Alcohol and cancer videos

The alcohol industry (AI) is misrepresenting evidence about the alcohol-related risk of cancer with activities that have parallels with those of the tobacco industry, according to new research published in the journal Drug and Alcohol Review.

Led by the London School of Hygiene & Tropical Medicine with the Karolinska Institutet, Sweden, the team analysed the information relating to cancer which appears on the websites and documents of nearly 30 alcohol industry organisations around the world between September 2016 and December 2016. Most of the organisational websites (24/26) showed some sort of distortion or misrepresentation of the evidence about alcohol-related cancer risk, with breast and colorectal cancers being the most common focus of misrepresentation.

The most common approach involves presenting the relationship between alcohol and cancer as highly complex, with the implication or statement that there is no evidence of a consistent or independent link. Others include denying that any relationship exists or claiming inaccurately that there is no risk for light or ‘moderate’ drinking, as well discussing a wide range of real and potential risk factors, thus presenting alcohol as just one risk among many.

According to the study, the researchers say policymakers and public health bodies should reconsider their relationships to these alcohol industry bodies, as the industry is involved in developing alcohol policy in many countries, and disseminates health information to the public.

Alcohol consumption is a well-established risk factor for a range of cancers, including oral cavity, liver, breast and colorectal cancers, and accounts for about 4% of new cancer cases annually in the UK. There is limited evidence that alcohol consumption protects against some cancers, such as renal and ovary cancers, but in 2016 the UK’s Committee on Carcinogenicity concluded that the evidence is inconsistent, and the increased risk of other cancers as a result of drinking alcohol far outweighs any possible decreased risk.

This new study analysed the information which is disseminated by 27 AI-funded organisations, most commonly ‘social aspects and public relations organisations’ (SAPROs), and similar bodies. The researchers aimed to determine the extent to which the alcohol industry fully and accurately communicates the scientific evidence on alcohol and cancer to consumers. They analysed information on cancer and alcohol consumption disseminated by alcohol industry bodies and related organisations from English speaking countries, or where the information was available in English.

Through qualitative analysis of this information they identified three main industry strategies. Denying, or disputing any link with cancer, or selective omission of the relationship, Distortion: mentioning some risk of cancer, but misrepresenting or obfuscating the nature or size of that risk and Distraction: focussing discussion away from the independent effects of alcohol on common cancers.
