Alcohol-linked cancer deaths have doubled, study reveals… and the death toll is far beyond the liver
Deaths from multiple cancers linked to alcohol have surged in the past several decades, new research shows.
Experts believe when the body breaks down alcohol, it creates a toxic chemical called acetaldehyde that destroys healthy cells and results in a prime environment for cancer cells to thrive.
As a result, alcohol is considered a Group 1 carcinogen, meaning there is sufficient proof that the drink causes cancer.
Recent evidence has increasingly sounded the alarm on alcohol’s potential link to colon, liver and stomach cancers, especially as these diseases soar in young Americans.
Now, Florida researchers have urgently warned that alcohol-related cancer deaths are on the rise throughout the US.

Using 33 years’ worth of health data from thousands of Americans, the team found alcohol-attributable cancer deaths in the US doubled from about 11,400 in 1990 to 23,100 in 2023.
And among adults under 55, colon and breast cancers were the leading alcohol-related cancer deaths, with esophageal, prostate and pancreatic cancers also seeing unprecedented growth.
The researchers believe the findings show alcohol is becoming one of the most prominent modifiable risk factors in reducing cancer rates, particularly in younger Americans.

‘The most surprising finding was the breadth of alcohol’s potential impact across cancer types,’ Dr Chinmay Jani, corresponding study author and chief fellow in hematology and oncology at the Sylvester Comprehensive Cancer Center in Miami, said.
‘Although its relationship with liver cancer is widely recognized, its contribution to cancers such as colorectal, esophageal, breast, pancreatic and prostate cancer is less well understood by the public.’
The current Dietary Guidelines for Americans urges adults to ‘consume less alcohol for better overall health.’ Previous guidelines suggested men have less than two drinks per day while women have one.
The new study, published in The Lancet Regional Health – Americas, looked at cancer death rates and alcohol-related cancer death rates between 1990 and 2023 for 10 different forms of cancer: esophageal, stomach, liver, larynx, breast, prostate, colorectal, lip and oral cavity, pharynx and pancreatic.
The researchers used statistical modeling to calculate which deaths were related to alcohol-consumption.
Overall, alcohol-attributable cancers increased from 11,361 in 1990 to 23,126 in 2023, a 103 percent rise. Men and adults over 55 saw the highest concentrations of deaths, and the leading cause of alcohol-related death was liver cancer, followed by esophageal and colorectal cancers.

There were also increases in alcohol-related deaths from all cancers studied except liver cancer. The greatest increase (57 percent) was in stomach cancer, followed by 40.5 percent for pancreatic cancer and 39.7 percent for colorectal cancer.
In men ages 20 to 54, colorectal cancer was the leading cause of alcohol-related death, followed by esophageal cancer. For women in the same age group, the leading cause was breast cancer, followed by colorectal cancer.
Alcohol-related deaths from liver cancer showed the largest increase in men (88.6 percent) and women (147.8 percent), followed by colorectal cancer for men (30.2 percent) and pancreatic cancer for women (35.6 percent).
‘Notably, among adults aged 20 to 54, colorectal cancer was the leading cause of alcohol-attributable cancer mortality in men and the second leading cause in women, surpassing liver cancer in both groups,’ Jani said.
The study also looked at state-by-state alcohol-related cancer death data and found that in 2023, Washington DC had the highest rate for both sexes, followed by Texas for men and Alaska for women.
Utah, meanwhile, had the lowest rate for both sexes, which may be due to the state consistently recording the country’s lowest alcohol consumption rate. Washington DC, meanwhile, has some of the nation’s highest wine consumption and binge drinking rates, primarily fueled by young professionals.
‘What this study makes clear is that alcohol-related cancer risk is not limited to one disease or one group of people,’ Dr Gilberto Lopes, senior study author and chief of the Division of Medical Oncology at the Sylvester Comprehensive Cancer Center, said.
‘As physicians and cancer researchers, we have an opportunity to help patients understand that alcohol is a modifiable risk factor and that even small, informed changes can be part of a broader strategy to reduce cancer risk in our community.’
The researchers stressed the importance of raising awareness of alcohol’s relationship to cancer, especially for forms of the disease beyond liver cancer.
‘The most important takeaway is greater awareness that alcohol may affect cancer risk beyond the liver,’ Jani said.
‘These findings highlight alcohol as a potentially modifiable risk factor, and while the lowest safe dose is not yet known, this study suggests that reducing consumption to the lowest amount feasible for each individual may help lessen its impact on cancer risk and overall health.’
