Research

Mayo Clinic doctors and researchers in gastrointestinal cancer research and gastroenterology and hepatology research study new ways to prevent, diagnose and treat colon cancer.

Colon cancer research is conducted in coordination with Mayo Clinic Comprehensive Cancer Center. Mayo Clinic Comprehensive Cancer Center receives funding from the National Cancer Institute and is designated as a comprehensive cancer center. This designation recognizes the institution's scientific excellence and multidisciplinary resources focused on cancer prevention, diagnosis and treatment.

Mayo Clinic also keeps a Colon Cancer Family Registry as part of an international research consortium studying the genetic and molecular epidemiology of colorectal cancer. A central goal of the Colon Cancer Family Registry is the translation of colorectal cancer research to the clinical and preventive settings for the benefit of registry participants and the general public.
