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.

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.

Recent headlines touting that “exercise is better than drugs” for cancer remission have captured the public’s imagination, sparking debate between proponents of “natural” interventions and advocates of traditional medicine. However, analysis of the latest landmark research reveals the reality is more nuanced than the catchy titles suggest – and the implications for cancer patients, including those in Thailand, could be profound if correctly understood and applied.

At the source of the recent media buzz is a major study published in the New England Journal of Medicine, focusing on patients recovering from colon cancer, the world’s third-most common cancer and a leading cause of cancer-related death. Conducted between 2009 and 2024 across six countries, including Australia and Canada, the clinical trial followed 889 patients who had undergone colon cancer surgery and completed chemotherapy. Participants were randomized into two groups: one received a rigorously structured, professionally supervised exercise programme tailored to cancer survivors; the other group received health education materials on the benefits of physical activity and healthy eating, but without extra support or monitoring (The Guardian, Oncology Central).

A large international study shows that a supervised, structured exercise program after standard colon cancer treatment can improve long-term outcomes. For Thai readers, the finding underscores how lifestyle support can play a meaningful role in survivorship care without replacing medicine.

From 2009 to 2024, 889 colon cancer patients who finished chemotherapy were randomized to a guided exercise program or to a lifestyle-education group. The exercise plan was personalized and supervised, with weekly in-person coaching for six months, then gradually reduced as participants gained confidence. Target goals were 150 minutes per week of moderate to vigorous activity, including brisk walking, cycling, swimming, or circuit classes. The control group received lifestyle advice on activity and healthy eating without extra coaching.

A ground-breaking international trial has revealed that regular exercise can dramatically increase survival rates among colon cancer patients, with those who participated in a structured program experiencing a 37% reduction in risk of death and significantly lower cancer recurrence rates. This latest research, published in the prestigious New England Journal of Medicine, could fundamentally change global approaches to treating colon cancer—including new implications for clinical practice in Thailand.

In a comprehensive study involving 889 colon cancer patients, researchers assessed the impact of sustained physical activity after chemotherapy. Half of the participants were placed on a supervised exercise regimen, while the other half received standard health advice through informational leaflets. After a five-year follow-up, the results were dramatic: 80% of those in the exercise group remained cancer-free, compared with just 74% in the control group—indicating a 28% reduction in the chance of recurrence or a new cancer developing (BBC News).

A major international trial shows that regular, supervised exercise after chemotherapy can significantly improve survival for colon cancer patients. The study found that participants in a structured program had a 37% lower risk of death and reduced cancer recurrence compared with those who received only standard health advice. Published in a leading medical journal, these findings have important implications for cancer care in Thailand.

Data from the study, which followed 889 patients over five years, indicate that after treatment, those who engaged in exercise maintained cancer-free status at higher rates. About 80% of the exercise group remained free of cancer compared with 74% in the control group, suggesting a meaningful reduction in recurrence risk. While the results are promising, researchers emphasise that even relatively modest activity can yield benefits when incorporated into care plans.

A beloved physical activity endorsed by millions for its health benefits—long-distance running—may be unexpectedly associated with a higher risk of developing precancerous colon growths among young adults, according to a new study presented at the prestigious American Society of Clinical Oncology (ASCO) 2025 conference in Chicago. The study, conducted by researchers based in Washington, DC, challenges the prevailing wisdom that vigorous aerobic exercise is universally protective against all forms of cancer, raising pressing questions for health-minded Thais—especially the country’s growing cohort of marathon and ultramarathon enthusiasts.

A widely celebrated form of exercise, long-distance running, may be linked to an unexpected risk among certain young adults. A study presented at ASCO 2025 in Chicago found a higher-than-expected rate of colon adenomas—precancerous growths—in adults aged 35 to 50 who regularly run ultramarathons or multiple marathons. The results prompt careful discussion for health-minded Thai runners, where endurance events have surged in popularity in recent years.

The investigation examined 100 runners who completed at least two ultramarathons (over 50 km) or five standard marathons (42 km) within a defined period. Among participants, 41% had at least one adenoma and 15% had advanced adenomas. These rates appeared higher than typical figures for the general population. About half of those with advanced lesions reported rectal bleeding, a symptom sometimes mistaken for benign exercise-related issues such as runner’s colitis.

A surge of scientific research in 2024 is intensifying fears that Campylobacter, a bacterium commonly found in undercooked chicken, may be fueling a global epidemic of colon cancer—particularly among younger adults. Newly published findings show that infections caused by this foodborne pathogen not only trigger stomach illness but might also accelerate the onset and spread of deadly colorectal tumors, according to leading researchers. As Thailand grapples with rising cases of both campylobacteriosis and early-onset colon cancer, these revelations could reshape food safety policy and public health strategies nationwide.

A surge of 2024 research is fuelling concern that Campylobacter, a bacterium commonly found in undercooked chicken, may be linked to a global rise in colon cancer, including among younger adults. Latest findings suggest that infections from this foodborne pathogen could not only cause stomach upset but also influence the initiation and spread of colorectal tumors. For Thailand, where poultry is a dietary staple, these developments may influence national food safety and public health strategies.

A new study highlights gut bacteria as a potential driver behind the global rise in colorectal cancer among people under 50. The research suggests that imbalances in the gut microbiome can damage the colon lining, trigger chronic inflammation, and increase cancer risk long before middle age. For Thailand, where dietary habits and antibiotic use are evolving rapidly, these findings emphasize the importance of gut health in cancer prevention.

Colon cancer is increasingly diagnosed in younger adults in both Western countries and Thailand. Thailand’s public health data show a steady uptick in colorectal cancer among individuals under 50 over the past decade, echoing a global pattern that has concerned researchers and policymakers. While genetics and lifestyle factors like inactivity, obesity, and processed-food diets contribute to risk, scientists are now focusing on the gut’s biological environment as a key factor.

A new investigation into the factors driving a troubling worldwide increase in colon cancer among young adults points to damage caused by certain gut bacteria as a potential culprit, according to recently reported research. The findings, which come amid mounting concern about the sharp rise in colorectal cancer diagnoses in people under 50, highlight the possible role of the gut microbiome—a bustling ecosystem of trillions of organisms living in the digestive tract—in influencing cancer risk well before middle age. The research underscores an urgent need for both the medical community and the wider public in Thailand to consider how diet, antibiotics, and lifestyle choices may impact long-term gut health and, consequently, cancer prevention.

A leading internal medicine specialist has sounded the alarm on the “alarming rise” of colon cancer in Generation Z and Millennials, urging young people to look out for five critical warning signs as diagnoses soar worldwide. Dr. Zion Ko Lamm, whose insights have attracted nearly a million followers on social media, emphasizes that colon cancer is not just an “old person’s disease”—incidence among the under-50s has jumped by 80% over the past thirty years, even as rates in older adults have declined or stabilised. This alarming trend, detailed in a recent article by the Daily Mail (source), raises urgent questions for Thai healthcare and society, where rapid lifestyle changes could echo Western patterns.

A leading internal medicine specialist warns that colon cancer is rising among Gen Z and Millennials worldwide, urging younger people to watch for five critical signs. Dr. Zion Ko Lamm, whose insights have captivated nearly a million followers, stresses that colon cancer is not confined to older adults. In fact, incidence among those under 50 has climbed about 80% over thirty years, even as rates in older populations have declined or stabilized. This trend raises urgent questions for Thailand, where rapid lifestyle changes may mirror Western patterns.

A sweeping new review of scientific studies suggests a strong connection between vitamin D and reduced risk of colorectal cancer, with some findings indicating up to a 58% lower risk among those with the highest vitamin D intake. This revelation, published in April 2025 in the journal Nutrients, could have far-reaching implications for cancer prevention strategies in Thailand and across the globe, offering a natural, affordable, and accessible way to combat one of the world’s most common and deadly cancers (EatingWell).

A comprehensive review of 50 high-quality studies finds a meaningful link between higher vitamin D levels and lower colorectal cancer risk. Some studies suggest up to a 58% reduction among individuals with the highest intake, a finding that could influence cancer prevention strategies in Thailand and beyond. The research, published in Nutrients in 2025, emphasizes vitamin D as a practical and accessible tool in public health.

Colorectal cancer remains a major global health challenge, ranking among the most common cancers for both men and women. In Thailand, the disease has become more prevalent in recent years, with dietary shifts toward processed foods and lower fiber intake contributing to risk. Public health leaders are urging culturally appropriate prevention efforts that align with Thai lifestyles and dietary patterns.

Recent research published in the journal Cancer reveals that colon cancer survivors who engage in regular physical activity may enjoy longer lives than those who do not. The study, led by Dr. Jeff Meyerhardt from the Dana-Farber Cancer Institute, highlights the potential of exercise to significantly influence a patient’s long-term prognosis by not only reducing cancer mortality but surpassing the life expectancy of individuals who haven’t experienced cancer.

With colon cancer marking a significant cause of cancer-related deaths worldwide, including an alarming rise among younger adults in the United States, the implications of this research are profound. Improved survival rates due to exercise could be a game-changer for patients in Thailand, where sedentary lifestyles are increasingly common among urban populations. Regular exercise could mitigate this trend, offering hope for prolonged life and improved quality of life for Thai patients battling colon cancer.

A new study published in Cancer suggests that colon cancer survivors who stay physically active live longer than those who remain sedentary. Led by researchers from a major cancer institute, the work highlights exercise as a potential factor in improving long-term prognosis, not only lowering cancer mortality but sometimes surpassing the life expectancy of people without cancer.

Colon cancer remains a leading cause of cancer deaths worldwide, with a concerning rise among younger adults in some regions. For Thai readers, these findings offer a hopeful angle: integrating regular activity could help improve survival and quality of life for survivors amid rising urban sedentary trends. Exercise can be a practical, affordable intervention that fits into Thailand’s health priorities.

Colon cancer is a global concern, and Thailand is increasingly affected. Recent findings from reputable health institutes show a rising trend in younger adults and a persistent burden among older adults, underscoring the need for targeted prevention and early detection across the country. While rates among seniors remain a major focus, health experts warn that a 2.4% yearly increase among people under 55 in recent years calls for proactive community strategies in Thailand.

Colon cancer is rising as a global health concern, and Thailand is no exception. Recent data show colorectal cancer ranking as a leading cause of cancer-related deaths, with younger adults increasingly affected. In 2020, a notable share of diagnoses occurred in people under 50, underscoring the need for early screening and heightened awareness across Thai communities.

In Thailand’s regional context, shifting lifestyles—more sedentary work, faster, less-balanced meals, and growing urbanization—mirror Western trends that may contribute to higher cancer risk. Early detection matters: when colon cancer is found early, survival rates are high. This highlights the life-saving potential of proactive screening and regular health checkups.
