The number of colorectal cancer cases in people under 50 is rising worldwide, especially in high-income countries. Possible causes include Western diets, obesity, lack of exercise, and the use of antibiotics, especially in early life and adolescence. However, if colorectal cancer is detected early, the chances of recovery are significantly higher. That is why Hahn-Schickard is working with project partners at the University Hospital Schleswig-Holstein and the German Cancer Research Center to develop new methods for detecting cancer in blood samples.
