Genetics: Colorectal Cancer

Genetics and Cancer - Hereditary Nonpolyposis Colon Cancer (HNPCC)
This type of colon cancer is also known as Cancer Family Syndrome. It raises the risk for other cancers, including those of the endometrium, stomach, small intestine, liver and biliary tract, brain, ovary, ureters, and renal pelvis.
Genetics and Cancer - Other Colorectal Cancer Syndromes
Several rare syndromes raise the risk for colorectal cancer. These disorders include Turcot syndrome, Peutz-Jeghers syndrome, juvenile polyposis coli, and MYH-associated polyposis.
Genetics and Cancer--Familial Adenomatous Polyposis (FAP)
FAP is a syndrome characterized by a large number of benign polyps in the colon and rectum. Without treatment, a person with FAP has a nearly 100 percent risk of colorectal cancer.
