Overdiagnosis of Prostate Cancer May Explain Wide Variations in Incidence Across Europe, Study Finds
A new study published in the British Medical Journal has revealed that overdiagnosis of prostate cancer in Europe could be contributing to significant differences in cancer incidence rates across countries. While incidence rates varied up to 20-fold between nations, mortality rates only fluctuated by about five times, highlighting a potential disparity in how the disease is being diagnosed and treated.
Overdiagnosis occurs when a tumour is detected that would not have caused symptoms or death during an individual’s lifetime, leading to unnecessary treatments that may negatively impact a patient’s quality of life. The study suggests that widespread use of PSA (prostate-specific antigen) testing, particularly through opportunistic screening, may be driving overdiagnosis.
“The results of this study are compatible with large overdiagnosis of prostate cancer occurring as a consequence of opportunistic screening with PSA testing,” said Dr. Salvatore Vaccarella, the study’s lead author and a scientist at the International Agency for Research on Cancer (IARC).
Prostate cancer is a significant health issue in Europe, representing nearly a quarter of new cancer cases among men in 2020, with over 70,000 deaths attributed to the disease that year. The risk of overdiagnosis and subsequent overtreatment is higher for prostate cancer than for other cancers, such as breast, cervical, or colorectal, the study noted.
Most European countries, except Lithuania, which has implemented a wide screening programme since 2006, rely on individual-based decisions for PSA testing rather than population-wide screening. However, the study warned that PSA testing as part of routine healthcare or opportunistic screening is not optimal for reducing population-level impacts.
A 2009 study found that 23% to 42% of men diagnosed through PSA testing would have lived without ever knowing they had prostate cancer, further raising concerns about the screening method. The researchers emphasized that any future implementation of prostate cancer screening must be carefully designed to reduce the harms of overdiagnosis.
“The results of this new study emphasize the importance of carefully designing prostate cancer screening to minimize overdiagnosis, with proper quality assurance and monitoring,” Vaccarella added.
The findings were based on an analysis of data collected from 1980 to 2017 from men aged 35 to 84 across 26 European countries. However, the researchers cautioned that the observational nature of the study means no direct conclusions about cause and effect can be drawn.

Global Mental Health Cases Near 1.2 Billion as Anxiety and Depression Drive Sharp Worldwide Rise
A major global analysis has found that mental health conditions have surged to an estimated 1.2 billion people worldwide, driven largely by steep increases in anxiety and depression over the past three decades.
The findings, published in The Lancet as part of the Global Burden of Disease Study 2023, show that the number of people living with mental disorders has almost doubled since 1990, marking a 95% rise. Researchers say major depressive disorder and anxiety disorders have seen even sharper growth, increasing by 131% and 158% respectively, making them the most prevalent mental health conditions globally.
The report describes mental illnesses as widespread conditions that create long-term disability and significant human suffering. It also highlights broader consequences for economies and public services, including reduced productivity, lower workforce participation and increasing pressure on health and welfare systems.
Researchers estimate that in 2023 alone, around 620 million females and 552 million males were affected by mental health conditions. While the overall burden is rising across both sexes, the study points to notable differences in the types and prevalence of disorders.
Among women, depression and anxiety were the most commonly reported conditions, alongside higher rates of eating disorders such as anorexia nervosa and bulimia nervosa. The report links this disparity to a mix of biological, social and structural factors, including exposure to domestic violence, sexual abuse, gender inequality and reproductive health-related changes.
In contrast, neurodevelopmental and behavioural disorders, including attention deficit hyperactivity disorder (ADHD), conduct disorder and autism spectrum conditions, were more frequently diagnosed in men.
Teenagers aged 15 to 19 were identified as the group experiencing the highest mental health burden globally, raising concerns about early onset of conditions and insufficient preventive care for young people.
The study identifies several key risk factors associated with mental illness, including childhood sexual violence, bullying and intimate partner violence. These factors are strongly linked to conditions such as depression, schizophrenia, bipolar disorder and anxiety disorders. However, researchers note that such exposures have remained relatively stable over time and account for only a portion of the overall rise.
According to the authors, broader drivers are likely contributing to the increasing prevalence of mental disorders. These include genetic and biological influences, poverty, inequality, and the growing impact of global crises such as armed conflict, pandemics, natural disasters and climate-related stress.
While mental health conditions have long been a leading cause of disability worldwide, the report warns that the situation is worsening. At the same time, health systems have not expanded services at a pace matching demand.
The authors caution that the gap between rising need and limited access to care is becoming more pronounced, leaving millions without adequate treatment or support.
