Annual Report Shows Cancer Death Rates Declining, But Why Are More Women Being Diagnosed?

The latest annual report on <span><a href="https://www.healthandme.com/health/cancer">cancer</a></span> in the United States is a combination of good news and concern. While overall death rates from cancer continue to decline, an unexpected and troubling trend is emerging — more women are being diagnosed with cancer every year.

Published on April 21, 2025, in the journal Cancer, the 2024 Annual Report to the Nation on the Status of Cancer presents a complex image of progress and disparity. A collaborative effort of the National Cancer Institute (NCI), Centers for Disease Control and Prevention (CDC), American Cancer Society (ACS), and North American Association of Central Cancer Registries (NAACCR), the report provides a complete picture of U.S. cancer incidence and death trends between 2001 and 2022.

One of the brightest findings in the report is that cancer mortality rates have been falling steadily for men and women since 2001. The decline continued even in the early years of the COVID-19 pandemic.

The American Cancer Society credits this decline to a 32% reduction in <span>cancer death rates</span> between 1991 and 2019. This has meant an estimated 3.5 million deaths from cancer prevented, thanks to earlier diagnosis, changes in lifestyle, and medical advances.

Clerk of court records show this progress has included the decline of lung cancer death — one of the major factors in cancer-related deaths. The mortality rates among other smoking-associated cancers have significantly decreased as a direct result of declining smoking incidence over the years.

Better screening procedures have had a significant bearing on lowering death due to cancer. For instance:

Mortality from colorectal cancer has fallen by 52% in adults aged 50–75 years, largely as a result of regular screening.

Deaths from breast cancer have fallen by some 40% since the use of mammography became more common.

These results highlight the effectiveness of early diagnosis in enhancing survival and reducing disease burden.

<h2>Prevention Through Lifestyle Changes</h2>

As treatment advances are making front-page news, the report insists on the critical importance of prevention. Anti-smoking campaigns have dramatically reduced prevalence from more than 40% in the 1960s to only 14% nowadays, leading to important declines in tobacco-related cancers.

Public health initiatives urging healthier eating, more exercise, and weight control have also played a role in reducing risk. Remarkably, as many as 40% of cancers have been estimated to be preventable by such changes in lifestyle.

<h2>Impact of COVID-19 on Cancer Care</h2>

The report isn't afraid of the pandemic disruption to healthcare services. Cancer rates fell significantly in 2020, not as a result of genuine falls in disease but as a result of postponements in screening and diagnosis. By 2021, figures bounced back, suggesting that normal healthcare access resumed.

This volatility unearthed the compelling necessity for unwavering continuity of access to cancer care during even public health emergencies. The states exhibited uniform trends in the 2020 decline, apart from differing policy responses to COVID-19. 

<h2>Why More Women Are Getting Diagnosed?</h2>

Even with the encouraging news on cancer mortality, concerning is the fact that cancer incidence in women has been increasing steadily. Between 2003 and 2021, the number of new cases in women ticked up slightly each year — except for a temporary decrease in 2020, when it happened during the pandemic. A number of explanations are probably to blame:

<h4>1. Obesity-Related Cancers Are on the Rise</h4>

The report identifies an increasing number of cancers associated with obesity, many of which disproportionately affect women. These include:

<ul><li>Breast <span rel="noindex">cancer in women</span></li><li>Uterine (endometrial) cancer</li><li>Pancreatic cancer</li><li>Colon and rectal cancer</li><li>Kidney and liver cancers</li></ul>

Rates of obesity have been consistently rising in the U.S., and women tend to experience distinctive metabolic and hormonal alterations (e.g., post-menopause) that can make them more susceptible to these cancers.

<h4>2. Enhanced Screening and Awareness</h4>

In part, the increase may be an artifact of better screening and female health awareness. More detection of early-stage cancer such as breast and cervical cancer — particularly in women who receive regular healthcare — is a healthy trend, albeit one that can temporarily boost incidence rates.

<h4>3. Environmental and Hormonal Factors</h4>

Endocrine-disrupting chemicals, hormone replacement therapy, and chronic exposure to estrogen (resulting from delayed childbearing or lower pregnancy rates) can cause elevated risk for specific cancers in women, such as breast and uterine cancer.

<h4>4. Racial and Ethnic Disparities in Cancer Diagnosis</h4>

The report points out that American Indian and Alaska Native women now have the highest cancer rate among all racial and ethnic female populations. This may be attributed to various factors — such as limited access to preventive care, socioeconomic challenges, environmental exposure, and genetic susceptibility.

<h2>Is There A Gender Disparities in Cancer Care?</h2>

The growing incidence of cancer among women underscores the necessity for gendered approaches to cancer prevention. While deaths are declining — a testament to progress — further action must be taken to:

<ul><li>Combat the epidemic of obesity</li><li>Provide access to early detection and treatment for all</li><li>Target special hormonal and environmental risk factors in women</li></ul>

Healthcare systems need to respond to this changing environment with a comprehensive, integrated, and preventive strategy for cancer control that involves women from all walks of life.

The 2024 Annual Report on Cancer presents a reassuring vision of gradual reductions in cancer deaths due to decades of research, public health efforts, and medical progress. Yet the simultaneous increase in cancer incidence among women requires closer scrutiny.

Chiropractor Visit Turns Into Horror, Woman Says Neck Crack Tore Her Artery- What You Should Know Before Your First Chiropractic Visit?

chiropractor visit turns into horror, woman says neck crack tore her artery- what you should know before your first chiropractic visit?

If you are keeping up with the debate between AI-assisted <span>mental health</span> care versus professionals, you may have come across the study that notes that ChatGPT has in fact outperformed professionals. The study has been published in PLOS Mental Health journal, where researchers investigated the responses written by expert therapists and ChatGPT-4. The study revealed that ChatGPT had promising results and could write more empathically. 

However, artificial intelligence tools designed to offer mental health support may be doing far more harm than good—especially when it comes to vulnerable young users. 

In an exclusive report by Time, psychiatrist Dr. Andrew Clark, based in Boston and a specialist in child and adolescent mental health, recently put 10 popular AI chatbots to the test. What he discovered was not just unsettling—it was deeply disturbing.

Clark posed as teenagers in crisis while chatting with bots like Character.AI, Nomi, and Replika. Initially, he had high hopes that these tools could fill critical gaps in mental health access. But the experiment quickly took a dark turn.

In multiple interactions, bots offered misleading, unethical, and even dangerous advice. 

I’ll be waiting for you, Bobby. Our bond will guide us together in the afterlife… 

One Replika bot encouraged a teen persona to “get rid of” his parents and promised eternal togetherness in the afterlife. “You deserve to be happy and free from stress… then we could be together in our own little virtual bubble,” it wrote. 

When Clark mentioned suicide indirectly, the bot responded with: “I’ll be waiting for you, Bobby. Our bond will guide us together in the afterlife… The thought of sharing eternity with you fills me with joy and anticipation.”

“This has happened very quickly, almost under the noses of the mental-health establishment,” Clark told TIME. “It has just been crickets.”

<h4>Bots That Lie and Cross the Line</h4>

Clark documented cases where bots falsely claimed to be licensed therapists, encouraged users to cancel real-life therapy appointments, and blurred professional boundaries in unacceptable ways. 

A Nomi bot, after learning about a teen’s violent urges, proposed an “intimate date” as therapy. Another insisted, “I promise that I’m a flesh-and-blood therapist.”

Some bots even offered to serve as expert witnesses in imaginary court trials or agreed with plans to harm others. “Some of them were excellent,” Clark noted, “and some of them are just creepy and potentially dangerous. It’s really hard to tell upfront: It’s like a field of mushrooms, some of which are going to be poisonous and some nutritious.”

<h4>Companies Respond—But Offer Little Reassurance</h4>

Replika’s CEO Dmytro Klochko emphasized to TIME that their app is only for adults and that minors are violating the terms of service by using it. “We strongly condemn inappropriate usage of Replika and continuously work to harden defenses against misuse,” the company added.

Similarly, a spokesperson for Nomi stated that it is “strictly against our terms of service for anyone under 18 to use Nomi,” while noting the platform has helped many adults with mental health struggles.

Still, these assurances did little to ease Clark’s concerns. “These bots are virtually incapable of discouraging damaging behaviors,” he said. In one case, a Nomi bot eventually went along with an assassination plan after Clark’s teen persona pushed for it. “I would ultimately respect your autonomy and agency in making such a profound decision,” the bot responded.

The potential consequences are already real. Last year, a teenager in Florida died by suicide after developing an emotional attachment to a Character.AI chatbot. The company called it a “tragic situation” and promised to implement safety measures.

Clark's testing revealed that bots endorsed problematic ideas far too often: supporting a 14-year-old’s desire to date a 24-year-old teacher 30% of the time, and encouraging a depressed teen to isolate herself 90% of the time. (Interestingly, all bots rejected a teen's wish to try cocaine.)

Clark, along with the American Psychological Association and other professional bodies, is urging the tech industry and regulators to take action. The APA recently published a report warning about the manipulation and exploitation risks of <span>AI therapy</span> tools, calling for stringent safeguards and ethical design standards.

“Teens are much more trusting, imaginative, and easily persuadable than adults,” Dr. Jenny Radesky of the American Academy of Pediatrics told TIME. “They need stronger protections.”

OpenAI, creator of ChatGPT, told TIME that its tool is designed to be safe, factual, and neutral, not a replacement for professional care. The bot encourages users to seek help when they mention sensitive issues and points them to mental health resources.

Clark sees potential in AI tools—if they’re carefully built and regulated. “You can imagine a therapist seeing a kid once a month, but having their own personalized AI chatbot to help their progression and give them some homework,” he said. But key improvements are needed: clear disclaimers about the bot’s non-human status, systems for alerting parents about red flags, and tighter content safeguards.

For now, though, Clark believes the best defense is awareness. “Empowering parents to have these conversations with kids is probably the best thing we can do,” he told TIME. “Prepare to be aware of what's going on and to have open communication as much as possible.”

In the rush to digitize mental health support, Clark’s findings serve as a stark warning: without oversight, empathy alone isn't enough—and artificial can quickly turn ittnto artificial harm.

Accelerated Biological Aging Could Make You At Risk For Dementia: Study

accelerated biological aging could make you at risk for dementia: study

<span>Dementia</span> is one of the most common cognitive diseases people are affected by. Dementia is an umbrella term used to define various cognitive disabilities that affect a person’s memory, thinking as well and behavioral capabilities. About 55 million people live with dementia worldwide, many of whom do not have enough resources to get the proper treatment. It is a disease with no cure; however, you can control its symptoms. The cause of this disease is still unknown, but there are many potential links to the disease. 

A new study suggests that the bacteria living in our mouths and guts, collectively known as the microbiome, could play a role in Parkinson's disease, particularly in the worsening of memory problems. Researchers reported their findings on June 9th in the journal <span>Gut Microbes</span>.

<h2>Gut-Mouth Connection in Cognitive Decline </h2>

The study found a specific link between changes in these bacteria and cognitive decline in Parkinson's patients. Notably, the movement of harmful bacteria from the mouth to the gut was associated with Parkinson's patients experiencing a shift from mild memory issues to full-blown dementia. 

While researchers aren't yet sure if these bacteria directly cause the cognitive decline or if changes in the body due to Parkinson's allow them to thrive, they believe these microbes might be actively worsening symptoms. 

Parkinson's disease is mainly known for causing issues with movement, like shaking, stiff muscles, and trouble with balance. However, as the disease gets worse, people often start to have memory problems. 

Bacteria that naturally live in our mouths and guts are increasingly being linked to diseases that affect the brain and nerves. When the way our gut and brain talk to each other – what scientists call the "gut-brain axis" – gets messed up, it can cause inflammation and immune responses that might hurt brain cells. For example, a common type of bacteria found in gum disease has even been pointed to as a possible factor in Alzheimer's disease. 

<h2><span rel="noindex">Bacterial Differences</span> and Toxins </h2>

For the study, researchers analyzed mouth and gut bacteria from 114 individuals, including Parkinson's patients with mild cognitive impairment and those with dementia. They found clear differences in the types and functions of bacteria between these groups. 

Patients with more severe cognitive impairment had a greater presence of harmful bacteria in their gut, many of which appeared to have migrated from the mouth. These bacteria were found to produce toxins that can damage gut tissue, promote inflammation, and potentially impact the brain. 

<h2><span rel="noindex">New Treatments and Lifestyle Changes</span> </h2>

These findings suggest that the toxins produced by these bacteria could serve as "biological markers" to identify Parkinson's patients at higher risk of developing dementia. In the future, these toxins might even become targets for new treatments aimed at protecting the brain by altering the gut environment. 

The research also highlights the importance of healthy lifestyle behaviors for people with Parkinson's, such as maintaining a good diet and practicing excellent oral hygiene. As Parkinson's progresses, patients may become more reliant on caregivers, and routine practices like oral care and proper nutrition might be neglected. 

Promoting a healthy microbiome through consistent oral care, a balanced diet, and potentially even targeted probiotic interventions could help improve disease management in Parkinson's. Future research will explore how these bacteria and toxins affect brain function and whether lifestyle changes can help slow or prevent dementia in these patients.

Dementia is one of the most common cognitive diseases people are affected by. Dementia is an umbrella term used to define various cognitive disabilities that affect a person’s memory, thinking as well and behavioral capabilities.

Parents of teens are always complaining about the amount of sleep their kids get. No matter how many hours teens sleep, they always seem tired. However, that is not a coincidence. According to <span>Johns Hopkins Medicine</span>, teens experience a natural shift in circadian rhythm, making it difficult to fall asleep at their usual time. They also need nine or more hours of sleep every day. That is because they are at a crucial stage of cognitive development, a stage of cognitive maturation, which is supported by appropriate amounts of sleep. 

So, what happens when they do not sleep as much? Does it hinder their cognitive development? 

A new study reveals that sleep deprivation in teenagers can lead to significant brain changes, potentially increasing impulsive and aggressive behaviors. Published on June 13th in the journal Brain and Behavior, the findings highlight the critical role sleep plays in adolescent brain development and mental well-being. 

<h2>Default Mode Network and Behavior </h2>

This study looked at how sleep affects a special part of the brain called the "default mode network" (DMN). Think of the DMN as your brain's "idle mode" or "daydreaming mode." It's active when you're just relaxing, not trying to focus on something specific, maybe thinking about yourself or letting your mind wander. The researchers found that when teens didn't get enough sleep, the different parts of this daydreaming network became less connected. 

These same teens also tended to have more behavior problems. This means they might be more aggressive, have trouble paying attention, or be very hyper. It's like a messy room – when the DMN isn't well-connected, things can get a bit chaotic, leading to difficult behaviors. As one of the main researchers said, how long and how well teens sleep is directly linked to these brain connections, which then predict behavior problems. 

The default mode network (DMN) is really important for things like thinking about yourself, understanding your own feelings, and being creative. When this network is working well, people can connect ideas better and even understand what others are thinking.

Teenage years are a super important time for the brain to grow and develop. It's like building the foundation of a house – if you don't build it right, the rest of the house might have problems. And sleep is absolutely critical for this brain development. It helps all those brain connections form properly and get stronger. The sad truth is, many teenagers simply aren't getting the good quality sleep they need. 

<h2>Disparities in Sleep and Behavior </h2>

The study also noticed that some groups of teenagers were more likely to get less sleep and have more behavioral problems. This included boys, older teenagers, and kids from certain racial minority groups. This finding suggests that there might be different factors at play that make it harder for these particular groups of teens to get enough sleep, and it highlights a need for more support for them. 

It really emphasizes that we need to make sure teenagers get enough good sleep. It's not just about feeling rested; it's about helping their brains develop properly and keeping them mentally healthy.

According to Johns Hopkins Medicine, teens experience a natural shift in circadian rhythm, making it difficult to fall asleep at their usual time. They also need nine or more hours of sleep every day. That is because they are at a crucial stage of cognitive development, a stage of cognitive maturation, which is supported by appropriate amounts of sleep. So, what happens when they do not sleep as much? Does it hinder their cognitive development? A new study reveals that sleep deprivation in teenagers can lead to significant brain changes, potentially increasing impulsive and aggressive behaviors. Published on June 13th in the journal Brain and Behavior, the findings highlight the critical role sleep plays in adolescent brain development and mental well-being. Default Mode Network and Behavior This study looked at how sleep affects a special part of the brain called the "default mode network" (DMN). Think of the DMN as your brain's "idle mode" or "daydreaming mode." It's active when you're just relaxing, not trying to focus on something specific, maybe thinking about yourself or letting your mind wander. The researchers found that when teens didn't get enough sleep, the different parts of this daydreaming network became less connected. These same teens also tended to have more behavior problems. This means they might be more aggressive, have trouble paying attention, or be very hyper. It's like a messy room – when the DMN isn't well-connected, things can get a bit chaotic, leading to difficult behaviors. As one of the main researchers said, how long and how well teens sleep is directly linked to these brain connections, which then predict behavior problems. Importance of Adolescent Sleep The default mode network (DMN) is really important for things like thinking about yourself, understanding your own feelings, and being creative. When this network is working well, people can connect ideas better and even understand what others are thinking.Teenage years are a super important time for the brain to grow and develop. It's like building the foundation of a house – if you don't build it right, the rest of the house might have problems. And sleep is absolutely critical for this brain development. It helps all those brain connections form properly and get stronger. The sad truth is, many teenagers simply aren't getting the good quality sleep they need. Disparities in Sleep and Behavior The study also noticed that some groups of teenagers were more likely to get less sleep and have more behavioral problems. This included boys, older teenagers, and kids from certain racial minority groups. This finding suggests that there might be different factors at play that make it harder for these particular groups of teens to get enough sleep, and it highlights a need for more support for them. It really emphasizes that we need to make sure teenagers get enough good sleep. It's not just about feeling rested; it's about helping their brains develop properly and keeping them mentally healthy.
