Global Rise in Early-Onset Cancer Linked to Obesity and Lifestyle Factors
A major international study has found that several forms of cancer are rising sharply among younger adults worldwide, with obesity and lifestyle changes emerging as key drivers behind the trend.
Published this week in the Annals of Internal Medicine, the study analysed cancer data from 42 countries across five continents between 2003 and 2017. It examined 13 cancer types previously reported to be increasing among younger people, confirming that several are indeed becoming more common in adults aged 20 to 49.
Thyroid, breast, colorectal, kidney, endometrial cancers and leukemia all showed consistent growth across most of the countries studied. Thyroid cancer recorded the steepest rise, with an average annual increase of 3.57%, followed by kidney cancer at 2.21% and endometrial cancer at 1.66%. Colorectal cancer, one of the most closely monitored malignancies among younger populations, rose by 1.45% annually on average. In nearly 70% of countries, new colorectal cancer diagnoses grew faster in younger adults than in older populations.
The researchers said the simultaneous rise across multiple cancer types points to shared risk factors. These may include the global surge in obesity, poor dietary habits, sedentary lifestyles, and widespread antibiotic use, all of which can affect gut health and metabolism.
However, experts emphasized that older adults still account for the majority of cancer diagnoses. While rates among younger adults are climbing, the overall burden remains concentrated in older populations. For instance, in the United States, around 50,000 women under 50 were diagnosed with breast cancer in 2022, compared to more than 210,000 cases in those over 50.
The study’s authors urged caution against focusing prevention efforts solely on early-onset cases, arguing instead for broader public health measures and more research into the underlying causes. “These findings can help guide future research and clinical priorities, including treatment strategies and support needs for younger cancer patients,” the report concluded.
A separate study published in JAMA Internal Medicine last month, however, questioned whether the apparent rise reflects a genuine increase in disease or improved detection. That research found that while diagnoses of several early-onset cancers—such as thyroid, kidney, colorectal, and pancreatic—have doubled since 1992, mortality rates have remained largely unchanged.
The findings suggest that better screening and overdiagnosis could explain part of the increase, rather than a true surge in life-threatening cancers. The authors warned that labeling early-onset cancers as an “epidemic” could lead to unnecessary testing and treatments, imposing emotional, physical, and financial strain on otherwise healthy young adults.

World Cup Emotion Can Strain the Heart, Cardiologists Warn Fans at Risk
As the World Cup begins, medical experts are cautioning football fans with underlying heart conditions that the emotional intensity of matches can place unexpected strain on the cardiovascular system.
Cardiologists say that the excitement, tension, and anxiety generated during high-stakes games can trigger physical reactions similar to intense exercise, raising heart rate, blood pressure, and stress hormones.
“Intense emotions, whether positive or negative, can act as ‘precipitating risk factors’ for cardiovascular events such as heart attack,” said Paola Santalucia, a cardiologist and board member of the European Heart Network.
She explained that moments of extreme excitement, such as a decisive penalty shootout or a last-minute goal, may pose risks for people already living with heart disease. Those with additional risk factors, including hypertension, obesity, or smoking habits, are also advised to be cautious during emotionally charged matches.
Research using wearable devices has shown that during major football events, some fans experience heart rates climbing as high as 150 beats per minute. That level is comparable to sprinting and reflects how strongly the body reacts to emotional stress.
A study examining supporters during the 2025 German Cup final found that even watching from home can significantly affect physiological responses. “They still had an increase in heart rate that compares to walking, even though they didn’t walk,” said Christian Deutscher, professor of sports economics at Bielefeld University and co-author of the study.
He noted that the most intense reactions often occur not during goals themselves, but during moments of uncertainty such as VAR checks, penalty shootouts, or shots striking the post. These unpredictable situations, he said, are what drive the strongest emotional and physical responses among fans.
Deutscher also pointed out that stadium spectators may experience even greater strain due to environmental factors such as heat and alcohol consumption.
However, experts emphasize that football itself is not inherently dangerous. Instead, it is the body’s natural response to excitement that can create temporary stress.
“The adrenergic stimulation is at its max: extreme high blood pressure, high heart rate, and adrenaline, cortisol, skyrocketing,” said Dan Atar, professor of cardiology at Oslo University Hospital. In rare cases, he added, this surge can contribute to the rupture of arterial plaque in vulnerable individuals, potentially leading to a heart attack.
Atar stressed that such events can occur in everyday situations as well, including physical exertion like shoveling snow. “It is in no way dangerous to watch a football game,” he said. “All this is physiologic. It’s not dangerous to be excited.”
Still, he acknowledged that combining emotional stress with alcohol, heat, and pre-existing conditions can increase risk for some viewers.
Doctors advise those at higher risk to continue prescribed medications, limit alcohol intake, avoid smoking, and watch for warning signs such as chest pain or irregular heartbeat.
“The key message is not to avoid enjoying the match, but to do so with moderation and awareness,” Santalucia said.
