Nearly 6 in 10 U.S. adults now recognize that regular alcohol consumption increases cancer risk, according to an October 2026 survey by the Annenberg Public Policy Center. Health leaders during Breast Cancer Awareness Month emphasize that alcohol remains a modifiable risk factor linked to at least seven types of cancer, particularly breast cancer.
Data from the Annenberg Science and Public Health survey conducted between September 22 and October 5, 2026, revealed that 58 percent of U.S. adults know about the connection between alcohol and cancer. This figure marks a five-percentage-point increase since February 2026 and stands 18 percentage points higher than when the survey first tracked the question in September 2024. The survey team includes Kathleen Hall Jamieson, the policy center’s director emerita, along with Gibson, Ken Winneg as managing director of survey research, Patrick E., research analyst Shawn Patterson Jr., and Jamieson as director of the Annenberg Health and Risk Communication Institute.
More than four in ten Americans do not recognize the risk. Specifically, 24 percent of adults report being unsure whether alcohol affects cancer development, while 17 percent incorrectly believe that drinking has no effect on cancer risk. The survey by the Annenberg Public Policy Center at the University of Pennsylvania was conducted among 1,842 empaneled U.S. adults by SSRS, an independent research company, with a margin of error of plus or minus 3.2 percentage points.
How Alcohol Consumption Impacts Breast Cancer Risk
Medical experts emphasize that ethanol breaks down in the body into acetaldehyde, a toxic chemical capable of damaging DNA. Additional risks stem from oxidative stress and altered levels of estrogen and other hormones associated with the disease.
Alcohol consumption elevates circulating estrogen levels by stimulating aromatase, an enzyme that results in high levels of estrogen in the blood. According to Dr. Charles Smith, an addictionologist with Recovery First Treatment Center, alcohol consumption is the third leading preventable cause of cancer in the United States, trailing tobacco and obesity.
what it drills down to is that drinking about one glass of wine a day, or one standard drink, increases risk of breast cancer over the long term by about 10 percent.

Data compiled across multiple studies indicates that women consuming one standard drink per day experience a 7 to 10 percent increase in breast cancer risk compared to non-drinkers, while women consuming fewer than 1 drink per day face a 5 percent increase. For those consuming two to three drinks daily, the risk rises by about 20 percent, climbing further to 32 percent for individuals consuming three to four drinks per day.
Guidance From Health Agencies and Medical Leaders
The World Health Organization issued a statement concluding there is no safe amount of alcohol, while the American Cancer Society updated its guidance from recommending moderation to suggesting it is best not to drink. Furthermore, the U.S. Surgeon General recently issued an Alcohol and Cancer Risk Advisory and pushed for warning labels on alcoholic beverages, following an earlier advisory from surgeon general Dr. Vivek Murthy.
Tonja Winekauf, a nurse practitioner with UnityPoint Health, noted that alcohol alters hormone levels, increases inflammation, and enhances the absorption of harmful substances. Winekauf advises that most women start regular screenings at age 40, though those with a family history of cancer should talk to their doctor about screening earlier.
The important thing is to understand that alcohol is one ofseveral factors that can affect breast cancer risk, and reducing your intake is one practical step you can take.

For healthy women who choose to drink, it is generally advised to limit consumption to reduce risk. Alongside limiting alcohol, clinicians recommend maintaining a balanced diet, quitting smoking, and increasing physical activity to help mitigate overall breast cancer risk. Readers seeking personalized guidance on screening schedules, risk reduction, or alcohol consumption should consult a qualified healthcare professional.
Tonja Winekauf noted that one in 8 women will be diagnosed with breast cancer in her lifetime.
