Alcohol Linked to Seven Cancer Types
Following recommendations from surgeons earlier this year, which highlighted the relationship between alcohol and seven cancer types, a recent study by the International Agency for Research on Cancer (IARC) has uncovered another significant risk associated with alcohol consumption.
This study, published in the Journal Plos Medicine, categorizes alcohol as a carcinogen and underscores the increased risk for pancreatic cancer.
Previous warnings from the Surgeon General included breast cancer (in women), along with risks for large intestine, esophagus, voice box, liver, mouth, and throat cancers.
Interestingly, researchers found that the risk of pancreatic cancer is linked to beer and liquor, but not to wine.
Dr. Pietro Ferrari, who leads nutrition and metabolism research at IARC, stated, “While alcohol consumption is recognized as a carcinogen, prior evidence specifically connecting it to pancreatic cancer has not been deemed conclusive.”
The current findings suggest that pancreatic cancer should be added to the list of cancers associated with alcohol consumption, which some experts think has been overlooked until now.
For the study, about 2.5 million participants averaged around 57 years of age and were monitored for roughly 16 years. During this period, there were 10,067 cases of pancreatic cancer.
The research indicated that for every 10 grams of alcohol consumed daily, the risk of pancreatic cancer increased by 3%.
Women consuming 15-30 grams of alcohol daily (equivalent to 1-2 standard drinks) had a 12% higher risk, while men consuming 30-60 grams (2-6 standard drinks) increased their risk by 15%. For those drinking more than 60 grams daily, the risk escalated to 36%.
“There’s really no safe level of alcohol consumption when it comes to cancer risk,” noted Dr. Adam Saiori, an addiction psychiatrist at the Caron Treatment Center in Pennsylvania.
This study does have its limitations. The researchers indicated that it was an observational study, primarily assessing alcohol intake at a single point in time with a limited representation of Asian groups.
Further research is deemed essential to fully understand the role of lifelong alcohol consumption—like patterns established in early adulthood—and the potential effects of specific consumption behaviors.
Dr. Neha Pathak, an editor at WebMD’s Health and Lifestyle Medicine, emphasized that the study illuminates new and independent risk factors for pancreatic cancer. “It’s crucial to recognize that there are really no safe levels of alcohol when considering cancer risk,” she advised.
These findings reinforce the complexity of the relationship between alcohol and cancer, illustrating just how much more exploration is required regarding different drinking habits and their impact on cancer development.
