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:

  1. 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.
  2. 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.
  3. 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.
  4. 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 daywhich 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.

Empowering Seniors for Safer Online Experiences: 6 Practical Safety Tips for Caregivers and Families

(Family Features) Today’s seniors aren’t shying away from a world that has become increasingly reliant on technology. Quite the opposite, in fact, as recent survey findings suggest adults ages 65 and older are more digitally active and self-assured than ever before. Nearly all seniors surveyed as part of the “Connecting the Digital Dots: Online Habits and Safety Concerns Across Three Generations” survey from Cox Mobile consider themselves digitally literate, using devices for shopping, banking, social media and entertainment. With older adults spending a significant amount of time connected to the digital world – 41% of those surveyed reported spending five or more hours online daily – they’re also more at-risk for scams, viruses like malware and data breaches. Even though 61% of seniors who encountered digital threats were able to mitigate the issues themselves, showing their growing digital capability, increased online engagement brings new challenges and responsibilities for caregivers, who often play a crucial role in supporting seniors’ digital journeys. To help support older loved ones’ safety and confidence as they navigate an evolving digital landscape, Cox Mobile, in partnership with Common Sense Media, offers educational materials on digital safety, smart device use and media literacy for all ages. In addition, these practical safety strategies can help empower seniors to make informed, safe choices online. Encourage Strong Passwords: Simple passwords, like number sequences, keyboard patterns or personal information – such as variations of your name, birthdate, address or names of pets or loved ones – are easily guessable and may lead to issues. While the survey found 70% of seniors already create strong, unique passwords, encourage them to avoid reusing passwords across sites. Recommend a password manager app to safely store passwords and eliminate the need to write them all down, which could lead to a breach if not stored properly. 17746 detail embed2Promote Security Software: If devices aren’t protected, even the most careful users are susceptible to viruses. Though 63% of those surveyed have security software installed, it’s important to regularly make sure it’s up to date (or that automatic updates are enabled) and covers all devices, including laptops, tablets and smartphones. Enable Multi-Factor Authentication: A simple and effective way to stop most attempts at unauthorized account access, 60% of seniors are already using multi-factor authentication as an extra layer of protection. Some seniors, however, may need assistance setting up the safeguard, which typically sends a code to a phone number or email address as part of the login process, for online banking, email or social media accounts. Review Apps and Channels: Over time, it can be easy to accumulate apps on smartphones and tablets. While 51% of surveyed seniors remove unsafe apps, make it a habit to regularly check loved ones’ devices for unfamiliar or suspicious applications and delete them. Also keep an eye out for unauthorized charges, data sharing or browser extensions. Utilize Built-In Safety Features: Explore privacy controls on individual devices (and apps) and check with your loved ones’ internet service provider to ensure security features are being utilized like the 43% of those surveyed who are already taking advantage of their devices’ safety settings. Included privacy protections may include limiting data sharing, disabling location tracking, blocking pop-ups and restricting other unwanted communication. Discuss Online Safety Regularly: Because technology is ever-changing, it’s important for caregivers to talk with senior loved ones about online safety. Open, ongoing conversations, like those one-third of seniors are already having several times a week or even daily, can help build trust and awareness of current scams, suspicious texts or emails, commonly used apps and more. By fostering open dialogue, sharing practical safety strategies and leveraging trusted resources, caregivers can help their loved ones thrive and stay safe.

How to keep dementia from robbing your loved ones of their sense of personhood – tips for caregivers

R. Amanda Cooper, University of Connecticut Every three seconds, someone in the world develops dementia. There are over 6 million people living with dementia in the U.S. and 57 million globally. These figures will only increase in the coming years, as rates of dementia are predicted to double by 2060. If you don’t know someone affected by dementia, you probably will at some point. Dementia is incredibly difficult both for the person experiencing it and for their loved ones, not only because of the symptoms of the disease but also because of the social stigma associated with cognitive decline. Experiencing stigma makes it difficult for people with dementia to ask for help, increases anxiety and depression, and ultimately leads to social isolation. Dementia-related stigma is perpetuated through media messages that portray people with dementia as mindless and incapable, as well as through daily interactions in which others dismiss and dehumanize the person living with dementia. These forms of invalidation – usually unintentional – accelerate and intensify the loss of self-worth and identity that dementia patients are already experiencing. Fortunately, educating and spreading awareness can help reduce behaviors that propagate stigma and dehumanizing treatment of people with dementia. As a social scientist and researcher in interpersonal communication and family caregiving, I explore the social and relational side of dementia. Through my work with these patients and families, I’ve learned that reducing stigma and supporting self-worth for people who have dementia is often done through daily conversations.

How is dementia defined?

Dementia is an umbrella term that refers to a family of cognitive conditions involving memory loss, difficulty thinking or processing information, changes in ability to communicate and challenges with managing daily tasks. The most common form of dementia is Alzheimer’s disease, but there are several other forms of dementia that can severely affect a person’s quality of life and that of their loved ones. Most forms of dementia are progressive, meaning that the symptoms of the disease get steadily worse over time. A person with dementia can live with the disease for several years, and their symptoms will shift as the disease progresses. People in the early stages of dementia, including mild cognitive impairment, continue to engage socially and participate in many of the activities they have always done. In the middle stage of the disease, people often need more help from others to complete daily tasks and may have more difficulty holding conversations. In the late stage, people with dementia are dependent on others and often lose the ability to communicate verbally. Despite the cognitive declines that come with dementia, people living with dementia can maintain many of their former abilities as the disease progresses. Even in the late stages, research shows that people with dementia can understand tone of voice and nonverbal communication such as body language, facial expressions and gentle touch. This makes it clear that people with dementia can continue having meaningful social connections and a sense of self-worth even as their disease progresses.

Focusing care around the person

In the 1990s, psychologist Tom Kitwood, who studied dementia patients in long-term care settings, introduced the notion of “personhood.” Personhood is a recognition of a person’s unique experiences and individual worth. He had observed that residents with dementia were sometimes treated as objects rather than people and were dismissed as being “no longer there” mentally. In response, Kitwood advocated for a new model of person-centered care. In contrast to the medical model of care that was standard at the time, person-centered care aims to provide people with dementia comfort, attachment, inclusion, occupation and identity. Comfort includes both physical and psychological comfort, ensuring that the person with dementia feels safe and is as pain-free as possible. Attachment and inclusion have to do with supporting a person with dementia’s closest relationships and making sure they feel included in social activities. Occupation is about giving the person meaningful activities that are suited to their abilities, while identity is about preserving their unique sense of self. According to Kitwood, each of these elements of personhood can be upheld or threatened through a person’s interactions with others. I find Kitwood’s work particularly important because it suggests that communication is at the heart of personhood.

Communicating to support personhood

So how can family members and friends communicate with their loved one with dementia to help preserve their sense of self? Researchers have identified several evidence-based communication strategies that support person-centered care both in long-term care settings and within the family. These include:

Communication shifts as the disease progresses

Supporting personhood requires adjusting to the communication abilities of the person with dementia. Some communication strategies are helpful in one stage of the disease but not in others. In a recent study, my team and I found that asking the person with dementia to recall the past was affirming for those who were early in the disease and who could still recall the past. But for people who were in later stages of the disease, asking them “Do you remember?” was received more like a test of memory and led to frustration or confusion. Similarly, we found that suggesting words to prompt recall was helpful later in the disease but demeaning for people who were in earlier stages of the disease who could still find their words without help. Providing more help in conversation than is needed can lead people with dementia to withdraw, whereas appropriately adjusting to a person’s communication abilities can empower them to continue to engage socially. Ultimately, supporting a person with dementia’s sense of self and self-worth in conversations is about finding a communication sweet spot – in other words, matching your approach to their current capabilities. Changing your default approach to conversations can be challenging, but making simple communication changes can make all the difference. Meaningful conversations are the key to helping your loved one live their days to the fullest, with a sense of personal worth and a feeling of meaningful connection with others. R.

Easy Pet Wellness Routine: 5 Healthy Habits for Dogs and Cats Without the Fuss

(Family Features) Pets are more than companions – they’re family – and keeping them healthy can be simple, enjoyable and rewarding. Today’s pet parents may be busier than ever, yet they’re also more committed to wellness than previous generations. That means approaching their furry friends’ unique needs with the same balance, care and attention to overall well-being as they do their own. In fact, according to the 2021 Human Animal Bond Research Institute Benchmark Survey of Pet Owners, increased knowledge about the health benefits of the human-animal bond led 91% of pet owners to say they would be more likely to take better care of their pets. Pet health isn’t just about food, however. A holistic approach to wellness combines daily supplements, dental care, exercise, mental enrichment and proactive health, with many owners looking for ways to simplify routines to support their pets every day. These practical ideas can help support a pet’s overall wellness routine. 17690 detail embed2Tailor Flexible Nutrition Plans to Pets’ Needs Every pet is unique, but balanced nutrition forms the foundation of wellness. Dog and cat parents are increasingly seeking customizable food and supplement solutions designed around their furry friend’s age, needs and lifestyle. Age-specific formulations and products featuring natural, minimally processed ingredients and eco-friendly sourcing allow owners to support their pets’ overall health, from mealtime to daily wellness routines. Support Healthy Skin and Coat A pet’s coat often reflects its overall health. Along with a balanced diet and plenty of water, adding a daily supplement can help support a natural shine. While professional grooming keeps dogs and cats looking their best, incorporating regular at-home brushing and bathing with a gentle shampoo strengthens the bond you share and provides an opportunity to spot any changes, like lumps or bumps. Enhance Pet Wellness with Functional Support Even with a balanced diet, many pets may benefit from extra support to maintain their overall well-being. Functional supplements can help target specific needs, including joint mobility, immunity and stress relief. For example, NaturVet’s easy-to-use Lickable supplements – available in Hip & Joint, Calming and Multi-Vitamin formulas for dogs and cats – offer a simple way to make wellness an effortless part of everyday life. Promote Exercise and Mental Enrichment Movement is essential to any wellness routine. Regular walks, agility activities and games help keep pets fit and happy. Physical exercise is only part of the puzzle, though. Interactive toys, puzzle feeders, scent games and agility training help dogs and cats stay mentally sharp, even on days when outdoor activity is limited. Create a Calming Home Environment Dogs and cats can experience stress when routines aren’t followed, just like people. Maintaining a consistent daily schedule and providing a quiet, comfortable space – such as a bed in a low-traffic area – can help promote calm, comfort and security. By taking a few simple, consistent steps each day, pet parents can create a balanced, enjoyable wellness routine that keeps their furry family members healthy, happy and thriving. From functional supplements and daily care habits to exercise, mental enrichment and a calming environment, small efforts can make a big difference, turning everyday care into a rewarding part of life with your pet. To find more practical health and wellness solutions for your pet, visit naturvet.com.   5 Easy Steps to Help Pet Owners Build Healthy Habits Creating a consistent health and wellness routine doesn’t have to be complicated. Consider these simple steps:
  1. Start slow. Introduce new supplements or activities gradually to avoid overwhelming pets.
  2. Be aware. Review product labels and ingredient certifications to ensure they are safe and appropriate for your pet.
  3. Incorporate naturally. Mix functional supplements into meals or use them as a reward for good behavior.
  4. Stay consistent. Small daily actions can add up to long-term health and wellness.
  5. Monitor and adjust. Work with a veterinarian to create a tailored plan and observe your pet’s energy, mobility and mood, adjusting as needed.
