Preventing colorectal cancer often comes down to a single, proactive decision: screening. According to gastrointestinal specialist Luc Colemont, the impact of widespread screening could be transformative, potentially reducing the number of colorectal cancer cases by nearly half if universal participation were achieved.
As the founder of the non-profit organization Stop Darmkanker, Colemont emphasizes that early detection is the most effective tool in combating this disease. While screening programs are available, a significant gap remains in participation rates. In Flanders, for example, Colemont notes that approximately 48 percent of the target population does not participate in screening according to data cited by the specialist.
This lack of participation is a critical public health concern, as colorectal cancer is often asymptomatic in its early stages. By the time symptoms appear, the disease may have progressed, making treatment more complex and less effective. Colemont’s advocacy focuses on closing this gap to save lives through early intervention.
The Critical Importance of Early Detection
Colorectal cancer typically develops from small growths called polyps. When detected early through screening, these polyps can often be removed before they ever become cancerous. This preventative approach is why Colemont asserts that nearly half of these cancers could be avoided if everyone adhered to screening guidelines.
The broader context of cancer prevention is equally stark. We see estimated that one in three cancer diagnoses is avoidable, which translates to approximately 15,000 avoidable cases annually in Flanders per reports from the region. This highlights the necessity of shifting the medical focus from treatment to primary and secondary prevention.
Addressing the Age Gap: Risks for Those Under 50
While traditional screening programs often target older adults, there is a growing concern regarding the incidence of the disease in younger populations. Dr. Luc Colemont has issued warnings regarding colorectal cancer in individuals under the age of 50.
For those who may not yet be eligible for national screening programs but are concerned about their risk, Colemont points out that testing options are accessible. Screening tests are available for purchase at pharmacies and supermarkets, providing a low-barrier way for younger individuals to monitor their health as noted in February 2026 reports.
Overcoming Barriers to Screening
The fact that nearly half of the eligible population in certain regions avoids screening suggests significant psychological or systemic barriers. These may include fear of the procedure, a lack of perceived risk, or simple procrastination. Colemont and Stop Darmkanker work to dismantle these barriers by educating the public on the simplicity and efficacy of modern tests.
The goal is to move toward a society where screening is viewed as a routine part of health maintenance, similar to blood pressure checks or dental cleanings. By normalizing the process, health officials hope to increase the 48 percent non-participation rate and move closer to the goal of significantly reducing cancer mortality.
Key Takeaways for Colorectal Health
- Screening Impact: Universal participation in screening could potentially reduce colorectal cancer cases by nearly 50%.
- Participation Gap: In Flanders, roughly 48% of the target group currently does not participate in screening.
- Younger Adults: Risks exist for those under 50; tests are available at pharmacies and supermarkets for those seeking early detection.
- Preventability: Approximately one-third of all cancer diagnoses are considered avoidable through prevention and early detection.
