Public health warnings about the link between alcohol consumption and cancer may be more effective when they name specific types of cancer and include visual representations of potential health consequences, according to a new study published in the journal Cancer.
Alcohol is classified as a carcinogen and has been linked to several types of cancer, including breast, colorectal, liver, oral, throat, laryngeal and esophageal cancers. Despite this established connection, many people remain unaware that drinking alcohol can increase their cancer risk.
“Many people remain unaware that alcohol is linked to several cancers,” said Dr. Taghrid Asfar, a professor of public health sciences at the University of Miami and the study’s lead researcher.
The study involved 639 U.S. adults aged 21 and older who consumed alcohol. Participants were shown different messages about the relationship between alcohol and cancer and were then asked to evaluate how they responded to the information.
The results showed that participants were more likely to consider warnings informative, credible and attention-grabbing when they identified specific types of cancer associated with alcohol use. The effect was particularly strong when the messages were accompanied by visual content, including AI-generated images illustrating potential health consequences.
The researchers also found that moderate drinkers were generally more responsive to the warnings than heavy drinkers, who were less likely to engage with the messages.
However, the study did not determine whether exposure to the warnings actually changed participants’ drinking habits over the long term.
The researchers say that effective cancer-prevention communication needs to take into account people’s readiness to change their behavior as well as their understanding of health risks.
“Effective cancer prevention communication must be tailored to where people are psychologically — their readiness to adopt behavioral changes and their understanding of the relative risks involved,” said Frank Penedo, director of the Sylvester Survivorship and Supportive Care Institute at the University of Miami.
He added that testing different approaches to health communication can help researchers determine which messages attract attention, build trust and encourage people to make informed decisions about their health.
Further research is needed to determine whether more effective warnings can not only improve people’s understanding of the relationship between alcohol and cancer but also lead to reductions in alcohol consumption.
“Our goal is not simply to tell people that alcohol can increase cancer risk, but to understand how to communicate that information in ways people notice, trust and remember,” Asfar said.
The researchers hope their findings will contribute to clearer, evidence-based public health campaigns that can help people better understand the cancer risks associated with alcohol and make informed decisions about drinking.
