The U.S. Surgeon General, Dr. Vivek Murthy, says drinking alcohol can cause cancer – even in moderation. In fact, he is calling for all alcoholic beverages to carry warning labels to inform the public of the danger, much like cigarettes were required to do many years ago.
“Alcohol is a well-established, preventable cause of cancer responsible for about 100,000 cases of cancer and 20,000 cancer deaths annually in the United States,” Dr. Vivek Murthy said in his advisory issued Friday. “Yet the majority of Americans are unaware of this risk.”
Laura Cooper and Brianna Abbott, writing for The Wall Street Journal, tell us “An act of Congress would be required to change the existing warning labels on bottles of beer, wine and liquor. Today, federal rules require only a warning against drunken driving and drinking while pregnant, as well as a general warning that alcohol “may cause health problems.”
Alcohol consumption is the third leading preventable cause of cancer in the U.S., after tobacco and obesity. The link between alcohol consumption and cancer risk has been established for at least seven types of cancer, including breast, colorectum, esophagus, liver, mouth, throat and voice box, Murthy said.
The Distilled Spirits Council, a spirits industry group, pointed to recent research from the National Academies of Sciences, Engineering and Medicine concluding that men who consumed two drinks a day and women who consumed one drink a day had lower all-cause mortality rates than people who never drank alcohol. The same report also found a link between alcohol consumption and breast cancer risk. “Many lifestyle choices carry potential risks,” and the government should consider the entire body of scientific research, the spirits council said.
Obviously, this council has an inherit bias since they represent an industry that profits from the sale of alcohol. But are there differing opinions on this issue in the scientific literature?
Allysia Finley, also writing for The Wall Street Journal, says yes. She says, “Surgeon General Vivek Murthy has done more to politicize science and erode trust in public-health leaders than anyone other than Anthony Fauci. Dr. Murthy was at it again on Friday with a headline-grabbing report that recommends alcohol be distributed with cancer warnings.
She notes two weeks earlier the National Academies of Sciences, Engineering and Medicine released a congressionally mandated review of the recent evidence on the health effects of moderate drinking, or up to one drink a day for women and two for men. Its more than 200 pages of findings run counter to Dr. Murthy’s 22-page report, though they got scant attention in the press.
The academies found insufficient evidence to support a link between moderate drinking and oral, pharyngeal, esophageal, laryngeal and other cancers. It did find a slightly higher risk of breast cancer with moderate drinking but also a lower risk of death generally and from cardiovascular disease specifically compared with never drinking.
Finley says, “More government is Dr. Murthy’s prescription for every social and public-health ailment. Given this record, why would anyone take his latest warning about alcohol and cancer seriously?”
Since I was in medical school in the 1970s, we have known that excessive use of alcohol is related to certain cancers such mouth, throat, esophagus, liver, colon and breast. Yet there has been little evidence it is correlated with occasional to moderate alcohol usage. In fact, occasional use of alcohol, especially red wine, has been associated with reduced cardiovascular risk. This new surgeon general report is a deviation from this prior information.
If this is really more about political ideology than science, I would expect some pushback from the medical community in the near future, especially after the inauguration of our new president. Let’s wait and see.
