Moving beyond the "Health Halo" of Alcohol: What Will it Take to Achieve Population Awareness of the Cancer Risks of Alcohol?

We discuss the implications of Seidenberg and colleagues' report confirming low levels of accurate awareness of the cancer harms associated with alcohol use, including wine, beer, and liquor consumption. The authors propose that academic and lay messaging describing consumption of wine and other forms of alcohol as reducing heart disease risk has created generalized beliefs about the health benefits of drinking alcohol. This "health halo" surrounding alcohol consumption leads the public to overgeneralize alcohol health benefits to other diseases, including cancer. We discuss the need to address high levels of perceived risk uncertainty to help the public distinguish between the impact of alcohol on heart disease versus cancer, and to overcome other barriers to including alcohol use reduction as a cancer prevention strategy. Given recent increases in U.S. population drinking rates, as well as morbidity and mortality associated with alcohol use, the time is right to marshal multilevel efforts to educate the public regarding the fact that alcohol is carcinogenic. If successful, these efforts will have multiple downstream benefits, including the ability of the lay public to use the most up-to-date scientific evidence to make informed decisions about whether, and how much, to engage in a risky behavior.
