Cancer deaths overall have been falling for decades in the US, largely thanks to earlier detection and better treatment. A new study finds one exception to that encouraging trend: alcohol’s specific contribution to cancer mortality has been moving in the opposite direction, and even a single daily drink is enough to matter.
Key Takeaways
- A new analysis of over three decades of US data found the number of alcohol-attributable cancer deaths more than doubled between 1990 and 2023, rising from 11,361 to 23,126 per year.
- The increased risk applies to at least 10 cancer types: breast, prostate, colon, rectum, stomach, pancreatic, and liver cancers, plus cancers of the head and neck.
- Men and adults 55 and older saw the sharpest increases; the alcohol-related cancer mortality rate in older men climbed nearly 24% over the study period.
- Among adults 20 to 54, colorectal cancer overtook liver cancer as the leading alcohol-attributable cancer killer in men, and the second-leading cause in women.
What the Study Actually Found
Led by Dr. Chinmay Jani, chief clinical fellow in hematology and oncology at the University of Miami’s Sylvester Comprehensive Cancer Center, the study drew on more than 30 years of US data collected for the Global Burden of Disease study, a large-scale international effort tracking mortality and disability trends across more than 200 countries. The research, published in The Lancet Regional Health – Americas, found that even as cancer death rates overall have declined, the specific share of cancer deaths attributable to alcohol has moved in the other direction over the same period, alongside a more than twofold rise in the raw number of these deaths annually. “Overall, we know alcohol is closely related to liver cancer mortality,” Jani said, but the data showed a broader and, in some ways, more surprising pattern: among adults aged 20 to 54, colorectal cancer — not liver cancer — was the single leading cause of alcohol-attributable cancer death in men, and the second-leading cause in women.
Why Alcohol Affects Cancer Risk
According to the National Cancer Institute, alcohol contributes to cancer risk through several mechanisms: it breaks down into acetaldehyde, a compound that can damage DNA; it can raise estrogen levels, relevant specifically to breast cancer risk; and it interferes with the body’s ability to absorb key nutrients thought to help protect against cancer, including vitamins A, C, D, and E, along with B-complex folates. Notably, the researchers found that even a single standard drink a day was associated with a measurably higher alcohol-related cancer risk — this wasn’t a pattern that only appeared at heavy drinking levels. The study didn’t find one type of alcoholic beverage to be riskier than another; a standard drink in the US is defined as 12 ounces of regular beer, 5 ounces of wine, or 1.5 ounces of 80-proof liquor, and the increased risk applied to alcohol generally rather than any specific beverage category.
This research also arrives at a moment of shifting federal guidance. For decades, US dietary guidelines recommended capping alcohol intake at two drinks a day for men and one for women. In January 2026, the Trump administration removed those specific numerical limits, replacing them with broader language simply advising people to “consume less alcohol for better overall health” — a change that makes independent research like this study more relevant to how people interpret their own risk, absent a specific federal benchmark.
Who’s Being Affected Most
The demographic pattern in this data is worth understanding on its own. Men and adults 55 and older experienced the largest increases in alcohol-related cancer mortality, with rates in older me
