A new study raises important questions about the health effects of extreme endurance running, including potential precancerous changes in the colon. For Thailand’s growing running community, the findings call for careful interpretation and practical guidance from healthcare professionals.

In Thailand, running has become a beloved activity that blends fitness with charity and temple-based community events. Many families view long-distance running as a virtuous pursuit aligned with Buddhist values of caring for the body. The new findings therefore carry broad relevance for runners and their households, not just individual athletes.

A small new study found high rates of precancerous colon polyps in marathon and ultramarathon runners. The research raised questions about extreme exercise and early-onset colorectal risk (New York Times) (New York Times).

The finding matters because many Thais run for health and for charity. The result may change how doctors advise endurance athletes in Thailand.

An oncologist in Virginia recruited 100 runners aged 35 to 50 for colonoscopies. He saw almost half with polyps and 15 percent with advanced adenomas (New York Times).

A groundbreaking medical investigation has uncovered disturbing correlations between extreme endurance running and precancerous colon abnormalities, potentially transforming how physicians advise Thailand’s rapidly expanding marathon community. The research challenges decades of assumptions about exercise and cancer prevention, revealing that even activities traditionally considered purely beneficial may carry hidden health risks that demand immediate attention from Thai healthcare providers.

The study’s implications resonate powerfully throughout Thailand, where marathon participation has surged dramatically in recent years, with charitable running events becoming deeply embedded in temple culture and community fundraising traditions. Thai families increasingly encourage running as virtuous physical activity that aligns with Buddhist principles of caring for the body, making these unexpected findings particularly significant for a population that views distance running as inherently healthy and spiritually meaningful.

A major new review has found that today’s young adults face a dramatically higher risk of rectal cancer, revealing that individuals born in 1990 are up to four times more likely to develop this malignancy compared to those born just 40 years earlier. The sweeping analysis, published in the British Journal of Surgery and led by scientists at the Dana Farber Cancer Institute and Harvard Medical School, documents surging rates of gastrointestinal cancers—not just in the United States but across developed nations following Western lifestyle patterns. These findings have far-reaching implications for global health, and offer critical lessons for Thailand as it grapples with shifting demographic and health threats.

Alarming international research published in the British Journal of Surgery documents that young adults born in 1990 face up to four times higher rectal cancer risk compared to those born just 40 years earlier, revealing a catastrophic generational shift in gastrointestinal cancer patterns that reflects the devastating health consequences of Western lifestyle adoption—a trend with urgent implications for Thailand as urbanization, dietary modernization, and sedentary behaviors accelerate across all socioeconomic levels. This comprehensive analysis from Harvard Medical School and Dana Farber Cancer Institute scientists demonstrates surging rates of early-onset gastrointestinal cancers across developed nations, offering critical warnings for Thai healthcare policy as the kingdom confronts similar demographic and lifestyle transformations.

An international study in the British Journal of Surgery raises a stark warning for Thailand: people born in 1990 may face up to four times higher rectal cancer risk than those born four decades earlier. Researchers from Harvard Medical School and Dana-Farber Cancer Institute link this generational surge to lifestyle changes associated with urbanization, processed foods, and sedentary behavior—patterns now spreading across Thai cities and towns.

Data from multiple developed nations show early-onset gastrointestinal cancers—colorectal, stomach, esophageal, and pancreatic—are rising among adults under 50. Colorectal cancer is increasingly a leading cancer killer for men under 50 and a growing threat for women in the same age group. Experts emphasize that similar trends are emerging in wealthy Asian countries pursuing rapid modernization, underscoring Thailand’s imminent risk as urban living and dietary shifts accelerate.

A new nationwide survey published in June 2025 has revealed a remarkable reduction in hepatitis C prevalence across Thailand—a development hailed by public health leaders as evidence that the country’s decades-long prevention and screening efforts are working. The research, conducted in four regions of Thailand among over 6,000 participants, found that the current rate of hepatitis C infection is just 0.56%, down from 2.15% in 2004 and 0.94% in 2014. This progress comes even as the World Health Organization warns globally that viral hepatitis deaths are rising, with 1.3 million fatalities each year according to its 2024 Global Hepatitis Report (healio.com), making Thailand’s performance uniquely encouraging (nature.com).

A nationwide survey released in mid-2025 shows a sharp decline in hepatitis C prevalence across Thailand, highlighting decades of prevention and screening success. Conducted across four regions with more than 6,000 participants, the study found an overall infection rate of 0.56 percent, down from 2.15 percent in 2004 and 0.94 percent in 2014. Health authorities view Thailand’s progress as a model of effective public health investment and collaboration.

Hepatitis C is often called the “silent” infection because many people have no symptoms until extensive liver damage occurs. Thai health leaders emphasize broad screening, especially for high-risk groups and individuals born before 1992, the year universal HBV vaccination began for newborns. The Ministry of Public Health has adopted a dual “test-and-treat” approach, offering rapid diagnostic testing, molecular confirmation, and access to direct-acting antivirals that cure up to 95 percent of cases.

A new wave of research has sounded the alarm on a widespread but often overlooked health threat: metabolic dysfunction-associated steatohepatitis (MASH), a “silent disease” that afflicts about 16 million Americans—most of whom don’t know it. Recent studies published in major medical journals, including The Lancet and findings summarized by the Daily Mail, reveal that a staggering 80% of those living with this deadly form of fatty liver disease remain undiagnosed, raising urgent concerns for public health systems, including here in Thailand (source, Wikipedia, Asia-Pacific Trends PDF).

A surge of new research warns of a growing, largely hidden health crisis: metabolic dysfunction-associated steatohepatitis (MASH). Known as a silent liver disease, MASH affects millions but remains undiagnosed in many cases. Recent studies in major medical journals and consolidated summaries highlight that a large majority of people with this dangerous fatty liver condition do not know they have it. In Thailand, experts say trends mirror global patterns driven by urban lifestyles, obesity, and metabolic syndrome.

Prostate cancer has once again captured global attention following the recent diagnosis of former US President Joe Biden, shining a spotlight on a disease that is the most common cancer among men worldwide. While headlines often tout new prevention measures or promising lifestyle tweaks, leading experts have clarified that the factors most responsible for a man’s risk of developing prostate cancer lie largely beyond individual control: age, ethnicity, and family history. This evidence-based perspective, backed by the latest research, has vital implications for men in Thailand, where rising cancer rates are signaling the need for smarter screening and public health strategies.

Prostate cancer remains the most common cancer among men worldwide, a reality highlighted again by high-profile diagnoses. For Thai readers, experts emphasize a clear, evidence-based message: age, ethnicity, and family history are the main risk factors, while individual lifestyle choices have a limited impact on overall risk. This perspective shapes how Thailand should approach smarter screening and public health strategies.

Thai cancer statistics show a rising burden. In 2022, the incidence was 7.6 cases per 100,000 men. While this is lower than in Europe or North America, the trend is upward as medical care improves and life expectancy grows. Projections suggest new cases could double by 2040, underscoring the need for accessible, evidence-based screening programs across the country.

A recent research breakthrough offers new insight into why colorectal cancer cases are climbing among younger adults, a trend that has alarmed public health officials worldwide, including in Thailand. For years, scientists have noted a disturbing shift: while colorectal cancer rates decline among older adults, young people are increasingly being diagnosed, often at later—more dangerous—stages. The implications are significant for Thailand, where cancer remains one of the top causes of death, and awareness of early-onset colorectal cancer is still developing.

New research is shedding light on why colorectal cancer cases are climbing among younger adults. The findings suggest that early-onset colorectal cancer may be a biologically distinct disease, not just a younger version of the traditional illness. This has clear implications for Thai readers, where cancer remains a leading cause of death and awareness about early detection is growing.

Experts examined genetic and environmental factors in patients diagnosed before age 50. The study found unique tumor biology in younger patients compared with older groups. This points to the need for age-specific awareness, screening strategies, and treatment approaches that reflect these differences.

A startling new study is sounding the alarm about a possible factor behind the rising rates of colorectal cancer in younger people—a gut-derived toxin that could be fueling early-onset cases of the disease. The research, recently covered by NPR (source), shines a spotlight on an emerging health concern that cuts across demographics worldwide, including right here in Thailand.

For many Thais, colorectal cancer has been long thought of as an illness affecting mainly older adults. However, recent statistics from both global and Thai cancer registries show a disquieting trend: people under 50 are being diagnosed with the disease at significantly higher rates than in previous decades (source, source). As lifestyles change, with more Westernized diets, sedentary habits, and rising obesity, experts have wondered what else might be driving the sharp increases among the young.

A new international study highlights a potential factor behind increasing colorectal cancer rates among younger people: toxins produced by gut bacteria. The findings, covered by health outlets, spotlight a health challenge that could affect Thailand as the population’s diet and lifestyle shift.

Globally and in Thailand, colorectal cancer is increasingly diagnosed in people under 50. Health registries show rising incidences among the young, a trend associated with Westernized diets, sedentary living, and growing obesity. Researchers are exploring additional contributors, including gut bacteria that generate harmful toxins.
