U.S. Surgeon General Dr. Vivek Murthy issued a new advisory highlighting the cancer risks associated with alcohol consumption. The advisory, released Friday, links alcohol to seven types of cancer, including throat, liver, esophageal, mouth, larynx, colon, and rectal cancers. It emphasizes that alcohol is the third leading preventable cause of cancer in the U.S., following tobacco and obesity.
The advisory aims to raise awareness, noting that alcohol contributes to about 100,000 cancer cases and 20,000 cancer deaths annually in the United States. This figure surpasses the 13,500 alcohol-related traffic fatalities each year. Despite these statistics, many Americans remain unaware of alcohol’s cancer risks.
- Alcohol and Cancer Risks: U.S. Surgeon General Dr. Vivek Murthy links alcohol consumption to seven cancers, including liver, throat, and colon cancers, contributing to 100,000 cases and 20,000 deaths annually.
- Mechanisms of Harm: Alcohol increases cancer risk by producing DNA-damaging acetaldehyde, inducing oxidative stress, altering hormones like estrogen, and facilitating carcinogen absorption.
- Call for Action: Recommendations include updated warning labels, stricter consumption guidelines, and greater public awareness of alcohol’s health risks.
- No Safe Level of Consumption: Experts, including Dr. Marc Siegel, stress that alcohol, even in moderation, is a toxin linked to cancer and other diseases.
Dr. Murthy’s advisory details four mechanisms through which alcohol increases cancer risk. Alcohol breaks down into acetaldehyde, a chemical that damages DNA, and induces oxidative stress, affecting protein, DNA, and cell integrity. It also alters hormone levels, such as estrogen, increasing breast cancer risk. Additionally, alcohol facilitates the absorption of carcinogens in the body.
The advisory calls for updated warning labels on alcoholic beverages to inform consumers about cancer risks. It suggests reevaluating guideline limits for alcohol consumption and encourages health professionals to emphasize the link between alcohol and cancer.
Dr. Marc Siegel from NYU Langone Health supports the advisory, highlighting the misconception that moderate alcohol consumption is harmless. He stresses that alcohol is a proven toxin linked to liver, heart, and brain diseases.
While some believe moderate alcohol consumption can relieve stress, Dr. Siegel warns that no amount of alcohol is truly healthy. The advisory arrives at a critical time, following reports of increased alcohol use during the pandemic due to stress and social isolation.
The surgeon general’s recommendations underscore the need for public education on alcohol’s health risks, calling for comprehensive measures to address this significant public health issue.
