Even 1 drink a day elevates your cancer risk – an expert on how alcohol affects the body breaks down a new government report

Many people use the new year to reflect on their relationship with alcohol. Just-released government guidelines are giving Americans another reason to consider a “dry January.”
Over the past few decades, mounting scientific evidence has shown that as little as 1-2 alcoholic drinks per day can lead to increases in the likelihood of several cancers. This prompted the U.S. surgeon general, Dr. Vivek Murthy, to release a new Surgeon General Advisory on Jan. 3, 2025, warning about the link between alcohol and cancer. This report highlighted the evidence and included a call for new cancer warning labels on alcoholic beverages.
The association between alcohol and cancer isn’t new news – scientists have been trying to determine the link for decades – yet most people aren’t aware of the risks and may only associate drinking with liver disease like cirrhosis. In a 2019 survey from the American Institute for Cancer Research, less than half of Americans identified alcohol as a risk factor for cancer.
Alcohol is the third-most preventable cause of cancer in the U.S, putting it just behind tobacco and obesity. As the surgeon general’s report highlights, alcohol is associated with approximately 100,000 cancer cases and 20,000 cancer deaths every year, playing a role in breast, liver, colorectal, mouth, throat, esophagus and voice box cancer cases. Alcohol-induced cancer deaths outnumber alcohol-associated traffic crash fatalities every year.
The report included the suggestion to add warning labels to alcohol similar to what is already required for tobacco products – another substance of abuse known to cause cancer.
As a neuroscientist specializing in the neurobiological effects of alcohol use and binge drinking, I am glad to see the call to action for reducing alcohol consumption in the United States.
Key takeaways of the report
With so few people aware of the links between alcohol consumption and various cancers – and the fact that the vast majority of people consume some alcohol every week – it’s easy to see why the surgeon general is calling for greater awareness. The 22-page report highlights what scientists know about the relationship between alcohol and cancer, and suggests actions for moving forward. Those include label changes on alcohol, which have not been updated since they were created in 1988.
Somewhat strikingly, breast cancer carries a large portion of this risk – making it particularly worrisome in the face of increased alcohol use among women.
These numbers don’t only apply to heavy alcohol drinkers. While less alcohol is better, 25% of these cancer cases were in people classified as moderate drinkers – consuming, on average, fewer than two drinks per day. This means that anyone regularly drinking alcohol, even small amounts, should know about and understand the risks.
Surgeon general’s advisories are the primary way that the Department of Health and Human Services, where the Office of the Surgeon General resides, communicate health issues of great importance to the public. Surgeon general’s advisories are not necessarily breaking news, but they take the opportunity to bring public awareness to science surrounding big public health issues.
The science behind the link between alcohol and cancer
The relationship between alcohol and cancer has been clear to scientists for decades. In fact, it was highlighted in a 2016 surgeon general’s report as well, which focused on addiction more broadly.
The new report outlines the different types of evidence supporting this link. One way is through epidemiological science, which tries to understand patterns and relationships between the rates of cancer and how much alcohol people consumed. Another is through experimental animal studies, which allow scientists to understand the mechanism and causality of these connections as they apply to specific cancers. Together, studies conclusively show a link and pathway between alcohol consumption and cancer.
The surgeon general’s report highlights four key pathways through which alcohol can cause cancer. These largely focus on the ways alcohol can negatively affect your DNA, the building blocks of cells. While the healthy cells in your body divide all the time, their abnormal growth can be driven by aberrant factors like alcohol-induced DNA damage.
This DNA damage leads to uncontrollable growth of tissue instead of healthy, normal tissue growth. This abnormal tissue growth is cancer. The four pathways through which alcohol can lead to cancer highlighted in the report are:
- The body naturally breaks alcohol down into acetaldehyde. Acetaldehyde can damage and break DNA, leading to chromosomal rearrangements and tumors. This link is so strong that acetaldehyde has been classified as a carcinogen since 1999.
- Alcohol creates reactive oxygen species. Reactive oxygen species, sometimes called “free radicals,” are unstable molecules that contain oxygen and can further damage DNA, proteins and fats.
- Alcohol can influence hormones, like estrogen. Alcohol can raise the amount of estrogen in the body, which may explain its link to breast cancer. This increased estrogen can influence breast tissue by causing – you guessed it – DNA damage.
- Alcohol is a solvent, which means other things can dissolve in it. This makes it easier for carcinogens from other sources – like cigarettes and e-vapes – to be absorbed by the body when the two are consumed together.

Is any amount of alcohol safe?
The biggest question on people’s minds right now is likely “how much alcohol can I safely drink?” and the answer to that might disappoint you – probably none.
Alcohol use remains one of the most preventable risk factors for cancer. And even moderate alcohol consumption – one or fewer drinks per day – may elevate cancer risk for some types, such as breast, throat and mouth cancers.
But none of these studies can tell you what your individual risk for cancer is. The relationship between alcohol and cancer can be influenced by your genes, such as those that control the enzymes that metabolize alcohol, and other lifestyle factors that influence the rates of cancer broadly, like diet and inflammation. All of these lifestyle and personal health factors can influence how risky alcohol consumption is for you.
The Centers for Disease Control and Prevention notes that if you choose to drink, consider sticking to less than one, for women, or two, for men, standard servings of alcohol per day – which might be smaller than you think, and don’t binge drink alcohol at all. The surgeon general is also suggesting a rethinking of these guidelines to include updated limits on daily alcohol consumption and greater educational efforts around the link between alcohol and cancer.
The National Institute on Alcohol Abuse and Alcoholism has similar recommendations around limiting alcohol consumption and advises that for people who choose to drink alcohol, “the less, the better.”
The institute offers tips on its website for managing your alcohol consumption or abstaining from alcohol consumption altogether, including finding alternative hobbies and activities, identifying what leads to your urges to drink and having a plan to handle urges, and identifying a strategy for saying “no” to an alcoholic beverage in social settings.

Seeing the Possibilities: Living with Low Vision
Millions of Americans face challenges due to low vision, a condition that is not an inevitable part of aging. February’s Low Vision Awareness Month highlights the importance of eye exams and awareness. Effective management strategies include environmental modifications, assistive devices, and vision rehabilitation services to improve daily living and maintain independence.

(Family Features) Millions of Americans are living with low vision, a visual impairment that can turn everyday moments – recognizing a friend’s face across the street, reading a recipe or checking a text message – into unexpected challenges.
Low vision isn’t a natural part of getting older, though the conditions that cause it do become more common with age.
Whether low vision is affecting you or a loved one, Low Vision Awareness Month is a perfect time to have your eyes examined for signs of eye diseases and to take steps to make daily life easier if you are experiencing low vision.
Consider this information from the National Eye Institute to make the most of your vision and improve your quality of life.
Understanding low vision
You may have low vision if you can’t see well enough to read, drive, recognize faces, distinguish colors or see screens clearly.
Many different eye conditions can cause low vision, but the most common causes are age-related macular degeneration, cataracts, glaucoma and diabetic retinopathy, a condition that can cause vision loss in people with diabetes.
The most common types of low vision are:
- Central vision loss (not being able to see things in the center of your vision)
- Peripheral vision loss (not being able to see things out of the corners of your eyes)
- Night blindness (not being able to see in low light)
- Blurry or hazy vision
Diagnosing low vision
Your doctor can check for low vision as part of a simple, painless comprehensive dilated eye exam. He or she will ask you to read letters that are up close and far away and will check whether you can see things in the center and at the edges of your vision.
Then eye drops are used to widen your pupils and check for other eye problems – including conditions that could cause low vision.
Low vision is usually permanent, but glasses, medicine or surgery may help with daily activities or slow progression.
Living with low vision
If you have low vision, you aren’t alone. There are steps you can take to make life easier.
For minor vision loss, simple adjustments like using brighter lights, wearing anti-glare sunglasses and using magnifiers can help. Changing the settings on your phone and computer to increase contrast, make text larger or have the device read out loud may also help.
If your vision loss is getting in the way of everyday activities, ask your eye doctor about vision rehabilitation. These services can give you skills and resources to help manage your daily life and keep your independence. Examples include:
- Employment and job training
- Environmental modifications, like improving lighting and contrast
- Assistive devices and technologies, like magnifiers, filters and screen readers
- Adaptive strategies for daily living and independent living skills training
- Emotional support, like counseling or support groups
- Transportation and household services
Finding the right vision rehabilitation services and support may take time, but working closely with your eye doctor or care team is an important first step. Discuss your needs and goals for living with your visual impairment so they can help identify the best services for you.

How to avoid seeing disturbing video on social media and protect your peace of mind
How to avoid seeing disturbing video on social media and protect your peace of mind

How to avoid seeing disturbing video on social media and protect your peace of mind
When graphic videos like those of the recent shooting of a protester by federal agents in Minneapolis go viral, it can feel impossible to protect yourself from seeing things you did not consent to see. But there are steps you can take.
Social media platforms are designed to maximize engagement, not protect your peace of mind. The major platforms have also reduced their content moderation efforts over the past year or so. That means upsetting content can reach you even when you never chose to watch it.
You do not have to watch every piece of content that crosses your screen, however. Protecting your own mental state is not avoidance or denial. As a researcher who studies ways to counteract the negative effects of social media on mental health and well-being, I believe it’s a way of safeguarding the bandwidth you need to stay engaged, compassionate and effective.
Why this matters
Research shows that repeated exposure to violent or disturbing media can increase stress, heighten anxiety and contribute to feelings of helplessness. These effects are not just short-term. Over time, they erode the emotional resources you rely on to care for yourself and others.
Protecting your attention is a form of care. Liberating your attention from harmful content is not withdrawal. It is reclaiming your most powerful creative force: your consciousness.
Just as with food, not everything on the table is meant to be eaten. You wouldn’t eat something spoiled or toxic simply because it was served to you. In the same way, not every piece of media laid out in your feed deserves your attention. Choosing what to consume is a matter of health.
And while you can choose what you keep in your own kitchen cabinets, you often have less control over what shows up in your feeds. That is why it helps to take intentional steps to filter, block and set boundaries.
Practical steps you can take
Fortunately, there are straightforward ways to reduce your chances of being confronted with violent or disturbing videos. Here are four that I recommend:
- Turn off autoplay or limit sensitive content. Note that these settings can vary depending on device, operating system and app version, and can change.
https://datawrapper.dwcdn.net/d1deR/2
- Use keyword filters. Most platforms allow you to mute or block specific words, phrases or hashtags. This reduces the chance that graphic or violent content slips into your feed.
- Curate your feed. Unfollow accounts that regularly share disturbing images. Follow accounts that bring you knowledge, connection or joy instead.
- Set boundaries. Reserve phone-free time during meals or before bed. Research shows that intentional breaks reduce stress and improve well-being.

Reclaim your agency
Social media is not neutral. Its algorithms are engineered to hold your attention, even when that means amplifying harmful or sensational material. Watching passively only serves the interests of the social media companies. Choosing to protect your attention is a way to reclaim your agency.
The urge to follow along in real time can be strong, especially during crises. But choosing not to watch every disturbing image is not neglect; it is self-preservation. Looking away protects your ability to act with purpose. When your attention is hijacked, your energy goes into shock and outrage. When your attention is steady, you can choose where to invest it.
You are not powerless. Every boundary you set – whether it is turning off autoplay, filtering content or curating your feed – is a way of taking control over what enters your mind. These actions are the foundation for being able to connect with others, help people and work for meaningful change.
More resources
I’m the executive director of the Post-Internet Project, a nonprofit dedicated to helping people navigate the psychological and social challenges of life online. With my team, I designed the evidence-backed PRISM intervention to help people manage their social media use.
Our research-based program emphasizes agency, intention and values alignment as the keys to developing healthier patterns of media consumption. You can try the PRISM process for yourself with an online class I launched through Coursera in October 2025. You can find the course, Values Aligned Media Consumption, on Coursera. The course is aimed at anyone 18 and over, and the videos are free to watch.

Understanding Cardiovascular Disease Risk Factors: Numbers to Know in 2026
The American Heart Association’s 2026 update reveals a decrease in deaths from heart disease and stroke, despite rising rates of high blood pressure, diabetes, and obesity. Following their Life’s Essential 8 guidelines can prevent 40% of cardiovascular deaths, emphasizing the importance of healthier lifestyles for improved heart health.

Understanding Cardiovascular Disease Risk Factors: Numbers to Know in 2026
(Family Features) Taking care of your heart with healthy behaviors may be at the top of your wellness priority list already, and there may be good news about the effects of adhering to expert recommendations.
New information from the American Heart Association’s 2026 Heart Disease & Stroke Statistics Update shows deaths from heart disease and stroke are on the decline. However, rates continue to climb for high blood pressure, diabetes and obesity – all of which are health risk factors that contribute to cardiovascular disease.
Following expert guidance can be your prescription for better health as 80% of heart disease and stroke is preventable.
To help maintain and improve your cardiovascular health, consider following the American Heart Association’s Life’s Essential 8, which is a set of four health behaviors (eat better, be more active, quit tobacco and get healthy sleep) and four health factors (manage weight, control cholesterol, manage blood sugar and manage blood pressure).
In the United States, optimal Life’s Essential 8 scores could prevent up to 40% of annual all-cause and cardiovascular disease deaths among adults.
Consider these highlights from the statistics update:
- Heart disease remains the leading cause of death in the U.S. and stroke is the No. 4 leading cause of death.
- Together, heart disease and stroke accounted for more than a quarter of all deaths in the U.S. in 2023.
- Cardiovascular diseases, including all types of heart disease and stroke, claim more lives in the U.S. each year than all forms of cancer and accidental deaths — the Nos. 2 and 3 causes of death – combined.
- On average, every 34 seconds, someone died of cardiovascular disease in 2023.
- On average, about two people died of heart disease every 3 minutes in the U.S. in 2023.
- On average in 2023, someone died of stroke every 3 minutes, 14 seconds in the U.S.
- Nearly half of U.S. adults now have high blood pressure.
- Nearly 29.5 million U.S. adults have diagnosed diabetes.
- About 50% of U.S. adults have obesity or severe obesity, and 28.1% of youth ages 2-19 have obesity.
- Only 1 in 4 U.S. adults meets national physical activity guidelines. Only 1 in 5 U.S. youths ages 6-17 are physically active for 60 minutes or more every day of the week.
