Researchers analyzing more than three decades of U.S. health data have found that the share of cancer deaths attributable to alcohol has doubled among adults aged 20 and older. The findings, published in The Lancet Regional Health – Americas, highlight a growing public‑health burden linked to even modest drinking levels.
Scope of the increase
The study examined data from the Global Burden of Disease project spanning 1990 to 2023. During that period, annual deaths tied to alcohol‑related cancers rose from 11,361 to 23,126, more than a two‑fold increase. While overall cancer mortality in the United States has declined, the proportion of deaths linked to alcohol has risen sharply, according to Dr. Chinmay Jani, the study’s first author and chief clinical fellow in hematology and oncology at the University of Miami’s Sylvester Comprehensive Cancer Center.
Jani noted that the heightened risk applies to a range of cancers, including breast, prostate, colon, rectum, stomach, pancreas, liver, and cancers of the head and neck. Among adults aged 20 to 54, colorectal cancer was the leading alcohol‑attributable cause of death for men and the second‑leading cause for women, overtaking liver cancer in both groups. For women of the same age bracket, alcohol‑related breast cancer topped the list.
Risk at low consumption levels
The researchers emphasized that the increased risk emerges at relatively low consumption. In the United States, a standard drink equals 12 ounces of regular beer, 5 ounces of wine, or 1.5 ounces of 80‑proof distilled spirits. The study suggests that even one standard drink per day, consumed daily, can raise the likelihood of cancer mortality.
Federal guidelines have long recommended a maximum of two drinks per day for men and one for women. In January, those limits were removed by the Trump administration, which instead advised the public to “consume less alcohol for better overall health.” Cardiologist Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health, said the new evidence underscores that “there is no safe amount of alcohol consumption.”
Biological pathways and demographic differences
According to the National Cancer Institute, alcohol influences cancer risk through several mechanisms. Ethanol is metabolized in the liver to acetaldehyde, a probable human carcinogen that can damage DNA and impede repair processes. Alcohol also induces oxidative stress, inflammation, and weakens the mucosal lining of the mouth and throat, making tissues more vulnerable to carcinogens, especially when combined with smoking.
Additionally, alcohol interferes with the absorption of nutrients thought to protect against cancer, such as vitamins A, C, D, E, and folate. The study found that older men (55 and above) experienced the greatest rise in alcohol‑related cancer mortality, with a nearly 24 % increase over the 33‑year period. For older men, liver cancer showed the strongest link, followed by esophageal and colorectal cancers. Among women 55 and older, breast cancer was the top alcohol‑related killer, followed by liver and colorectal cancers.
Jani explained that younger adults and women appear to be at higher relative risk per unit of alcohol consumed. “If the same proportion of alcohol is taken by a female or by a younger male or female, it’s considered a much higher risk potential for cancer development,” he said.
Even cancers with the smallest observed increases—prostate, pancreatic, and stomach—showed upward trends over time. Head and neck cancers, which include malignancies of the lip, oral cavity, pharynx, larynx, and esophagus, were linked to alcohol in up to one‑quarter of cases, suggesting a sizable prevention opportunity.
While the study does not claim that complete abstinence is required, the authors conclude that reducing alcohol intake to the lowest possible level is the most prudent strategy for minimizing cancer risk.
