. Use code HEALTHYWILDFREE10 at checkout.
To be clear, neither of these products reverses existing alcohol-related health effects or eliminates cancer risk associated with alcohol consumption. The clearest, most evidence-supported way to reduce alcohol-related cancer risk is reducing or eliminating alcohol intake itself, not offsetting it with a supplement.
The Bottom Line
Alcohol-attributable cancer deaths in the U.S. have genuinely doubled in raw numbers since 1990, and alcohol’s share of all cancer deaths has risen sharply even as cancer mortality overall has declined. Much of that raw increase reflects a larger, older population rather than a doubling of personal risk, and the sharpest impact remains concentrated among older adults, not the occasional moderate drinker in their 30s or 40s. Still, the underlying scientific conclusion holds up under scrutiny: no amount of alcohol has been established as free of cancer risk, and reducing intake, at any level, appears to meaningfully reduce that risk. That’s a more honest, more useful takeaway than either “one glass of wine is destroying your health” or “moderate drinking has nothing to worry about,” and it’s the version of this story your own health decisions deserve. As awareness research continues to close the decades-long gap between what scientists have understood and what the public has been told, expect this to remain an active, evolving conversation, one worth revisiting periodically as new research refines exactly how much risk different levels of drinking actually carry.
