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.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
