Alcohol-Attributable Cancer Mortality Rose by Nearly 8% as Overall US Cancer Deaths Fell
Between 1990 and 2023, alcohol-attributable cancer deaths in the United States more than doubled, climbing from 11,361 to 23,126, according to an observational trend analysis published in The Lancet Regional Health – Americas. While overall US cancer mortality declined over the same three-decade span due to better prevention, screening, and treatment, the age-standardized alcohol-attributable cancer mortality rate increased by 7.9%, moving from 3.8 to 4.1 deaths per 100,000 population.
“Our study adds a long-term, population-level perspective on how alcohol-attributable cancer mortality has changed in the United States over more than three decades,” said lead author Chinmay Jani, MD, a medical oncologist at Sylvester Comprehensive Cancer Center at the University of Miami. Jani noted that one of the most striking findings was the divergence between overall falling cancer rates and the stubborn rise in alcohol-linked deaths.
Demographic Shifts in Alcohol-Related Cancer Deaths Among Men and Women
The burden of alcohol-related cancer mortality shifted unevenly across sex and age groups between 1990 and 2023. According to the data, alcohol-attributable mortality rates increased by 14.3% among men, while falling 16% among women. Concurrently, alcohol’s share of all cancer mortality rose 92% among men and 16.7% among women.
Age played a major role in the trajectory of these figures. Adults aged 55 and older saw a 21.5% increase in their alcohol-attributable cancer mortality rate. For younger adults aged 20 to 54, the rate remained essentially unchanged. Among younger men, overall cancer mortality dropped 34%, yet the alcohol-attributable portion still climbed 14%.

Liver Cancer Leads Increase Across US States and Tumor Types
Liver cancer registered the largest increase among the studied malignancies, with its alcohol-attributable mortality rate surging 114% from 0.6 to 1.3 deaths per 100,000 population between 1990 and 2023. By the end of the study period, liver cancer accounted for the highest number of alcohol-attributable cancer deaths, followed by esophageal cancer at 0.9 deaths per 100,000 and colorectal cancer at 0.7.
Geographic disparities were also pronounced. Washington, DC, recorded the highest alcohol-attributable cancer mortality rates in 2023, while Utah recorded the lowest. Rates increased among men across 47 states and among women in 17 states, with particularly sharp rises for men in Oklahoma, New Mexico, West Virginia, and Tennessee.
Methodological Considerations and Confounding Factors in Cancer Models
Independent experts emphasize that the findings reflect modeled population estimates rather than direct measurements. Jason Oke, DPhil, of the Centre for Evidence-Based Medicine at the University of Oxford, who was not involved in the research, cautioned that the analysis relies on approximations and modeled exposure data. Residual confounding from related risk factors like smoking and obesity remains difficult to disentangle from alcohol’s direct effects.
“Someone diagnosed with cancer in 2015 may have developed their cancer partly because of alcohol consumption 20 or more years earlier,” Oke said, pointing out that the analysis does not account for the long latency period between alcohol exposure and cancer death.
Investigators also acknowledged that the Global Burden of Disease database relied upon lacked granular patient-level data regarding race, ethnicity, and social determinants of health.
Frequently Asked Questions About Alcohol Consumption and Cancer Risk
Which cancers are most strongly linked to alcohol exposure?
Alcohol has established causal links to several malignancies, including breast, colorectum, liver, esophagus, and upper aerodigestive tract cancers.
How does alcohol interact with other lifestyle risk factors?
Alcohol can act synergistically with smoking and obesity to increase overall cancer risk. Researchers note that separating the independent effects of alcohol from tobacco use and metabolic health remains a complex challenge in population studies.
What did researchers identify as the primary takeaway for public health?
Chinmay Jani stated that the study’s key contribution is identifying where the alcohol-attributable burden is growing so populations can benefit from targeted prevention, and reinforcing that cancer prevention discussions should include alcohol alongside tobacco and other risk factors.
