Colorectal cancer is causing growing concern, particularly because of its spectacular increase in individuals aged under 50. Once considered a disease primarily affecting older people, this type of cancer is now seeing rates rise alarmingly in many parts of the world. This global trend raises crucial questions about the underlying causes of this rise and the measures needed to address it. By exploring risk factors, societal changes and urgent needs for screening and prevention, it becomes imperative to understand why this cancer is affecting more and more young adults. This article will examine in depth the various aspects of this worrying phenomenon.
A worrying global progression
Recent statistics reveal a worrying increase in cases of colorectal cancer among people under 50 across the globe. Researchers, such as those at the American Cancer Society, led by Hyuna Sung, have highlighted this trend through a detailed analysis of data from the World Health Organization. Between 1975 and 2017, colorectal cancer rates increased significantly in 27 countries, including non-Western nations such as Japan and Turkey. This global progression draws attention to a public health challenge that cannot be ignored.
What makes this increase even more concerning is that it cannot simply be attributed to better screening. Indeed, most countries do not carry out systematic testing for colorectal cancer before the age of 50. This suggests that there are deeper underlying causes for this increase in cases among young adults. The link with the Westernization of lifestyles, including diets richer in meat and processed foods, as well as a sedentary lifestyle, seems to emerge as a key factor.
The data also indicates that the most affected geographies share a high human development index, based on life expectancy, education and GDP. This fuels the hypothesis that economic development, often accompanied by cultural and dietary changes, could play a central role in this evolution. While these numbers are alarming, they are only part of the equation. It is crucial to continue investigating to fully understand the reasons for this worrying increase.
Risk factors linked to lifestyle
Modern lifestyle has introduced several factors that increase the risk of colorectal cancer. One of the main contributors appears to be diet. Diets high in red meat and processed foods are strongly associated with an increased risk of developing this cancer. A striking example is Japan, where meat consumption has increased sevenfold since the 1960s, coinciding with a rise in cases of colorectal cancer.

Additionally, a sedentary lifestyle is also recognized as a major risk factor. Modernity has led to a decrease in daily physical activity, whether through increased vehicle use or sedentary office jobs. This sedentary lifestyle, combined with unhealthy eating habits, creates fertile ground for the development of chronic diseases, including colorectal cancer.
Other elements could also contribute, such as pollution or unidentified genetic variations. The researchers emphasize that these factors still require in-depth investigation to be fully understood. Nevertheless, current evidence clearly indicates that lifestyle changes can have a significant impact on reducing risk.
The challenge of early detection
Early detection is a crucial tool in the fight against colorectal cancer, but it remains a major challenge, especially for young adults. Currently, prevention is mainly based on regular screening from the age of 50, or earlier for those at risk. However, with the increase in cases among those under 50, it becomes essential to rethink these screening strategies.
Health systems, often focused on older populations, must adapt to include young adults in their screening programs. Informing young populations about symptoms such as abdominal pain or rectal bleeding becomes a priority. However, these symptoms may go unnoticed or be confused with other benign disorders, making screening and education all the more important.

Emerging initiatives aim to adapt these strategies to better meet the needs of young adults. This includes integrating prevention into already overburdened health systems, highlighting the urgency of understanding the exact causes of this increase. Early detection and education of younger generations are key to reversing this worrying trend.
Impact of economic and cultural development
Economic development and accompanying cultural changes play a significant role in the increase in colorectal cancer cases. Countries with a high human development index, characterized by longer life expectancy, better education and higher GDP, are particularly affected. This suggests that economic development, while beneficial in many ways, can also bring unexpected health challenges.
Cultural changes, such as the adoption of Western diets high in meat and processed foods, are often correlated with an increased risk of colorectal cancer. Additionally, rapid urbanization and resulting sedentary lifestyle also contribute to this trend. It is crucial to understand that economic progress must not come at the expense of public health.
Policymakers and health professionals must collaborate to promote healthy lifestyles, even in contexts of rapid economic growth. This includes encouraging a balanced diet, rich in fiber, as well as promoting regular physical activity. By recognizing the impact of economic development on health, more effective preventive measures can be put in place.

Towards better understanding and prevention
Although significant progress has been made in understanding the increase in colorectal cancer among young adults, many questions remain unanswered. Researchers continue to explore various factors, such as pollution and genetic variations, to get a more complete picture of the underlying causes.
More comprehensive data collection is needed to fill current gaps, particularly in underrepresented regions such as Africa and parts of Asia. A thorough understanding of regional disparities is essential to develop prevention strategies adapted to each context.
Initiatives to educate young adults about the symptoms and risk factors of colorectal cancer are crucial. By integrating these efforts into public health systems, it is possible to reduce the incidence of this devastating disease. Prevention, combined with appropriate screening strategies, can play a key role in combating this alarming trend.
As we continue to explore the causes and possible solutions, it is essential to ask: what additional steps can be taken to protect younger generations from this growing threat? In seeking answers, we must commit to creating a healthier future for all.
