Early-Onset Cancer Rates Rising in U.S., But Deaths Mostly Stable, Study Finds

Published

on

A new U.S. government study has revealed that while cancer diagnoses among people under 50 are on the rise, the overall death rates for most types of cancer in this age group remain stable.

Published Thursday in the journal Cancer Discovery, the study is one of the most comprehensive assessments to date of early-onset cancers, analyzing data from more than two million cases diagnosed in Americans aged 15 to 49 between 2010 and 2019.

The findings show that 14 out of 33 cancer types had increasing incidence rates in at least one younger age group. The most significant increases were seen in breast, colorectal, kidney, and uterine cancers. Women accounted for about 63 percent of the early-onset cases.

This pattern generally reflects something profound going on,” said Tim Rebbeck of the Dana-Farber Cancer Institute, who was not involved in the study. “We need to fund research that will help us understand why this is happening.”

The study found that, compared to 2010 data, there were 4,800 more breast cancer cases, 2,000 additional colorectal cancers, 1,800 more kidney cancers, and 1,200 extra uterine cancers by 2019.

Despite the rising numbers, researchers emphasized a key reassurance: death rates for most of these cancers are not increasing. However, exceptions were noted—colorectal, uterine, and testicular cancers saw slight rises in mortality among younger adults.

The causes behind the rise in early-onset cancers are not fully understood. The study’s datasets do not include information on potential risk factors such as obesity, lifestyle, or access to healthcare. However, researchers, including lead author Dr. Meredith Shiels of the National Cancer Institute, highlighted obesity as a possible driver.

Several of these cancer types are known to be associated with excess body weight,” said Dr. Shiels. She also pointed to advances in detection and changing screening practices as possible contributors to earlier diagnoses.

Breast cancer trends may also be influenced by shifting reproductive patterns, such as women having children later in life, which has been associated with increased cancer risk due to fewer years of pregnancy and breastfeeding—factors known to lower risk.

Not all cancer types followed the upward trend. Rates of more than a dozen cancers, including lung and prostate cancer, are decreasing among younger people. Researchers attribute the lung cancer decline to reduced smoking rates, while updated PSA screening guidelines are likely behind the drop in prostate cancer diagnoses.

Experts plan to convene later this year to further investigate the growing early-onset cancer burden and explore targeted prevention strategies.

AI Tool Could Help Target Prostate Cancer Treatment, Improve Patient Outcomes

Published

on

A new artificial intelligence (AI) tool could significantly improve outcomes for prostate cancer patients by identifying who would benefit most from the drug abiraterone, according to UK researchers presenting their findings at the American Society of Clinical Oncology’s annual meeting this week.

The tool analyzes tumour biopsy images to detect hidden biomarkers that predict whether a patient is likely to respond well to abiraterone, a drug known to nearly halve the risk of death for some men with prostate cancer. While effective, abiraterone is expensive and carries potential side effects such as high blood pressure, liver issues, and diabetes. These concerns have led health systems to prescribe it cautiously.

“This research shows that we can pick out the people who will respond best to abiraterone, and those who will do well from standard treatment alone – hormone therapy and radiotherapy,” said Professor Nick James, co-lead of the study from the UK’s Institute of Cancer Research.

The AI model was developed by studying tumour pathology slides and identifying molecular markers invisible to the human eye. Researchers then applied the tool to biopsy images from over 1,000 men enrolled in an earlier clinical trial on prostate cancer therapies.

Among patients whose tumours tested positive for the biomarker, abiraterone cut the five-year mortality rate from 17% to 9%. In contrast, those without the biomarker did not show a significant benefit from the drug, suggesting they could avoid unnecessary side effects and rely on standard treatments instead.

“This study shows, in a very large cohort of patients, that novel algorithms can be used to extract information from routinely available pathology slides to tailor these treatments to specific patients and minimise over-treatment whilst maximising the chance of cure,” said Professor Gert Attard of the University College London Cancer Institute, the study’s co-lead.

In the UK, access to abiraterone varies. While it is approved for use in newly diagnosed high-risk patients in Scotland and Wales, England’s NHS only offers the drug once the cancer has spread. The researchers called for policy changes, estimating that up to 8,400 men in England could benefit from earlier access.

“Access to this life-extending drug is currently a postcode lottery,” James said. “Those living in Scotland and Wales can receive the treatment for free — others cannot.”

Prostate cancer remains one of the most common cancers among men, with nearly 336,000 new cases diagnosed annually in the European Union.

New Study Finds Two in Five European Teens Struggling with Mental Health, Girls Most Affected

Published

on

A major new study has revealed that nearly 40% of European teenagers are experiencing poor mental well-being, with adolescent girls reporting significantly worse outcomes than boys across all 37 countries surveyed.

The findings come from the European School Survey Project on Alcohol and Other Drugs (ESPAD), which, for the first time in its 30-year history, included questions on mental health. The survey collected responses from nearly 114,000 students aged 15 and 16 across Europe.

According to the report, 59% of teens were classified as having “good mental well-being”—scoring above 50 on a standardized index measuring factors such as feeling cheerful, waking refreshed, and interest in daily life. However, the data revealed stark regional and gender disparities.

Teens in Nordic countries reported the highest levels of mental well-being, with the Faroe Islands (77%), Iceland (75%), and Denmark (72%) topping the list. In contrast, adolescents in Ukraine, still reeling from the ongoing war, ranked lowest, with only 43% reporting good mental health. Other countries with notably low scores included the Czech Republic (46%), Hungary (47%), and both Cyprus and Poland (49%).

The study highlighted that boys consistently reported better mental health than girls across all participating nations. On average, 69% of boys had good mental well-being, compared to just 49% of girls. The gap was particularly wide in countries such as Italy and Poland, where twice as many boys as girls reported feeling mentally well.

In Sweden, although overall well-being was relatively high at 62%, a closer look revealed that four in five boys reported positive mental health, while fewer than half of girls did.

Experts warn these findings point to a growing mental health crisis among Europe’s youth, intensified by social pressures, educational disruption during the COVID-19 pandemic, and the emotional toll of global conflicts and economic instability.

“Mental health is deeply connected to the broader social environments in which young people grow up,” said Kadri Soova, director of Mental Health Europe. Though not involved in the study, Soova urged policymakers to develop targeted support systems, especially for vulnerable groups like adolescent girls.

She also emphasized the importance of addressing both longstanding and emerging issues, including substance use and digital risks. “By investing in mental health education and accessible support, we can create conditions for all young people to thrive,” she said.

Mental health concerns among youth are not confined to Europe. A recent Lancet analysis found rising rates of mental health disorders among adolescents worldwide over the past decade.

E-Cigarette Use Rises as European Teens Turn Away from Alcohol and Drugs, Survey Finds

Published

on

Brussels: Teenagers across Europe are increasingly turning to e-cigarettes while reducing their use of alcohol and illegal drugs, according to the latest findings from the European School Survey Project on Alcohol and Other Drugs (ESPAD).

The 2024 report, released this week, analyzed the habits of nearly 114,000 students aged 15 and 16 in 37 countries, offering a comprehensive view of substance use, digital behavior, and lifestyle choices among European adolescents.

Vaping Surges as Smoking Trends Shift

Although traditional cigarette smoking has declined significantly since the 1990s, the report highlights a sharp rise in e-cigarette use. About 44% of surveyed students reported trying e-cigarettes at least once, with 22% using them regularly—up from 14% in the previous survey five years ago.

Researchers noted that many teenagers perceive vaping products as easy to access, contributing to a broader shift toward alternative nicotine consumption. Alarmingly, daily smoking among preteen girls has shown a recent increase, despite the overall decline in cigarette use.

Alcohol Consumption Falls, but Early Drinking Persists

Alcohol use continues to decline across Europe, both in terms of general consumption and binge drinking. However, early initiation remains a concern, with around one-third of teens reporting their first alcoholic drink at age 13 or younger. Approximately 75% of students have tried alcohol at some point.

Denmark (55%), Germany (49%), and Austria (48%) recorded the highest rates of heavy teenage drinking, underscoring ongoing regional challenges despite broader positive trends.

Cannabis Remains Most Common Illegal Drug

Cannabis remains the most widely used illegal drug among European teens, with 12% of students saying they had tried it—a figure that marks the lowest rate since 1995. While boys remain more likely than girls to use cannabis, the gender gap is narrowing.

Other substances such as cocaine, ecstasy, LSD, and amphetamines were used by around 2% of students. Prescription drug misuse is also on the rise, with 8.5% having taken tranquillisers or sedatives and 6.9% using painkillers for recreational purposes.

Shifts in Digital Habits and Gambling

Gaming is a central part of teenage life, with 80% playing video games monthly. Notably, girls’ participation in gaming has surged, rising from 22% in 2015 to 71% last year. At the same time, concerns around social media use are growing. Nearly half of teens reported problematic social media behavior, with increases in harmful use particularly pronounced among boys.

Gambling remains prevalent, with nearly one in four teens having gambled for money in the past year. Rates vary widely—from 9.5% in Georgia to 45% in Italy—despite tighter regulations aimed at protecting minors.

The ESPAD report, conducted every four years, offers critical insights for policymakers and public health officials as they address emerging challenges in youth behavior across Europe.
