Evidence suggests “one or fewer drinks per day” may elevate the risk for cancers.
January 6, 2025
The US Surgeon General has issued an advisory recommending updates to alcoholic beverage labels to include warnings about the risks of cancer.
The document, titled Surgeon General’s Advisory on Alcohol and Cancer Risk, addressed the “direct link” between alcohol consumption and an increased risk of cancer.
According to the advisory, alcohol is the “third leading preventable cause” of cancer in the US, following tobacco use and obesity.
It underscored that alcohol consumption contributed to cancers of the breast, colorectum, oesophagus, liver, mouth, throat, and voice box, regardless of the alcohol type.
Cancer risk increases with alcohol intake, and evidence suggests that even low levels—such as “one or fewer drinks per day” —can elevate the risk for breast, mouth, and throat cancers, according to a statement from the Surgeon General’s office.
Dr Murthy called for revising the Surgeon General’s health warning labels on alcohol-containing beverages to include information about cancer risks.
This advisory also emphasised the need to reevaluate recommended limits for alcohol consumption based on the latest research to account for cancer risks.
Dr Murthy said: “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 US – greater than the 13,500 alcohol-associated traffic crash fatalities per year in the US – yet the majority of Americans are unaware of this risk.
“This advisory lays out steps we can all take to increase awareness of alcohol’s cancer risk and minimise harm.”
The release also urged public health professionals and community groups to emphasise alcohol consumption “as a leading modifiable cancer risk factor” and improve education efforts to raise public awareness.
The surgeon general advised people to consider the link between alcohol consumption and increased cancer risk “when deciding whether to drink or how much to have”.
The action comes in response to a 2020 letter addressed to Dr Murthy by the Center for Science in the Public Interest, American Institute for Cancer Research, Consumer Federation of America, and US Alcohol Policy Alliance, urging an update to alcoholic beverage labels to include cancer warnings.
In May 2023, Ireland became the “first” country in the European Union to mandate health labelling on alcoholic drinks with the law anticipated to take effect from 22 May 2026.
The Canadian Centre on Substance Use and Addiction (CCSA) issued new guidance in 2023, warning that no level of alcohol consumption is risk-free and recommended a maximum of two drinks per week.

5 surprising benefits of #walking: Any physical activity is a boon to your overall health. But walking in particular comes with a host of benefits. https://bit.ly/3uyNvhI#HarvardHealth
The next time you have a check-up, don’t be surprised if your doctor hands you a prescription to walk. Yes, this simple activity that you’ve been doing since you were about a year old is now being touted as “the closest thing we have to a wonder drug,” in the words of Dr. Thomas Frieden, former director of the Centers for Disease Control and Prevention.
Of course, you probably know that any physical activity, including walking, is a boon to your overall health. But walking in particular comes with a host of benefits. Here’s a list of five that may surprise you.
1. It counteracts the effects of weight-promoting genes. Harvard researchers looked at 32 obesity-promoting genes in over 12,000 people to determine how much these genes actually contribute to body weight. They then discovered that, among the study participants who walked briskly for about an hour a day, the effects of those genes were cut in half.
2. It helps tame a sweet tooth. A pair of studies from the University of Exeter found that a 15-minute walk can curb cravings for chocolate and even reduce the amount of chocolate you eat in stressful situations. And the latest research confirms that walking can reduce cravings and intake of a variety of sugary snacks.
3. It reduces the risk of developing breast cancer. Researchers already know that any kind of physical activity blunts the risk of breast cancer. But an American Cancer Society study that zeroed in on walking found that women who walked seven or more hours a week had a 14% lower risk of breast cancer than those who walked three hours or fewer per week. And walking provided this protection even for the women with breast cancer risk factors, such as being overweight or using supplemental hormones.
4. It eases joint pain. Several studies have found that walking reduces arthritis-related pain, and that walking five to six miles a week can even prevent arthritis from forming in the first place. Walking protects the joints — especially the knees and hips, which are most susceptible to osteoarthritis — by lubricating them and strengthening the muscles that support them.
5. It boosts immune function. Walking can help protect you during cold and flu season. A study of over 1,000 men and women found that those who walked at least 20 minutes a day, at least 5 days a week, had 43% fewer sick days than those who exercised once a week or less. And if they did get sick, it was for a shorter duration, and their symptoms were milder.
What Does Alcohol Do to Your Body? 9 Ways Alcohol Affects Your Health
Alcohol affects your whole body, from your liver and immune system to your brain and mental health
You probably already know that excessive drinking can affect you in more ways than one.
There are the empty calories that can lead to weight gain. There’s the potential for injury and regrettable choices. And don’t forget about the hangovers of course.
Heavy drinking can also lead to a host of health concerns, like brain damage, heart disease, cirrhosis of the liver and even certain kinds of cancer.
And that’s on top of the toll that alcohol use can take on relationships, not to mention the potential for financial strain and legal troubles.
But even moderate alcohol use changes the way your body functions.
We talked with hepatologist Shreya Sengupta, MD, about how alcohol use affects your body and your emotional health.
“Some people think of the effects of alcohol as only something to be worried about if you’re living with alcohol use disorder, which was formerly called alcoholism,” Dr. Sengupta says.
“But when you consider how alcohol is metabolized and used by your body, we can start to see that even moderate and social drinking affects our health to some degree.”
Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body.
Liver
Your liver detoxifies and removes alcohol from your blood through a process known as oxidation. When your liver finishes that process, alcohol gets turned into water and carbon dioxide.
But when you ingest too much alcohol for your liver to process in a timely manner, a buildup of toxic substances begins to take a toll on your liver.
If alcohol continues to accumulate in your system, it can destroy cells and, eventually, damage your organs.
“When your liver is overwhelmed by oxidizing alcohol, it generates molecules that inhibit fat oxidation,” Dr. Sengupta explains. “The fats build up. Over time, it can lead to a condition known as steatotic liver disease.”
Steatotic liver disease used to go by the name fatty liver disease.
Steatotic liver disease develops in about 90% of people who drink more than 1.5 to 2 ounces of alcohol per day. That’s about one shot glass worth.
With continued alcohol use, steatotic liver disease can lead to liver fibrosis. Eventually, you can develop permanent and irreversible scarring in your liver, which is called cirrhosis.
“The good news is that earlier stages of steatotic liver disease are usually completely reversible in about four to six weeks if you abstain from drinking alcohol,” Dr. Sengupta assures.
Cirrhosis, on the other hand, is irreversible and can lead to liver failure and liver cancer, even if you abstain from alcohol.
Metabolism
You probably are keenly aware of the so-called “beer belly.” That’s shorthand for a round midsection that some people associate with drinking too much beer.
In reality, there’s no evidence that drinking beer (or your alcoholic beverages of choice) actually contributes to belly fat.
But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general. Even for people who aren’t particularly heavy drinkers.
“Drinking gives your body work to do that keeps it from going about its other processes,” Dr. Sengupta notes. “Alcohol distracts your system from its regularly scheduled duties, including things like metabolizing carbohydrates and fats.”
Once you take a drink, your body makes metabolizing alcohol a priority — above processing anything else.
That’s because your body already has processes in place that allow it to store excess proteins, carbohydrates and fats. But there isn’t a storage tank for alcohol. So, your system prioritizes getting rid of alcohol before it can turn its attention to its other work.
That allows excess calories from the foods you eat to sit around, leading to weight gain.
Gut health
Your gut microbiome is a hotbed of bacteria that help keep your digestive system happy and healthy. The trillions of microbes in your colon and large and small intestines are critical to proper digestion. They also help fend off inflammation and support healthy metabolism.
When you drink too much alcohol, it can throw off the balance of good and bad bacteria in your gut.
“Alcohol can kill the good bacteria that live in your gut, allowing bad bacteria to grow unchecked,” Dr. Sengupta explains. “That can lead to problems with digestion, inflammation and even organ damage.”
Having a glass of wine with dinner or a beer at a party here and there isn’t going to destroy your gut. But even low amounts of daily drinking and prolonged and heavy use of alcohol can lead to significant problems for your digestive system.
There are a few studies that associate red wine with improved heart health in lab tests. But no research proves that red wine causes any improvements in heart health in people.
“The reality is that alcohol causes more health troubles than it could ever help,” Dr. Sengupta reinforces. “And that goes for your heart, as well as the rest of your body.”
Pancreas
Your pancreas helps your body digest food and manage your blood sugar. Drinking alcohol changes how your pancreas works.
“Your pancreas secretes fluids. Alcohol use can thicken those fluids, which can clog the ducts that those fluids flow out of,” Dr. Sengupta explains.
Like a clog in a drain, those thickened fluids can jam up your ducts. That can lead to pancreatitis, which is inflammation of the pancreas.
Pancreatitis can be a short-term (acute) condition that clears up in a few days. But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe.
Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA. Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors.
Alcohol use has been shown to raise your risk for several kinds of cancer. That includes cancers of the:
Mouth.
Esophagus.
Throat.
Liver.
Breast.
Colon and rectum.
Immune system
If you drink every day, or almost every day, you might notice that you catch colds, flu or other illnesses more frequently than people who don’t drink. That’s because alcohol can weaken your immune system and make your body more susceptible to infection.
“We see lower levels of a specific kind of white blood cells called lymphocytes in people who drink heavily for long periods of time,” Dr. Sengupta reports. “That can leave them more vulnerable to infectious diseases.”
Brain
The morning after a night of over-imbibing can cause some temporary effects on your brain. Things like trouble concentration, slow reflexes and sensitivity to bright lights and loud sounds are standard signs of a hangover, and evidence of alcohol’s effects on your brain.
Long-term alcohol use can change your brain’s wiring in much more significant ways. Ways that your standard hangover cures won’t even begin to touch.
“Excessive alcohol consumption can cause nerve damage and irreversible forms of dementia,” Dr. Sengupta warns.
Mental health
Alcohol is a depressant. And prolonged alcohol use can lead to mental health conditions like anxiety and depression. Chronic misuse can also lead to paranoia and hallucinations.
Even drinking a little too much (binge drinking) on occasion can set off a chain reaction that affects your well-being. Lowered inhibitions can lead to poor choices with lasting repercussions — like the end of a relationship, an accident or legal woes. Each of those consequences can cause turmoil that can negatively affect your long-term emotional health.
“Alcohol tends to cause more problems than it solves for a lot of people,” Dr. Sengupta emphasizes. “If drinking is affecting your health, your relationships, your work, your finances, it’s time to make some serious changes.”
If you need more guidance to quit drinking, the Substance Abuse and Mental Health Services Administration (SAMHSA) offers a hotline, 24/7, 365 days a year. Call 1.800.662.HELP (4357).
Alcoholics Anonymous is available almost everywhere and provides a place to openly and nonjudgmentally discuss alcohol issues with others who have alcohol use disorder.

“The reality is that alcohol causes more health troubles than it could ever help,” Dr. Sengupta reinforces. “And that goes for your heart, as well as the rest of your body.”
Pancreas
Your pancreas helps your body digest food and manage your blood sugar. Drinking alcohol changes how your pancreas works.
“Your pancreas secretes fluids. Alcohol use can thicken those fluids, which can clog the ducts that those fluids flow out of,” Dr. Sengupta explains.
Like a clog in a drain, those thickened fluids can jam up your ducts. That can lead to pancreatitis, which is inflammation of the pancreas.
Pancreatitis can be a short-term (acute) condition that clears up in a few days. But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe.
Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA. Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors.
Alcohol use has been shown to raise your risk for several kinds of cancer. That includes cancers of the:
Mouth.
Esophagus.
Throat.
Liver.
Breast.
Colon and rectum.
Immune system
If you drink every day, or almost every day, you might notice that you catch colds, flu or other illnesses more frequently than people who don’t drink. That’s because alcohol can weaken your immune system and make your body more susceptible to infection.
“We see lower levels of a specific kind of white blood cells called lymphocytes in people who drink heavily for long periods of time,” Dr. Sengupta reports. “That can leave them more vulnerable to infectious diseases.”
Brain
The morning after a night of over-imbibing can cause some temporary effects on your brain. Things like trouble concentration, slow reflexes and sensitivity to bright lights and loud sounds are standard signs of a hangover, and evidence of alcohol’s effects on your brain.
Long-term alcohol use can change your brain’s wiring in much more significant ways. Ways that your standard hangover cures won’t even begin to touch.
“Excessive alcohol consumption can cause nerve damage and irreversible forms of dementia,” Dr. Sengupta warns.
Mental health
Alcohol is a depressant. And prolonged alcohol use can lead to mental health conditions like anxiety and depression. Chronic misuse can also lead to paranoia and hallucinations.
Even drinking a little too much (binge drinking) on occasion can set off a chain reaction that affects your well-being. Lowered inhibitions can lead to poor choices with lasting repercussions — like the end of a relationship, an accident or legal woes. Each of those consequences can cause turmoil that can negatively affect your long-term emotional health.
“Alcohol tends to cause more problems than it solves for a lot of people,” Dr. Sengupta emphasizes. “If drinking is affecting your health, your relationships, your work, your finances, it’s time to make some serious changes.”
If you need more guidance to quit drinking, the Substance Abuse and Mental Health Services Administration (SAMHSA) offers a hotline, 24/7, 365 days a year. Call 1.800.662.HELP (4357).
Alcoholics Anonymous is available almost everywhere and provides a place to openly and nonjudgmentally discuss alcohol issues with others who have alcohol use disorder.
