Better alcohol labelling – A way to boost awareness of the risk between alcohol and cancer?

In a guest blog, Ben Chiu, Policy Manager (Prevention & Health Services, Devolved) at Cancer Research UK explores the link between alcohol and cancer, and why we need to encourage governments to consider requiring alcohol products to contain information to help consumers understand what is in their drinks.

Most of us in the UK don’t know about the link between alcohol and cancer. It’s disappointing, but not exactly surprising. Our environment is so saturated by positive messages about alcohol that even the voices of medics and health bodies on its potential health risks get drowned out. 

It’s clear that something needs to change. There’s no silver bullet, but one way of increasing awareness would be requiring stronger, better labelling on alcohol products – potentially including cancer specific warnings.

Cancer itself is one of a number of serious health risk factors for drinkers. Everyone in the UK has a right to know about its link with alcohol. In 2018, Cancer Research UK published a study which found that drinking alcohol causes 11,900 cases of cancer each year in the UK. [i] Alcohol is linked with seven types of cancer. [ii][iii] There’s no safe level of drinking. The risk of oesophageal, oral cancers and breast cancer can increase even if you don’t drink much, while the risk of others increase if you drink a lot – such as bowel and liver cancer. [iv] [v][vi]

Although we know alcohol cause cancer, we don’t know exactly how.  There are a few different theories.. One is that your body turns alcohol into a toxic chemical that damages DNA. Another is that alcohol increases levels of some hormones. And the last is that alcohol makes it easier for other cancer-causing chemicals to absorbed into your body.

Boosting awareness of the link between alcohol and cancer has been challenging. Research shows over two thirds of people aren’t aware of cancer as a risk factor for drinking, and even when people have a list of health conditions in front of them, a third still can’t make the link.[vii] Of all social groups, younger people and those from poorer communities are the least likely associate the two.

This is why we need to get creative and encourage the UK and devolved governments to consider requiring alcohol products to contain information that empowers the public to know what they’re drinking. Better labelling could range from information on the 14 unit a week drinking guidelines, to specific warnings clearly stating the link between alcohol and cancer.

There is an array of encouraging evidence showing that better labelling could have a positive impact.

A review commissioned by Alcohol Focus Scotland found evidence that health warnings on alcohol products led to increased intention to reduce drinking, with further evidence that health warnings that link to a specific disease were especially effective.[viii] Similarly, a real-world experiment in Canada has shown that better alcohol labels (which included a cancer warning, the low-risk drinking guidelines and the standard drinks per serving) can increase people’s knowledge of the link between alcohol and cancer[ix] and the low-risk drinking guidelines,[x] and prompt people to cut back on their drinking.[xi] [xii]

It’s vital that more is done to ensure better awareness of the link between alcohol and cancer. Moving forward, Cancer Research UK encourages the UK and devolved governments and researchers to explore what better labelling could look like in the UK, with a view to providing consumers with the information they need and want to make informed choices.
