Alcohol is estimated to have caused more than 741,000 cancer cases last year, with the majority of cases involving cancers of the oesophagus, liver and breast.

Existing evidence strongly suggests that alcohol consumption can cause various cancers, though the researchers involved in this study believe the links are ‘often unknown or overlooked.’

To indicate exactly how many cancer cases alcohol can cause globally, the team used data such as existing alcohol consumption estimates for 2010 and risk estimates for cancers known to be linked to alcohol and combined the figures with existing estimates of new cancer cases expected for 2020.

The researchers used estimates of cancer cases to avoid disruptions caused by the coronavirus pandemic, and noted the importance of a ‘latency period between the year of alcohol exposure data and the year of cancer diagnosis’, with co-author Harriet Rumgay explaining there is a ‘delay between alcohol consumption and possible cancer development.’

Through the data, the researchers estimate that alcohol consumption was responsible for 568,700 cancer cases in men and 172,600 cases in women in 2020.

Though the majority of estimated cancer cases in the study involved cancers of the oesophagus, liver and breast, the proportion of cases deemed to be caused by alcohol was highest for cancers of the oesophagus, pharynx, and lip and oral cavity when looking at the causes of each cancer type separately, The Guardian reports.

Most alcohol-caused cancer cases were linked to heavy drinking, though the data indicated that drinking up to 10g of alcohol a day, which equals a half pint or small glass of wine, contributed to between 35,400 and 145,800 cases globally in 2020.

In the wake of the findings, Rumgay said members of the public need to become more aware of the link between alcohol and cancer, and that policies need to be introduced to decrease overall alcohol consumption and reduce the ‘burden of cancers’, as well as other alcohol-related diseases.
