Tracking Colon Cancer with a Camera - Even Before It Develops - How Early Detection Could Slash Colorectal Cancer Deaths by 80%

Colorectal cancer remains one of the deadliest forms of the disease, ranking as the second-leading cause of cancer deaths in Germany and globally. Each year, around 23,000 people in Germany lose their lives to it. Yet, experts say many of these deaths could be avoided through early detection and prevention measures.

The disease often begins with polyps—small growths in the colon that can turn cancerous over time. Regular screenings, such as colonoscopies, help doctors find and remove these polyps before they develop into cancer. During a colonoscopy, a flexible tube with a camera is guided through the colon to check for unusual growths. If no issues are found, patients typically do not need another screening for ten years.

Research shows that early detection could prevent over 80% of colorectal cancer deaths in some cases. Since 2000, Germany has seen a 40% drop in mortality rates, largely thanks to better prevention and screening programmes. In 2023, Westfalen-Lippe recorded around 63,000 colonoscopies under the national early detection scheme—a 3% rise from the previous year. Meanwhile, Mecklenburg-Western Pomerania reports roughly 7,550 residents living with the disease, with about 1,200 new cases diagnosed annually. Certain factors increase the risk of developing colorectal cancer. These include a family history of the disease, smoking, obesity, and diets high in red meat. Recent studies also suggest a possible connection between heavily processed foods and higher cancer risks.

With early detection playing a crucial role, health officials continue to encourage regular screenings for those aged 50 and older. The decline in deaths over the past two decades highlights the impact of prevention efforts. Still, thousands of new cases emerge each year, making ongoing awareness and access to testing vital.
