Genetics: Colorectal 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.
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.
Ovarian Cancer as Part of Lynch Syndrome
A woman with this type of hereditary colon cancer is at increased risk for ovarian cancer.
