A Canadian study has found that drinking a pint of beer daily significantly elevates the risk of being diagnosed with pancreatic cancer. The research suggests that consuming the equivalent of 21 units of alcohol per week, which is the average intake for Britons, increases the chance of developing the disease by 10 to 30 percent.
Currently, alcohol consumption is not officially listed as a risk factor for pancreatic cancer by major health organizations. However, Dr. Tim Naimi, one of the study's authors, stated that a growing body of evidence supports alcohol's role in the disease's development. The World Health Organization already links alcohol consumption to seven other types of cancer, including mouth and breast cancer.
The National Health Service (NHS) advises adults to limit their alcohol intake to no more than 14 units per week, which is approximately one medium glass of wine or a pint of standard beer per night. Despite this recommendation, research indicates that a majority of Britons exceed this limit.
Pancreatic cancer is considered one of the deadliest forms of cancer, partly due to subtle early symptoms that often go unnoticed. In the UK, it results in approximately 10,000 deaths annually, equating to one death per hour. Survival rates are stark, with nine in ten patients dying within a year of diagnosis. While it can affect individuals of any age, it is most frequently diagnosed in those over 80.
Like many cancers, the risk of pancreatic cancer increases with age. Other known risk factors include smoking and obesity. Worryingly, the incidence of pancreatic cancer has been rising, with Cancer Research UK reporting an 18 percent increase in prevalence since the early 1990s. Projections suggest it may soon overtake breast cancer as the fourth leading cause of cancer-related death in the UK.
Experts involved in the study hope these findings will inform the public about the risks associated with alcohol consumption and potentially help reduce the number of new cases. Dr. Naimi and his team at the Canadian Institute for Substance Use Research at the University of Victoria believe it is time to officially recognize pancreatic cancer as an alcohol-related disease.
