In a groundbreaking new report, U.S. Surgeon General Vivek Murthy is calling attention to the established connection between alcohol consumption and an increased risk of seven types of cancer. With alcohol being a known carcinogen, this report urges both heightened public awareness and the implementation of cancer warning labels on alcoholic beverages.
The relationship between alcohol and cancer has long been recognized in the medical community. Despite the mounting scientific evidence, many Americans are still unaware of the risks. Dr. Bruce Scott, president of the American Medical Association (AMA), has emphasized that alcohol consumption, regardless of the amount, remains a significant modifiable risk factor for several cancers. The AMA has long advocated for clearer messaging on alcohol’s cancer risks, which the Surgeon General’s report now echoes.
The seven cancers linked to alcohol use include cancers of the mouth, throat, larynx, liver, breast, esophagus, and colon. This sobering reminder comes as a wake-up call for many Americans, who may be unaware of the severe health implications of even moderate drinking.
The World Health Organization (WHO) has concluded that there is no safe level of alcohol consumption when it comes to cancer risk. Alcohol can damage cellular DNA, disrupt hormone levels, and increase the body’s absorption of carcinogens such as tobacco smoke, making individuals more vulnerable to certain cancers.
While the health risks from drinking increase with the amount consumed, even small quantities pose some level of risk. Research has shown that women who consume less than one drink a week have a 17% risk of developing an alcohol-related cancer in their lifetime. For those who consume two drinks daily, that risk jumps to 22%. Men face similar risks, with a 10% lifetime risk for moderate drinkers and 13% for heavier drinkers.
Alcohol is the third leading preventable cause of cancer in the U.S., trailing only tobacco and obesity. According to the Surgeon General’s report, alcohol is responsible for approximately 100,000 cancer cases and 20,000 cancer-related deaths annually. The WHO classifies alcohol as a “Group 1” carcinogen, placing it in the same category as tobacco, asbestos, and radiation—substances known to cause cancer in humans.
While the risks associated with alcohol consumption are serious, doctors note that it’s never too late to reduce your cancer risk. However, the timeline for reversing the damage may be longer than people expect. Studies suggest that it could take decades for the cancer risk of those who have quit drinking to return to that of someone who has never consumed alcohol.
Dr. Rotonya Carr, a gastroenterology expert at the University of Washington, explained that while health improvements such as better blood pressure and weight loss can be seen after just a month of sobriety, cancer risks remain elevated for years, particularly for those who have engaged in heavy drinking over extended periods.
Current U.S. dietary guidelines recommend no more than one drink per day for women and two for men. However, new evidence suggests that even drinking within these limits may increase the risk of developing cancer, as well as heart disease and other health problems. With these guidelines likely under review, changes may be on the horizon to better reflect the growing evidence on alcohol’s risks.
Other countries, such as Canada, have already taken a more cautious stance, advising that no level of alcohol is safe.
Some studies have suggested potential health benefits from moderate alcohol consumption, particularly red wine, which contains antioxidants believed to be heart-healthy. However, many health experts remain skeptical. Dr. William Dahut of the American Cancer Society stated that any potential benefits are overshadowed by the substantial cancer risks associated with alcohol.
“There may have been some enthusiasm about the benefits of red wine years ago, but much of that has proven difficult to validate,” said Dr. Dahut.
While some people believe that certain types of alcohol—like wine or beer—are less harmful than others, the truth is that the risk comes from the alcohol itself, not the beverage. Experts warn that drinks with hidden alcohol content, such as spiked seltzers and pre-mixed teas, can easily lead to overconsumption without people realizing it.
The Surgeon General’s advisory aims to provide a clear, well-informed message about the risks of alcohol consumption. While the effects of alcohol on cancer risk may not be immediately visible, the damage done at the cellular level is real, and its consequences can be severe. Experts hope that this new information will prompt individuals to reconsider their drinking habits and make informed choices for their health.
As younger generations drink less, possibly due to increased awareness of risks or the availability of alternatives like vaping, older adults have seen an uptick in alcohol consumption. The Surgeon General’s report underscores the importance of continuing to educate the public about the long-term health risks of drinking.
Dr. Paul Gilbert, an associate professor at the University of Iowa, highlights that while the Surgeon General’s warning might not cause an immediate change in habits, it is a step toward better public health awareness. Dr. Elizabeth Kovacs, a surgery professor at the University of Colorado, noted that many people under 35 are already drinking less, but older age groups need more attention.
The hope is that this increased awareness will lead to healthier choices and a reduction in alcohol-related health problems moving forward.
