Alcohol is a leading preventable cause of cancer, and alcoholic beverages should carry a warning label as packs of cigarettes do, the U.S. surgeon general said on Friday.
It is the latest salvo in a fierce debate about the risks and benefits of moderate drinking as the influential U.S. Dietary Guidelines for Americans are about to be updated. For decades, moderate drinking was said to help prevent heart attacks and strokes.
That perception has been embedded in the dietary advice given to Americans. However, growing research has linked drinking, sometimes even within the recommended limits, to various types of cancer.
Labels currently affixed to bottles and cans of alcoholic beverages warn about drinking while pregnant or before driving and operating other machinery, and about general “health risks.”
But alcohol directly contributes to 100,000 cancer cases and 20,000 related deaths each year, the surgeon general, Dr. Vivek Murthy, said.
He called for updating the labels to include a heightened risk of breast cancer, colon cancer and at least five other malignancies now linked by scientific studies to alcohol consumption.
“Many people out there assume that as long as they’re drinking at the limits or below the limits of current guidelines of one a day for women and two for men, that there is no risk to their health or well-being,” Dr Murthy said in an interview.
“The data does not bear that out for cancer risk.”
Only Congress can mandate new warning labels of the sort Dr. Murthy recommended, and it’s not clear that the incoming administration would support the change.
