The purpose of this research study is to learn more about how genetic and lifestyle risks impact the development of the colon cancer microbiome and how this microbiome varies in populations.

Using your stool as a tool we want to identify bacteria in the gut that may help detect, prevent or treat colon cancer. We will look for these bacteria in stool specimens.

Who can join the study?


People from birth to 90 years of age with familial adenomatous polyposis (FAP) or hereditary nonpolyposis colorectal cancer (HNPCC, Lynch Syndrome) OR with a family history of familial adenomatous polyposis (FAP) or hereditary nonpolyposis colorectal cancer (HNPCC, Lynch Syndrome) may join.
