Colorectal cancer is a life-threatening disease affecting the large bowel. Improved diagnostic methods could notably increase the chance of a disease-free life due to a timely diagnosis followed by effective, personalized treatment. Genos is a partner in GlyCoCan, a network focused on colorectal cancer research in the field of glycobiology, which connects 13 PhD students and their experienced mentors all across Europe. By investigating the role of glycans (complex carbohydrates present on human cells including cancer) they are paving the way for precision medicine in the field of oncology.
